Hi Friends! Hope you’re well. I welcome you on board. In this post today, I’ll discuss What is VPN & How Does it Work?
A VPN stands for Virtual Private Network. It is used to hide your online activities from your ISP (internet service provider) and other third parties. This means you can surf online, share your credentials and send and receive data online with confidence. No one can sneak into your personal data and browsing history. Plus, it gives access to prohibited websites that you cannot see with your regular internet connection. A VPN hides your IP address and replaces it with another string of numbers from another location, which means no one can identify your actual location and IP address. Most companies and individuals use VPN to keep their personal data from the eyes of potential hackers and cyber threats. We will try to cover everything about VPN buy you can learn more about VPN here.
I suggest you read this post all the way through as I’ll be covering What is VPN & and How Does it Work.
Let’s jump right in.
A VPN is a virtual network that keeps your online activities secure and private. It blocks your actual IP address and your identity, which means no outsider can break into what you’re doing online. A VPN keeps location and browsing history private, making it difficult for third parties to trace your online activities.
A VPN encrypts your data you send or receive online. That means when you connect to the VPN, your internet connection will redirect to the server of the VPN service provider instead of your ISP that masks your IP address – thereby protecting your online identity.
Encryption means creating a tunnel between your device and the internet where your data is transferred into a code which only you and your VPN host can decipher. Even if someone wants to interpret your data, it becomes useless when it reaches the final destination.
Without VPN your data is not encrypted, which means anyone can track your IP address, exposing your online identity and figuring out what sites you browse and the data you send or receive online.
Know that, a VPN only takes care of protecting your online identity and the data you send or receive online. That means it only secures the transmission of your data. The data on your device is still vulnerable to potential hackers and phishing scams for which you require anti-virus software.
A good VPN comes with many benefits. From securing your IP address and online identity to accessing prohibited content and secure data transfer, it covers all. You need a VPN connection if you want your online activities to remain untraced, i.e. the websites you visit, data you send or receive online and the time you spend on each website.
Your online identity remains hidden when you connect to the server of the VPN host. Your actual location remains unidentified and you appear from the location you set on the VPN server. Additionally, most VPN don’t store your browsing history and logs of your online activity. Even if they store it for personal record, they don’t reveal it to any third party.
Besides securing your online identity, a VPN is also used to unlock prohibited content.
In some countries, governments don’t allow their citizens to access a certain content. The content may include adult media or different political and religious views. What VPN does is make you appear as you’re watching the content from another location. It hides your IP address and online identity, giving you access to the prohibited content.
For instance, some exclusive content you watch in US may not watch in UK. There are some UK Netflix series that you cannot watch if you’re located in US. With VPN, you can unlock the exclusive content only by picking the location of that country on the VPN server.
Not to mention, remote work has gone mainstream after Covid-19 hit the world with its wrath. More often, remote workers need access to the company’s servers for important files and documents. Even though most companies take care of their internet connection and personal data, they are not sure if your connection is secure and safe against potential hackers. In that case, companies provide access to the private files with a VPN that acts as a secure bridge between the company and the worker, so no third party can sneak into their personal data.
You’ll find many businesses offering you free Wi-Fi and apps to download when you visit their outlet. Be careful when you connect to their Wi-Fi, because they offer you free internet in exchange of collecting your data. To secure your personal data and remain hidden from the eyes of those retailers, it’s better to use VPN. This way they cannot identify your online activities and you can surf securely as you like better.
There are places where you cannot use 3G or 4G of your mobile network, but you still want some online work done at that moment. You may want to read the news on your cell phone, check important emails from your boss or scroll through your social accounts. Either way, you’re tempted to use public Wi-Fi.
Most public Wi-Fi connections are free to use for anyone, as they are not password protected. But they do come with a risk of potential hacker getting into the details of your personal data as you connect your device with the Wi-Fi. However, if you connect the VPN before performing online activities, no one can identify your location and online presence, giving your data an extra layer of security and peace of mind where you can use the internet anonymously without fear of getting hacked by the hacker.
There are four main types of VPN services.
VPNs are used to develop private and secure connections with the open internet. Mostly personal VPNs are used, however, most businesses and organizations leverage remote access VPNs to allow their member access private files and share and receive data securely over the internet.
Let’s discuss each VPN one by one.
A personal VPN – also known as commercial VPN or consumer VPN – is mostly used by individuals. It connects your device with a VPN server and acts as a bridge between your device and the online activity you want to perform. The personal VPN hides your identify and location by encrypting your data.
There are many reasons you’ll prefer personal VPN. For instance, you can get access to media unavailable to your geographic location. In some authoritarian states like UAE and China, they have developed a national firewalls which block a certain content and make it unavailable to the general public. What VPN does is give access to that content by hiding your web traffic from their monitoring systems.
Simply install the app on your device provided by a VPN service provider. The personal VPNs come with a plenty of servers network to pick from. If your privacy is the primary concern, connect with the local server for the fast speed. However, if you want access to the prohibited content, choose the server where that content is accessible. Connect with the personal VPN and browse the internet like a regular user.
A remote access VPN, also known as client-based VPN, connects your device to the private network as opposed to personal VPN that doesn’t give access to the private network instead it gives access to the public internet by developing extra layer of security with encrypted connection.
Most business owners use remote access VPN to develop a connection between the company’s network and the public Wi-Fi. This way they can leverage all the private files and documents as they would have connected with the office Wi-Fi. The remote VPN keeps the exploring, sending and receiving those files secure and private from the outsider.
Install the client software on your device. Initially, the VPN server checks whether the user is identified and is allowed to use the network. This might involve doing biometric such as using a thumb or entering a password for the identification. Once the authentication process is done, an encrypted tunnel is established between the user’s device and the server, allowing the user to perform online activities like a regular user by protecting the traffic going over the VPN server.
Site to Site VPN is slightly different from the remote access VPN. The remote access VPN allows the user to get access to the private network and use its resources, while Site to Site VPN, on the other hand, combines two networks together located on different sites. For instance, if your company has two offices established on entirely different locations, a Site to Site VPN can be applied to join them in a single network.
Technologies used to implement site to site VPN include: L3VPN, Dynamic multipoint VPN and IPsec tunnel.
IPsec joins two router together to join different networks. However, this process doesn’t suit well for the companies with thousands of sites. In that case Dynamic multipoint VPN is used that joins thousands of sites together using dynamic IP addresses.
Both IPsec and multipoint VPN don’t guarantee consistent performance as they remain on the top of the internet. For global connectivity and good quality, L3VPN is used.
Mobile VPNs are similar to remote access VPNs which means you can access them from anywhere except if you continuously change your location. For instance, when you use remote access VPNs, they give you access to the network, assuming you are located at one location. When you leave that location and get no signal from the public Wi-Fi, your connection with the remote VPN gets lost. In contrast, with mobile VPN that you use on your smartphone devices, your connection with the network remains intact no matter your location is.
Process is similar to the remote access VPN. You require authentication before establishing mobile VPN which require password or biometric process. Once the authentication is done, a virtual tunnel is developed between the VPN server and mobile device. Know that in mobile VPN the connection persists even if your device switches between different network such as public Wi-Fi or cellular network. When the network changes, the IP address will change but the IP address allocated to the VPN tunnel remains the same no matter network you use.
Still reading? Perfect.
It shows you’re really curious to know the key considerations before picking the right VPN for you.
Here are a few things to consider:
Check if the VPN is free. Know that free doesn’t mean it’s totally free. Companies who offer free VPNs cover their cost by running ads and sharing users’ data to third parties.
Do your due diligence to check the security experience of your provider. You should demand online security and privacy and make sure they comply with the rules and regulations they have mentioned in their terms of service and privacy policy.
Even though some reviews are genuine but not all reviews are independent and unbiased. Some VPN companies pay for other websites to publish an excellent review about them. So be critical while picking the right VPN Company for you.
The VPN companies rent servers worldwide. Don’t just pick the service provider with the largest number of networks. Because more networks means the company has less control over them.
That’s all for today. Hope you’re enjoyed reading this article. If you have any question, please ask in the section below. I’d love to help you the best way I can. Thank you for reading the article.
MD What the impact of ai experiences on the modern workflow, life, and UX design is, and how it will change the online user experience.
MT Significant effects of machine learning UX on user experience.
All areas and businesses use AI (artificial intelligence) today without exception. It helps automate processes, boost effectiveness, and even reduce expenses. Digital transformations widely use AI to improve the online user experience and make it smooth and efficient. Undoubtedly, ML (machine learning) and UX designers are in the same boat here and have somewhat the same functions. They both collect data. analyze users’ interactions, and try to predict their behaviors.
Significant achievements in the sphere of artificial intelligence and machine learning contributed to the improvement of user experience. The evolution and rapid development of [https://jatapp.com/services/ui-ux-design/] transform the experience of users in many ways. Gadgets become smarter over the years. AI is a technology that changes a bit in every industry. Let’s see what UX processes can become even more effective thanks to AI and whether UX designers can benefit from it.
Most people do not even suspect that AI is a part of their everyday lives. Some leading corporations worldwide are AI-powered nowadays. Each of your everyday interactions is AI-powered. For instance, Internet prices, search engine results, online transactions, network recommendations, etc. are all parts of your ai experiences.
AI algorithms manage huge volumes of data to interact with various companies. Artificial intelligence removes all learning restrictions with the help of this complicated network. People, in turn, use these algorithms and data to reach quite curious goals. For instance, some researchers study how AI can be used to automatize machine learning ux for users.
Different methods are used to learn users' moods or review classifications. These experiments are partially successful but they bring really effective and significant results.
Artificial intelligence is used in every sphere of modern life even if you do not suspect it. AI UX design has penetrated every corner of users’ beings. AI enables thinner user interfaces, automation, modular and smarter design systems, data analysis, visual effects, enhanced UX processes, wireframing, A/B testing, and UX design itself. Let’s see how exactly artificial intelligence technologies are used in every separate sphere.
AI in recruiting is very widespread today. HR services have specific apps that can facilitate the process of choosing and employing personnel. Some human resources specialists doubted the efficiency of AI since the selection results could be too predictive. The effect was the opposite though. Tags and keywords improve the usage of these apps. It means that AI can make human resources offers that can not even be noticed by human specialists.
Although AI is still in the development stage, it already proved to offer much cheaper alternatives to employment. It allows one to spot candidates who could never work in this field but possess the necessary skills and knowledge for the position under discussion. These skills could be crucial for a specific company. Since these candidates do not have experience in the necessary field, their salaries will be lower than those of more experienced workers.
The most popular human resources software used worldwide nowadays is Seedlink, Amazon, and Isaak. The software is yet to be developed but it is going to bring more benefits to the sphere and improve the employment processes.
When users receive emails regarding the latest offers and sales, etc., AI plays a huge role in it. Artificial intelligence learns and reads using algorithms. It boosts users' engagement not only based on what they search for but also on what they interact with. Let’s say, a user clicked the link in the received email to view or purchase certain goods. AI remembers it and delivers more similar emails to the same user.
However, AI technologies are not limited to emailing only. It allows users to purchase more effectively when it is necessary. Artificial intelligence allows everyone who needs certain information to access it. People stop wasting time scrolling through unnecessary information. Remote and online purchases become perfect thanks to an AI user experience course.
Although AI is associated with advanced and complicated algorithms, it is still widely used in certain forms in the sphere of manual labor. For instance, in production. All sectors of food and drink production involve innovations that make the participation of AI possible in all working processes. Robots even make coffee steadily.
Moreover, AI is widely applied in healthcare and medicine. It allows surgeons and other workers to use different helpful tools. Health checkups and understanding body conditions are two main applications of artificial intelligence in medicine. Different apps and tools help in learning the language and improving speech. We use smart techs to learn to play musical instruments, etc. Even the arts are full of AI technologies.
Behind every platform, there is AI that sends you content offers. Sites that use search-log data apply this opportunity, for example, Netflix or YouTube. With the help of AI, they offer users different movies they could be interested in based on their data. The same technologies are used by Spotify or Apple Music to offer music to listen to.
To improve user experience, engineering stepped into the path of rapid technological progress. Chatbots became some of the biggest innovations. Client support systems use chatbots to offer their customers round-the-clock access to their assistance. AI bots can solve general issues and assist in data search.
For better customer service, more profound robots and AI technologies appear but it doesn’t mean that humans will stop working. It will just facilitate the work of people and make it of better quality. Instead, they can focus on more important tasks and pay more attention to details. It is also very cost-effective since it doesn't require hiring different employment groups to serve clients in different time zones.
Users interact with artificial intelligence technologies daily. Robots help send personalized emails and brew coffee. Everyone benefits from the usage of AI in every sphere of life. Customer support, medicine, education, and the rest of the fields improve with the help of UX and AI cooperations. People are worried about whether AI will fully replace humans. However, these concerns are useless because they allow us to save time, and money and prevent human employers from burnout increasing their productivity at the same time.
The importance of big data analytics has been increasingly recognized in recent years. This is because big data is a potent tool that can assist organizations in making better decisions, identifying and solving problems, and improving their operations. This article will discuss some of the benefits of data analytics and provide a few examples of how it can be used in business.
Data analytics is crucial because it allows businesses to collect massive amounts of data never before. This metadata can then be used to create insights that were previously impossible to obtain. Data analytics has the potential to change the way businesses operate in ways that are far-reaching and impactful.
With much data available at our fingertips, it's now easier for organizations to make informed decisions about their operations. This means businesses can make smarter choices about which products to produce, which employees to hire, and which marketing campaigns to pursue.
It is a technique that can be used to analyze large amounts of data to gain insights that can be used to improve business processes. Organizations can improve their operations by understanding big data by identifying and resolving issues early, optimizing resources, and increasing profits.
It can also be defined as using big data to improve business processes and decision-making. The key to success with this data analytics is understanding how to use the data to enhance your business. Here are tips for getting started with data analytics.
The first step in any data analytics project is to gather the DataData you need. This may include collecting customer information, monitoring financials, or tracking product sales. Once you have the data, you need to identify what you want to learn. This may involve analysis of trends, comparisons between different groups of data, or predictions about future outcomes.
After collecting and analyzing the data, you need to understand it. This involves looking at the data in terms of dimensions (such as size, location, and time) and then sorting and grouping it in ways that make sense. You can also use machine learning algorithms to predict future behavior based on past behavior.
In contrast to the older model, which depends on pre-defined structures for data storage and retrieval, data analytics relies on an open architecture that allows for the analysis of any data.
Data analytics applications can improve decision-making: Businesses can better understand customer behavior and what drives purchase decisions by collecting massive amounts of data. This information is then used to improve marketing campaigns and product offerings.
Can help speed up the processes: By understanding the patterns and trends in large datasets, businesses can speed up decision-making processes and improve overall efficiency. This can help companies stay ahead of their competition and remain competitive in an ever-changing market landscape.
When it comes to analytics on big data, the benefits are real-time. With the right tools and approach, businesses can glean insights in near-real-time, making decision-making quicker and more accurate. Here are four key benefits of this data analytics:
With this data analytics, companies can track customer interactions in near-real-time and identify problems quickly. This allows them to provide a better customer experience by quickly resolving issues and providing improved service. Furthermore, it will enable businesses to target marketing campaigns more effectively, as they can see which customers are most likely to respond positively to a particular offer.
Extensive data analytics can help businesses improve their productivity and efficiency by identifying patterns and trends in their data. For example, suppose a company is manufacturing products. In that case, extensive data analytics can help them determine which parts are being made in the production line, leading to increased efficiency and decreased waste.
By understanding customer behavior and preferences, businesses can increase revenue by tailoring their offers specifically to those who have shown an interest in their products or services. Additionally, they can use predictive modeling techniques to make predictions.
Real time data software has the potential to provide real-time benefits for businesses. By understanding and analyzing large amounts of data, companies can improve their operations and dramatically reduce the time it takes to make decisions. Here are five key reasons why massive data analytics is so important:
The big data analytics revolution is here. By 2025, the world will generate more than 2.5 quintillion data points. This abundance of data will require organizations to adopt new, innovative ways of analyzing and understanding data to make intelligent decisions.
The benefits of this analytics are clear: By enabling organizations to analyze large amounts of data more quickly and efficiently, data analytics can help identify trends and patterns that would be difficult or impossible to detect using traditional methods. Additionally, it can help businesses improve their operations and deliver better customer experiences by providing insights into customer behavior and performance.
In order to use certain fasteners, you may need to drill holes. Counterbored holes are ideal for this because their flat bottoms allow a flat head socket cap screw to sit flush against the board. To make a counterbored hole, you must first determine the sink and bore sides, as well as the shaft plating, whether it is plated or not. Counterbored holes are not always the same shape as their drilled counterparts.
A counterbore is a hole formed by drilling a larger diameter hole into an already existing hole. This hole is typically drilled to a diameter of one-quarterquarter inch or greater. Counterbores are useful for keeping workpieces together. They're also useful in manufacturing applications where the size of the hole is important. The counterbore size can be adjusted to accommodate the fastener size.
While wood and metal countersinks have similar effects, they serve different functions and serve different purposes. Wood countersinks are commonly used in plastic and wood parts for screws, whereas metal countersinks are used for bolts. The primary distinction between wood and metal countersinks is the type of connection and the strength of the counterbore. When it comes to making holes in printed circuit boards, the differences between the two are more pronounced. As a result, before deciding which one to use, you should carefully assess your situation.
You may be wondering, "What is a Countersink?" Here are some details. Countersunk holes are deeper than standard holes, so the screw head will sit below the surface. This allows the screw to go all the way through the wood without breaking it. This helps to keep the board's surface from warping or deforming. This is especially true when working with finer materials such as brass. However, before purchasing a countersink bit, read this article to understand what it is and why it is required.
When using screws to join projects, a countersink bit is required. It enables the screw to penetrate beneath the surface of board products, allowing for a wide range of finishing options. Countersink bits are available at local hardware stores and can be used with most drills. Once you've determined the proper size, simply switch the drill to its drill function. This will allow the countersink bit to properly perform its function.
Countersinking is an important step in optimizing the performance of your PCB. It makes a conical hole that matches the angle of the screw and improves PCB performance. Countersink angles of 60, 82, and 90 degrees are the most common. It is best to purchase a countersink PCB that has been certified by an authoritative organization. For example, if the manufacturer has a RoHS certification or adheres to IPC standards, it is likely to produce high-quality products. A well-organized website is also a good sign.
Both types of holes have different diameters. They have the same shape but differ in depth and shape. The difference is in the cutter used to make them. Countersinks are more commonly used in woodworking and thin sheet metal applications. Counterbores are used in construction, automotive, and architecture. The differences between the two types of holes are significant, and they should be understood before using either type of hole.
The difference between a countersink and a counterbore is that the former produces a round hole while the latter produces a cylindrical hole. Forstner bits are used in counterboring tools to create precise pilot holes. They are used when a round hole is desired but not always when a smooth finish is required. For a T-shaped fastener, a countersink is often preferable.
While countersink holes are more commonly used in small devices, counterbore holes are used in larger electronics and industrial settings. Countersink holes are typically safer to use and make the installation of small electronics easier. Countersink holes also fit better in tight spaces than counterbored holes, which is why they are used in many types of electronics and washers. When tight fitting is a priority, countersink and counterbore holes are the best choice, but check the manufacturer's manual for more information.
When using a countersink or counterbore, keep in mind that the screw or bolt is not set at the top of the workpiece. The screw or bolt head remains beneath the workpiece's surface. A counterbore is a more secure method of creating flat holes that is commonly used in woodworking and plastics. A counterbored hole is usually larger than the screw head.
When a fastener is tapered, it requires a countersink. The countersink ensures that the fastener is fully inserted, ensuring a strong connection. Aside from the aesthetic benefits of a countersink, it also reduces the risk of a cut or tear to the skin or clothing. Countersinks are typically less expensive than countersinks, so you must choose between the two.
Countersinks and counterbores differ in size and shape, as previously stated. A countersink has a flat surface for exposed bolts and nuts, whereas a counterbore has a recessed portion. The dimensions of countersink and counterbore holes are determined by the fastener's size and diameter. A countersink can also be a shape, which requires a sketch and the placement of holes.
When using a countersink, drill on the opposite surface of the mating piece. A countersink helps the parts fit together properly and removes burrs from drilling and tapping. Countersinks can also be used to make a shallow hole in wood for coach bolts. The coach bolt's head fits into the shallow hole, increasing structural lifetime. It is important to note that the distinction between countersink and counterbore is subtle.
There are numerous PCB applications that necessitate the use of holes. One of these applications involves drilling a countersink or counterbore hole. This allows the hole to be flush with the PCB's surface. The countersink hole is more complicated than the counterbore hole because it is designed to fit a standard screw with a flat head. It does, however, allow the PCB to be flush with a board or device.
While sinkholes are often preferred, countersink PCB is often the best choice for increasing functionality. You can add components without interfering with the functionality of your design. The countersink hole facilitates drilling without damaging the PCB. Furthermore, you must drill it correctly to avoid damaging the PCB. Before drilling, you must determine which side of the PCB to drill. This is determined by the location of the components.
When looking for a manufacturer for your PCBs, look for one that uses standard materials and has plenty of storage space. Look for a manufacturer who has been certified by reputable organizations such as the IPC or RoHS. A manufacturer with standard customer service and a well-structured website will be worth your time and money. There are numerous advantages to using countersink and counterbore PCB applications.
There are numerous types of countersink, and plated holes are a common application for both. The surface finish you choose can have an impact on the appearance and efficiency of the countersink hole. For example, a finished surface finish can make the hole appear smaller or larger than it is. If you want the countersink to be plated, you must consider the surface finish before purchasing.
Do you have a PCB with a countersink or a corresponding counterbore hole? These holes are intended for use in small or limited-space devices. You can use these holes to insert socket screws into the board. They also make it simple to drill the PCB's surface without destroying the design. If you're not sure what you're doing, keep reading to learn how to properly install your PCB.
Using a two-drill method, you can drill a countersink hole without a countersink bit. This method is dependable, but it will never yield a perfectly square hole. Before drilling your PCB, wrap tape around the bit to keep it from going through the materials. Drill a larger drill bit through the board's material and insert the screw into the hole.
A countersink hole is used in devices with a very tight fit and is the best choice for small devices. A counterbore hole is used when a cylindrical screw cannot fit in a small enough hole. It is also used in washers and other electronic components. Before committing to a counterbore hole, check with your PCB supplier to ensure that it is countersunk.
In general, the price of a countersink PCB can vary. The cost of PCB materials, copper thickness, and surface coating will all have an impact on the price. The quality and service of the PCB manufacturer are critical for PCB reliability. PCBMay can offer high-quality, error-free PCB Assembly services. Our website could be well-organized and include information about the manufacturer. Consumer reviews may provide information on the manufacturer.

Generally, the hardware in this situation has a shorter lifespan than the software. With time, the hardware becomes harder to maintain. Such a system will either be too complex or expensive to replace. For that reason, it continues operating.
Legacy software and legacy hardware are often installed and maintained simultaneously within an organization. The main changes to the legacy system typically only replace the hardware. That helps to avoid the onerous requirements management of the software certification process.
Legacy systems operate in a wide range of business organizations, such as banks, manufacturing, energy companies, hospitals, and insurance companies. You can also find them in the defense industry, among other multifaceted business organizations.
Only companies born in the digital age don't face the problem of chronic legacy system pains, i.e. the distress of a lack of digital transformation. Legacy systems can involve unbearable complexity, mismatched skills, lack of innovation, bureaucracy, and so on.
Legacy systems form in organizations for many reasons. First, compliance issues and a rollout are often challenging to carry out all at once. There may be an ongoing project that needs the old system. There are also instances where decision-makers don't like change.
However, the shortcomings of operating an old system are annoying and can also cause severe damage to the company. The pains of operating an old system include:
Legacy systems can include the 'Stop and Start' strategy. There are also long static periods or unchanging business, which was the mainstream way of running business operations throughout the industrial age. This means systems have a short period to make and adapt to any necessary changes, while business stops and waits for the wave of essential changes to finish.
The world doesn't work like this anymore. Intermittent changes allow organizations with old systems to persist up to the next phase of evolution.
Fortunately, there is an alternate option called lean IT. The model advocates for making positive changes and continuous improvements and is aimed at avoiding getting stuck in waiting mode.
The lean IT model is well suited to data-oriented and digital systems, and helps discourage the myopic views that legacy systems foster in the first place.
Legacy systems can pose several data security problems in an organization. Security is a prominent feature of the lean IT model. Continuous improvements and positive changes help to curb the latest threats. Old systems, because of their age, struggle with this.
Legacy systems may pose various challenges when fixing specific vulnerabilities, due to their large and inflexible nature. Making a fix in legacy systems can face delays because developers find it challenging to create one. Also, creating a repair is often not on the development team’s priority list. As a result, the fix ends up being very expensive.
Old systems can enter into a period where there is a danger to the organization due to their outdated security measures.
The digital age has created tremendous opportunities, including those related to changing a company's way of operations to benefit its users. Businesses that don't have legacy systems find that when technology moves, the industry can move with it. They are ready to use any new generation that comes out and are prepared to download and install any new application that becomes popular.
Under these conditions, challenges can mount for a company stuck with an old system. Legacy systems have restrictions on using new applications. Businesses that have many customer interactions can encounter serious challenges.
Customers often go for features on the latest applications available in this digital era, such as Instagram and Windows 10 updates. Both of these have chatting options that legacy systems can't enable. This is very much a missed opportunity.
It may seem like legacy systems would be less expensive to maintain. However, that connotation changes over time, and circumstances often prove cost to be a pain point. Support and software updates for legacy systems are often much more expensive than current models, whose support and updates are always ready for seamless implementation.
The reason behind the additional maintenance cost is that knowledgeable software developers are hard to find. It involves a lot more work for software developers to offer the necessary continued care and updates for a legacy system than a current system.
A legacy systems compatibility issue affects all users. We’re talking about the customers and business partners, suppliers, team members, and other associated users.
The legacy system will support file and data formats up to a certain point. But over time, these formats advance over and beyond what the legacy system can handle.
The evolution of support formats only takes a couple of years. In this event, the business will be stuck and experience pain points from using forms the customers or partners are no longer willing to use.
A company without legacy problems will adapt to successful implementation fast, aiming for better collaborations among users and team members. They also avoid waste in IT operations. Therefore, the future of the company's business remains adaptable.
Legacy systems are often full of lurking, untested problems. Support is often difficult to come by, leading to frustrating support interactions.
Customer support is critical, especially when you have large data sets or tight deadlines. Modern software development techniques make it easy to release and access track records. System data storage matters a lot to the users, so data storage and accessibility are key features in new systems that also come in handy when support is necessary.
Look at the IT team members' psychological aspects for a moment. What does operating a legacy system say to the workforce? It signals that it's okay to work with an old system on one end while putting off addressing worries until later. The system solutions from the past are still working.
But an organization should not encourage this view in their employees, especially when training employees in new skills.
The method may still function, but it will be a massive liability for connectivity and security. Legacy systems also reduce productivity, lower team members' morale, and repel some of the best talents. Employees with first-hand experience in new technology want to hold to that and have no interest in learning old systems.
"If it's not broken, don't fix it" is the IT professional's general attitude. Though it does not stem from any bad intentions, it can cause a company severe problems down the road.
Legacy systems tend to be clunky, extensive, and very proprietary. Changing or customizing them poses a serious challenge. But modern IT professionals prefer to use the latest techniques and have no interest in mastering old systems.
Some organizations' software and hardware needs are different from other companies. Therefore, they need to build their custom software and hardware. New systems have smaller parts that make them flexible and easy to adopt. Specialized needs are no excuse for retaining legacy systems.
High-regulated industries have difficulty catching up with technology because of their complex systems. You may feel your company has outgrown its requirements management software, and you’re not alone.
The line between software and hardware becomes more and more blurred, and innovations are occurring faster than ever before. Requirements management providers may not supply the right software that matches the users' goals, regardless of the notable reputation or how complex the software is. That can create severe problems that affect productivity.
Here are some common methods for how to work your way out from a legacy system into something much more helpful for yourself and your customers:
Highly regulated industries interact with many different stakeholders and players, which is good for their business. It is essential to value the input of the various roles and skill sets.
But problems can arise if one of these users doesn't know how to use your requirements management software. Stakeholders bring their benefits to the company, but interfering with the system can be a recipe for compliance disaster.
To avoid such problems, look for software that flows with several roles and is seamless. Also, make sure your software integrates user-friendly traceability. Every user on the project needs to see the progress from beginning to end. This will prevent use problems from becoming a lasting problem and hindering productivity.
Missing deadlines happen in many organizations. A team member needs to provide feedback but fails to do so on time. It could have been sent via email, Google, or Word document that someone didn’t know to monitor. Whichever means were used, the model of collaboration in place failed.
Review processes are quite complex these days, and you need collaboration software that sets clear intentions for the users. Real-time notification and editing will help keep team members on the truck.
Opt for a requirements management tool that prompts the next step to avoid falling into the trap. The requirements management software will help to prevent blame games - and it’s an excellent reason to suggest upgrading away from the legacy system altogether.
There may be instances where you want to carry out an essential process through the legacy system - but you are somehow locked out. You may have challenges finding the person who manages the system access rights and can get you back in the loop.
The situation can be frustrating and pose significant risks to the company, since one can attempt to break into the system for a couple of hours. This also wastes time. The desire to provide timely feedback with confidence is thwarted, which goes against the first intention of collecting the data.
The right requirements management tool should provide continuous data collection and growth. To achieve this, it should be open, accessible, and intuitive. The stakeholders will get motivation and provide constant input and collaboration, which is vital in keeping up with breakneck innovation.
When an upgrade notification pops up on our screen, it’s normal to get skittish. There was once a very real fear of losing essential data and vital information with any kind of system update.
But this fear has dissipated with the advent of the cloud. A company no longer has to fear upgrading and fixing software requirements. It’s necessary to improve the security requirements and access some of the latest features.
It's crucial to have a system that adapts quickly to update requirements. When purchasing legacy software, consider the opportunity costs of not upgrading and encountering the headache of being locked out of various unsupported platforms.
As part of evaluating your current system, investigate data storage safety during software development. Find out from existing customers how well your system releases the accurate document.
Whatever system you choose will be around for a long time, so you will need to measure your predicted needs from the vendor. You will be putting some of your crown jewels on the system you want to buy. They need to be safe.
We live in an age with the most innovative and disruptive products available to more people than ever. We have ultra-fast electric cars, self-piloted spaceships, and lifelike prosthetics. We also have some of the brightest minds toiling to help propel us into the future.
This means the regulatory environment now is more stringent, especially on public safety and the marketplace demands. There is a need to have a team ready to meet the ever-increasing demands of compliance.
To be on the safer side, you need to put in place a collaborative infrastructure to keep the team organized and detect mistakes of disconnected persons in real-time. The future of your company depends on it.
Migrate. This allows the business to perform critical processes immediately. Legacy software may not be flexible enough to allow the expected modification. Also, your old system may not offer its users the right results. Legacy migration can be the better choice in this case.
The other option is extension. You may not need to replace a legacy system that still performs its core functions (especially if it still has some years of warranty remaining). Despite that, you can still modernize it by extending its capabilities.
Try to make concrete and practical recommendations on how to make the legacy system better. Provide evidence on how the improvements will lead to better performance. You may change minds by presenting realistic situations where the legacy system can still be helpful in the future with just a few additions.
Additive manufacturing is the technique of production that 3D printers use to create physical objects. Additive manufacturing is the manufacturing process in which you create an object from scratch by directly layering the raw material.
This technique is different from others because it does not create waste like subtractive manufacturing. It does not require manual effort and time like the formation process where you add force to a material to shape it, and it does not require tools and molds like casting to produce a functional product.
In conclusion, additive manufacturing requires no tools, has no waste, and needs zero cutting and complex procedures.
There are various types of additive manufacturing in the market. All of these processes are suitable for their respective fields and functions. A production house can use one of these techniques to create its design.
After the design is complete, cure the product in an oven to enhance its mechanical properties. The cast of the product comprises a water-breakable mixture. Therefore, in the third step, soak the mold in water. It will degenerate, and you can finish your product in the last step for further use.
This process is rapid, and your production, which took weeks, now only takes a few days.
Fusion deposition modeling is a typical process of manufacturing in an additive process. A domestic printer uses this process to create designs. This printer is easy to use as you need to fill the printer with filament from one end, and it will produce your design on the other end.
This process needs a design, the software cuts the design into thin digital slices, and once the data is in the printer, it will create the product automatically. It may be easy to use, but large-scale industries do not prefer it for its poor finish and fragile material.
The process of Stereolithography is unique as it uses photosensitive resin to solidify the design out of liquid polymer. It is a precise way of creating objects from resin, and it does not require as much time as other printing methods. The UV rays cure the liquid polymer on top of the layers. It creates an illusion of an object being born from the liquid.
The laser sintering method is dangerous in public places, but it is practical for enormous industries. It uses refined metal powder as raw material. The machine uses a laser to create a solid object from this metal dust. The printer does have a container box for metal powder but inhaling this powder can be dangerous.
NASA and other mechanical corporations use this technique to build parts for air crafts, planes, cars, and other automobiles. If the production house follows all the SOPs, this method is one of the fastest methods of creating parts.
The poly jet method is a mixture of FDM and SLA printing. The machine uses thin layers of resin and layers are like a filament, and the UV light instantly cures the resin in place. This technique is valuable for rapid prototyping, fixtures, and creating functional moving parts.
Multiple applications and implications of 3D printing suggest that it has revolutionized the world. 3D printing has minimized the connection between production and consumption. A consumer can directly produce a design in a short time. The time for a product to reach the consumer has drastically reduced.
The emergency disaster zone fixtures are possible with the help of instant 3D printing. It also inspires the younger generation to create and practically use their theoretical knowledge. It has inspired the world to connect virtual reality to physical reality. And all of this is just the beginning of what 3D technology has to offer.
To perform jumping in the ladder logic program, two instructions are together, as shown in Fig. 1. The first instruction is JMP which tells the PLC you need to jump from where the jump instruction is to where you find the LBL instruction.
Fig. 1: JMP and LBL instructions
Now how to know the label to whom you want the program execution to go or jump? Well, that is an excellent question, and the answer is that you should specify the label name as a parameter of jump instruction and the label instruction. Therefore, you can notice, my friends, if Fig. 2, the JMP and LBL instructions have a question mark denoting you should specify the label name, which is the next station to programme execution.
Fig. 2: Jump and Label instruction showing the label name above of them
Now friends, let us see how jump and label instructions work together, as shown in fig. Three depicts a straightforward example of ladder logic in which JMP and LBL instruction work together, referring to the same label Q2:0. In this example, if input contact I1/0 is activated, JMP instruction will take the execution where the Q2:0 label “LBL” instruction is. As a result, the rung 001 has been bypassed.
Fig. 3: ladder logic example for jump and label instructions
How about going with a situation where we need to employ JMP and LBL instruction? Yes, in the example shown in fig. 4, You can notice here in this example. There are a couple of motors and for these motors. We need to. Use Siri. The command of the jump. And in combination with the uh label instruction. 2. Let some motors work in one scenario. And in another scenario, we will let some of these motors worworkd the others are not working. So you can imagine if you are working with Couples of pumps and want to run all pumps together in one scenario, so you do not activate the JMP command. But, in another scenario, if you’re running some of these pumps. So what we are going to do here in this example is to activate the JMP command to bypass some of these pumps, which are between the JMP and LBL commands.
Fig. 4: a real example of jump instruction
Figure 5 depicts the execution of the sample program that demonstrates JMP instruction. This case shows what happened in the first scenario example. If we do not activate jump instruction in rung 3, then all motors 1,2,3,4,5,6 and 7 will run based on the status of their firing contacts which are I:0 0 to 7, respectively. And the program execution continues running other motors after the JMP as it is not activated by touch I:0 3.
Fig. 5: test when JMP is not activated
On the other hand, Fig. 6 depicts the second scenario when activating JMP instruction by contact I0:3 at run number 3. By activating the jump command, We can notice only the motor before jump instructions are running based on their command contacts when the pumps in between jumps and label commands are bypassed, and the other engines after label instruction are running. So motors 1,2 and 3 are running, motors 4,5 and 6 have been ignored by activation of jump command instruction, while motor seven is running, which is at label command.
Fig. 6: test when JMP is activated
LinkedIn is a powerful social media platform for businesses of all sizes. It provides an opportunity to connect with a larger audience, build relationships with potential customers, and create brand awareness. But promoting your business on LinkedIn is not as easy as you might think. For one, LinkedIn is a professional network, which means that users are not always looking to be sold to. Secondly, LinkedIn’s algorithm favors content that is educational and informative over content that is promotional.
So how can you promote your small business on LinkedIn in a way that will reach your target audience and help you achieve your business goals? Here are the top LinkedIn marketing strategies that you can use to expand your small business.
If you want to reach your target audience on LinkedIn, you need to share content that is interesting and engaging. This means creating content that educates, informs, or entertains your readers. For example, if you're a construction company, you could share articles about the latest industry trends, tips for remodeling your home, or interesting case studies.
The key is to make sure that your content is relevant to your target audience and provides value. If you're not sure what type of content to create, take a look at the content that your competitors are sharing. Chances are, their content will give you some ideas.
However, that doesn't mean you should write walls of words - avoid that at all costs. No one wants to read an essay on LinkedIn. Keep your posts short and to the point. Use images, infographics, videos, and LinkedIn banners to break up your text and make your content more visually appealing.
You can't just start posting on LinkedIn with a blindfold on now, can you? You need to know who you're targeting first.
Creating personas for your target audience is a great way to get to know them better. Once you've created personas, take a look at where your target audience hangs out online. What type of content do they consume? What are their interests?
You can use this information to create content that appeals to your target audience. For example, if you're targeting millennials, you might want to create content that is relevant to their interests, such as entrepreneurship, travel, or personal development.
One of the best ways to promote your small business on LinkedIn is by creating a company page. Your company page is like a mini-website on LinkedIn, and it's a great way to showcase your products or services.
When creating your company page, make sure to include a strong headline, an engaging description, and relevant images. You should also take advantage of LinkedIn's SEO features by including keywords in your page content.
Once you've created your company page, start sharing content that will interest your target audience. This could include blog posts, product information, case studies, or even company news. You can also use your company page to run LinkedIn ads. LinkedIn offers several ad formats that you can use to promote your business, and they're a great way to reach a larger audience.
Your LinkedIn profile is one of the most important tools in your LinkedIn marketing arsenal, so optimizing your LinkedIn Profile is essential. It's your chance to make a good first impression, so make sure you're putting your best foot forward.
Start by optimizing your headline and summary. These are the first things people will see when they visit your profile, so make sure they're attention-grabbing and relevant. Include keywords that describe your business or industry, and make sure to mention your most important selling points. Your headline and summary are also a great place to showcase your personality.
Next, take a look at your profile photo. Is it professional and polished? If not, consider changing it to something that presents you in a positive light. Finally, take some time to update your work experience and education section. Include any relevant information that will help you stand out, such as awards or publications. By optimizing your LinkedIn profile, you'll be sure to make a good impression on potential customers and clients.
Another great way to reach your target audience on LinkedIn is by joining relevant groups. There are thousands of groups on LinkedIn, covering just about every topic imaginable. And chances are, there are several groups that would be a good fit for your business.
For example, if you're an apparel retailer, you could join relevant groups on LinkedIn to promote your business. These groups could include fashion professionals, small business owners, or even general interest groups.
When you join a group, make sure to participate in the discussion and add value to the conversation. This will help you build relationships with other members and position yourself as an expert in your field.
You can also use LinkedIn groups to collect leads. Many groups allow members to post their contact information in the group description. This makes it easy for you to get in touch with potential customers.
Did you know that you can use LinkedIn to generate leads? It's true! LinkedIn offers a feature called Sponsored InMail, which allows you to send messages directly to your target audience. Normally, on the free plan, you can't send priority messages to anyone. Therefore, InMail is a great way to promote your products or services, and it's an especially effective lead generation tool.
Sponsored InMail is a great way to reach out to potential customers and promote your products or services. You can use it to offer discounts, announce new products, or even invite people to events.
To get started, simply create a Sponsored InMail campaign and target your ideal customer. LinkedIn will then match your message with the right people, and you'll start seeing results in no time. Just make sure your message resonates with your target audience. Otherwise, you risk having it perceived as spam.
While the above marketing strategies will work like a charm when it comes to promoting your business and gaining new customers, bear in mind that every business is different and has a different target audience. Therefore, it's important to experiment with different strategies and find the ones that work best for you. Identifying the right marketing mix for your business is what you should be aiming for.
For example, you could use LinkedIn ads to reach out to your target audience if you're looking for immediate results. Or, if you're trying to build long-term relationships with potential customers, focus on creating a strong company page and sharing high-quality content.
Also, don't forget to harness the power of SEO! In simple words, SEO makes your content more visible in LinkedIn's search results, which means more people will see it. You can do this by optimizing your LinkedIn profile and company page for keywords, and you'll surely gain more traction on your LinkedIn profile.
Thank you for joining us for yet another session of this series on Raspberry Pi programming. In the preceding tutorial, we created a pi-hole ad blocker for our home network using raspberry pi 4. We also learned how to install pi-hole on raspberry pi four and how to access it in any way with other devices. This tutorial will implement a speech recognition system using raspberry pi and use it in our project. First, we will learn the fundamentals of speech recognition, and then we will build a game that uses the user's voice to play it and discover how it all works with a speech recognition package.
Here, you'll learn:

Are you curious about how to incorporate speech recognition into a Python program? Well, when it comes to conducting voice recognition in Python, there are a few things you need to know first. I'm not going to overwhelm you with the technical specifics because it would take up an entire book. Things have gone a long way when it comes to modern voice recognition technologies. Several speakers can be recognized and have extensive vocabulary in several languages.
Voice is the first element of speech recognition. A mic and an analog-to-digital converter are required to turn speech into an electronic signal and digital data. The audio can be converted to text using various models once it has been digitized.
Markov models are used in most modern voice recognition programs. It is assumed that audio signals can be reasonably represented as a stationary series when seen over a short timescale.
The audio signals are broken into 10-millisecond chunks in a conventional HMM. Each fragment's spectrogram is converted into a real number called cepstral coefficients. The dimensions of this cepstral might range from 10 to 32, depending on the device's accuracy. These vectors are the end product of the HMM.
Training is required for this calculation because the voice of a phoneme changes based on the source and even within a single utterance by the same person. The most probable word to produce the specified phoneme sequence is determined using a particular algorithm.
This entire process could be computationally costly, as one might expect. Before HMM recognition, feature transformations and dimension reduction methods are employed in many current speech recognition programs. It is also possible to limit an audio input to only those parts which are probable to include speech using voice detectors. As a result, the recognizer does not have to waste time studying sections of the signal that aren't relevant.
There are a few speech recognition packages in PyPI. There are a few examples:
NLP can discern a user's purpose in some of these programs, which goes beyond simple speech recognition. Several other services are focused on speech-to-text conversion alone, such as Google Cloud-Speech.
SpeechRecognition is the most user-friendly of all the packages.
Voice recognition necessitates audio input, which SpeechRecognition makes a cinch. SpeechRecognition will get you up to speed in minutes rather than requiring you to write your code for connecting mics and interpreting audio files.
Since it wraps a variety of common speech application programming interfaces, this SpeechRecognition package offers a high degree of extensibility. The SpeechRecognition library is a fantastic choice for every Python project because of its flexibility and ease of usage. The APIs it encapsulates may or may not be able to support every feature. For SpeechRecognition to operate in your situation, you'll need to research the various choices.
You've decided to give SpeechRecognition ago, and now you need to get it deployed in your environment.
Using pip, you may set up Speech Recognition software in the terminal:
$ pip install SpeechRecognition
When you've completed the setup, you should start a command line window and type:
Import speech_recognition as sr
Sr.__version__
Let's leave this window open for now. Soon enough, you'll be able to use it.
If you only need to deal with pre-existing audio recordings, Speech Recognition will work straight out of the box. A few prerequisites are required for some use cases, though. In particular, the PyAudio library must record audio from a mic.
As you continue reading, you'll discover which components you require. For the time being, let's look at the package's fundamentals.
The recognizer is at the heart of Speech Recognition's magic.
Naturally, the fundamental function of a Recognizer class is to recognize spoken words and phrases. Each instance has a wide range of options for identifying voice from the input audio.
The process of setting up a Recognizer is straightforward. It's as simple as typing "in your active interpreter window."
sr.Recognizer()
There are seven ways to recognize the voice from input audio by utilizing a distinct application programming interface in each Recognizer class. The following are examples:
Aside from recognizing sphinx(), all the other functions fail to work offline using CMU Sphinx. Internet access is required for the remaining six activities.
This tutorial does not cover all of the capabilities and features of every Application programming interface in detail. Speech Recognition comes with a preset application programming interface key for the Google Speech Application programming interface, allowing you to immediately get up and running with the service. As a result, this tutorial will extensively use the Web Speech Application programming interface. Only the Application programming interface key and the user are required for the remaining six application programming interfaces.
Speech Recognition provides a default application programming interface key for testing reasons only, and Google reserves the right to cancel it at any time. Using the Google Web application programming interface in a production setting is not recommended. There is no method to increase the daily request quota, even if you have a valid application programming interface key. If you learn how to use the Speech Recognition application programming interface today, it will be straightforward to apply to any of your projects.
Whenever a recognize function fails to recognize the voice, it will output an error message. Request Error if the application programming interface is unavailable. A faulty Sphinx install could cause this in the case of recognizing sphinx(). If quotas are exceeded, servers are unreachable, or there isn't internet service, a Request Error will be raised for all the six methods.
Let us use recognize google() in our interpreter window and see if it works!
Exactly what has transpired?
Something like this is most likely what you've gotten.
I'm sure you could have foreseen this. How is it possible to tell something from nothing?
The Recognizer function recognize() expects an audio data parameter. If you're using Speech Recognition, then audio data should become an instance of the audio data class.
To construct an AudioData instance, you have two options: you can either use an audio file or record your audio. We'll begin with audio files because they're simpler to work with.
To proceed, you must first obtain and save an audio file. Use the same location where your Python interpreter is running to store the file.
Speech Recognition's AudioFile interface allows us to work with audio files easily. As a context manager, this class gives the ability to access the information of an audio file by providing a path to its location.
This software supports various file formats, which include:
You'll need to get a hold of the FLAC command line and a FLAC encoding tool.
To play the "har.wav" file, enter the following commands into your interpreter window:
har = sr.AudioFile('har.wav')
with harvard as source:
audio = r.record(source)
Using the AudioFile class source, the context manager stores the data read from the file. Then, using the record() function, the full file's data is saved to an AudioData class. Verify this by looking at the format of the audio:
type(audio)
You can now use recognize_google() to see if any voice can be found in the audio file. You might have to wait a few seconds for the output to appear, based on the speed of your broadband connection.
r.recognize_google(audio)
Congratulations! You've just finished your very first audio transcription!
Within the "har.wav" file, you'll find instances of Har Phrases if you're curious. In 1965, the IEEE issued these phrases to evaluate telephone lines for voice intelligibility. VoIP and telecom testing continue to make use of them nowadays.
Seventy-two lists of 10 phrases are included in the Har Phrases. On the Open Voice Repository webpage, you'll discover a free recording of these words and phrases. Each language has its own set of translations for the recordings. Put your code through its paces; they offer many free resources.
You may want to record a small section of the speaker's speech. The record() method accepts the duration term parameter, which terminates the program after a defined amount of time.
Using the example above, the first 4 secs of the file will be saved as a transcript.
with har as source:
audio = r.record(source, duration=4)
r.recognize_google(audio)
In the files stream, utilize the record() function within a block. As a result, the 4 secs of audio you recorded for 4 seconds will be returned when you record for 4 seconds again.
with har as source:
audio1 = r.record(source, duration=4)
audio2 = r.record(source, duration=4)
r.recognize_google(audio1)
r.recognize_google(audio2)
As you can see, the 3rd phrase is contained within audio2. When a timeframe is specified, the recorder can cease in the middle of a word. This can harm the transcript. In the meantime, here's what I have to say about this.
The offset keywords arguments can be passed to the record() function combined with a recording period. Before recording, this setting specifies how many frames of a file to disregard.
with har as source:
audio = r.record(source, offset=4, duration=3)
r.recognize_google(audio)
Using the duration and the offset word parameters can help you segment an audio track if you understand the language structure beforehand. They can, however, be misused if used hurriedly. Using the following command in your interpreter should get the desired result.
with har as source:
audio = r.record(source, offset=4.7, duration=2.8)
r.recognize_google(audio)
The application programming interface only received "akes heat," which matches "Mesquite," because "it t" half of the sentence was missed.
You also recorded "a co," the first word of the 3rd phrase after the recording. The application programming interface matched this to "Aiko."
Another possible explanation for the inaccuracy of your transcriptions is human error. Noise! Since the audio is relatively clean, the instances mentioned above all worked. Noise-free audio cannot be expected in the actual world except if the soundtracks can be processed in advance.
Noise is an unavoidable part of everyday existence. All audiotapes have some noise level, and speech recognition programs can suffer if the noise isn't properly handled.
I listened to the "jackhammer" audio sample to understand how noise can impair speech recognition. Ensure to save it to the root folder of your interpreter session.
The sound of a jackhammer is heard in the background while the words "the stale scent of old beer remains" are spoken.
Try to translate this file and see what unfolds.
jackmer = sr.AudioFile('jackmer.wav')
with jackhammer as source:
audio = r.record(source)
r.recognize_google(audio)
How wrong!
So, how do you go about dealing with this situation? The Recognizer class has an adjust for ambient noise() function you might want to give a shot.
with jackmer as source:
r.adjust_for_ambient_noise(source)
audio = r.record(source)
r.recognize_google(audio)
You're getting closer, but it's still not quite there yet. In addition, the statement's first word is missing: "the." How come?
Recognizer calibration is done by reading the first seconds of the audio stream and adjusting for noise level. As a result, the stream has already been consumed when you run record() to record the data.
Adjusting ambient noise() takes the duration word parameter to change the time frame for analysis. The default value for this parameter is 1, but you can change it to whatever you choose. Reduce this value by half.
with jackmer as a source:
r.adjust_for_ambient_noise(source, duration=0.5)
audio = r.record(source)
r.recognize_google(audio)
Now you've got a whole new set of problems to deal with after getting "the" at the start of the sentence. There are times when the noise can't be removed from the signal because it simply has a lot of noise to cope with. That's the case in this particular file.
These problems may necessitate some sound pre-processing if you encounter them regularly. Audio editing programs, which can add filters to the audio, can be used to accomplish this. For the time being, know that background noise can cause issues and needs to be handled to improve voice recognition accuracy.
Application programming interface responses might be useful whenever working with noisy files. There are various ways to parse the JSON text returned by most application programming interfaces. For the recognize google() function to produce the most accurate transcription, you must explicitly request it.
Using the recognize google() function and the show all boolean argument will do this.
r.recognize_google(audio, show_all=True)
A transcript list can be found in the dictionary returned by recognizing google(), with the entry 'alternative .'This response format varies in different application programming interfaces, but it's primarily useful for debugging purposes when you get it.
As you've seen, the Speech Recognition software has a lot to offer. Aside from gaining expertise with the offsets and duration arguments, you also learned about the harmful effects noise has on transcription accuracy.
The fun is about to begin. Make your project dynamic by using a mic instead of transcribing audio clips that don't require any input from the user.
For Speech Recognizer to work, you must obtain the PyAudio library.
Use the command below to install pyaudio in raspberry pi:
sudo apt-get install python-pyaudio python3-pyaudio
Using the console, you can verify that PyAudio is working properly.
python -m speech_recognition
Ensure your mic is turned on and unmuted. This is what you'll see if everything went according to plan:
Let SpeechRecognition translate your voice by talking into your mic and discovering its accuracy.
The recognizer class should be created in a separate interpreter window.
import speech_recognition as sr
r = sr.Recognizer()
After utilizing an audio recording, you'll use the system mic as your input. Instantiation your Microphone interface to get at this information!
mic = sr.Microphone()
For raspberry pi, you must provide a device's index to use a certain mic. For a list of microphones, simply call our Mic class function.
Sr.Microphone.list_microphone_names()
Keep in mind that the results may vary from those shown in the examples.
You may find the mic's device index using the list microphone names function. A mic instance might look like this if you wanted to use the "front" mic, which has a value of Three in the output.
mic = sr.Microphone(device_index=3)
A Mic instance is ready, so let's get started recording.
Similar to AudioFile, Mic serves as a context manager for the application. The listen() function of the Recognizer interface can be used in the with section to record audio from the mic. This technique uses an input source as its initial parameter to capture audio until quiet is invoked.
with mic as source:
audio = r.listen(source)
Try saying "hi" into your mic once you've completed the block. Please be patient as the interpreter prompts reappear. Once you hear the ">>>" prompt again, you should be able to hear the voice.
r.recognize_google(audio)
If the message never appears again, your mic is probably taking up the excessive background noise. Ctrl then C key can halt the execution and restore your prompts.
Recognizer class's adjustment of ambient noise() method must be used to deal with the noise level, much like you did while attempting to decipher the noisy audio track. It's wise to do this whenever you're listening for mic input because it's less unpredictable than audio file sources.
with mic as source:
r.adjust_for_ambient_noise(source)
audio = r.listen(source)
Allow for adjustment of ambient noise() to finish before speaking "hello" into the mic after executing the code mentioned above. Be patient as the interpreter's prompts reappear before ascertaining the speech.
Keep in mind that the audio input is analyzed for a second by adjusting ambient noise(). Using the duration parameter, you can shorten it if necessary.
According to the website, not under 0.5 secs is recommended by the Speech Recognition specification. There are times when greater durations are more effective. The lower the ambient noise, the lower the value you need. Sadly, this knowledge is often left out of the development process. In my opinion, the default one-second duration is sufficient for most purposes.
Using your interpreter, type in the above code snippet and mutter anything nonsensical into the mic. You may expect a response such as this:
An UnknownValueError exception is thrown if the application programming interface cannot translate speech into text. You must always encapsulate application programming interface requests in try and except statements to address this problem.
Getting the exception thrown may take more effort than you imagine. When it comes to transcribing vocal sounds, the API puts in a lot of time and effort. For me, even the tiniest of noises were translated into words like "how." A cough, claps of the hands, or clicking the tongue would all raise an exception.
To put what you've learned from the SpeechRecognition library into practice, develop a simple game that randomly selects a phrase from a set of words and allows the player three tries to guess it.
Listed below are all of the scripts:
import random
import time
import speech_recognition as sr
def recognize_speech_from_mic(recognizer, microphone):
if not isinstance(recognizer, sr.Recognizer):
raise TypeError("`recognizer` must be `Recognizer` instance")
if not isinstance(microphone, sr.Microphone):
raise TypeError("`microphone` must be `Microphone` instance")
with microphone as source:
recognizer.adjust_for_ambient_noise(source)
audio = recognizer.listen(source)
response = {
"success": True,
"error": None,
"transcription": None
}
try: response["transcription"] = recognizer.recognize_google(audio)
except sr.RequestError:
response["success"] = False
response["error"] = "API unavailable"
except sr.UnknownValueError:
response["error"] = "Unable to recognize speech"
return response
if __name__ == "__main__":
WORDS = ["apple", "banana", "grape", "orange", "mango", "lemon"]
NUM_GUESSES = 3
PROMPT_LIMIT = 5
recognizer = sr.Recognizer()
microphone = sr.Microphone()
word = random.choice(WORDS)
instructions = (
"I'm thinking of one of these words:\n"
"{words}\n"
"You have {n} tries to guess which one.\n"
).format(words=', '.join(WORDS), n=NUM_GUESSES)
print(instructions)
time.sleep(3)
for i in range(NUM_GUESSES):
for j in range(PROMPT_LIMIT):
print('Guess {}. Speak!'.format(i+1))
guess = recognize_speech_from_mic(recognizer, microphone)
if guess["transcription"]:
break
if not guess["success"]:
break
print("I didn't catch that. What did you say?\n")
if guess["error"]:
print("ERROR: {}".format(guess["error"]))
break
print("You said: {}".format(guess["transcription"]))
guess_is_correct = guess["transcription"].lower() == word.lower()
user_has_more_attempts = i < NUM_GUESSES - 1
if guess_is_correct:
print("Correct! You win!".format(word))
break
elif user_has_more_attempts:
print("Incorrect. Try again.\n")
else:
print("Sorry, you lose!\nI was thinking of '{}'.".format(word))
break
Let's analyze this a little bit further.
There are three keys to this function: Recognizer and Mic. It takes these two as inputs and outputs a dictionary. The "success" value indicates the success or failure of the application programming interface request. It is possible that the 2nd key, "error," is a notification showing that the application programming interface is inaccessible or that a user's speech was incomprehensible. As a final touch, the audio input "transcription" key includes a translation of all of the captured audio.
A TypeError is raised if the recognition system or mic parameters are invalid:
Using the listen() function, the mic's sound is recorded.
For every call to recognize speech from the mic(), the recognizer is re-calibrated using the adjust for ambient noise() technique.
After that, whether there is any voice in the audio, recognize function is invoked to translate it. RequestError and UnknownValueError are caught by the try and except block and dealt with accordingly. Recognition of voice from a microphone returns a dictionary containing the success, error, and translated voice of the application programming interface request and the dictionary keys.
In an interpreter window, execute the following code to see if the function works as expected:
import speech_recognition as sr
from guessing_game import recognize_speech_from_mic
r = sr.Recognizer()
m = sr.Microphone()
recognize_speech_from_mic(r, m)
The actual gameplay is quite basic. An initial set of phrases, a maximum of guesses permitted, and a time restriction are established:
Once this is done, a random phrase is selected from the list of WORDS and input into the Recognizer and Mic instances.
After displaying some directions, the condition statement is utilized to handle each user's attempts at guessing the selected word. This is the first operation that happens inside of the first loop. Another loop tries to identify the person's guesses at least PROMPT LIMIT instances and stores the dictionary provided to a variable guess.
Otherwise, a translation was performed, and the closed-loop will end with a break in case the guess "transcription" value is unknown. False is set as an application programming interface error when no audio is transcribed; this causes the loop to be broken again with a break. Aside from that, the application programming interface request was successful; nonetheless, the speech was unintelligible. As a precaution, the for loop repeatedly warns the user, giving them a second chance to succeed.
If there are any errors inside the guess dictionary, the inner loop will be terminated again. An error notice will be printed, and a break is used to exit the outer for loop, which will stop the program execution.
Transcriptions are checked for accuracy by comparing the entered text to a word drawn at random. As a result, the lower() function for text objects is employed to ensure a more accurate prediction. In this case, it doesn't matter if the application programming interface returns "Apple" or "apple" as the speech matching the phrase "apple."
If the user's estimate was correct, the game is over, and they have won. The outermost loop restarts when a person guesses incorrectly and a fresh guess is found. Otherwise, the user will be eliminated from the contest.
This is what you'll get when you run the program:
Speech recognition in other languages, on the other hand, is entirely doable and incredibly simple.
The language parameter must be set to the required string to use the recognize() function in a language other than English.
r = sr.Recognizer()
with sr.AudioFile('path/to/audiofile.wav') as source:
audio = r.record(source)
r.recognize_google(audio, language='fr-FR')
There are only a few methods that accept-language keywords:
Do you ever have second thoughts about how you're going to pay for future purchases? Has it occurred to you that, in the future, you may be able to pay for goods and services simply by speaking? There's a good chance that will happen soon! Several companies are already developing voice commands for money transfers.
This system allows you to speak a one-time passcode rather than entering a passcode before buying the product. When it comes to online security, think of captchas and other one-time passwords that are read aloud. This is a considerably better option than reusing a password every time. Soon, voice-activated mobile banking will be widely used.
When driving, you may use such Intelligent systems to get navigation, perform a Google search, start a playlist of songs, or even turn on the lights in your home without touching your gadget. These digital assistants are programmed to respond to every voice activation, regardless of the user.
There are new technologies that enable Ai applications to recognize individual users. This tech, for instance, allows it to respond to the voice of a certain person exclusively. Using an iPhone as an example, it's been around for a few years now. If you want Siri to only respond to your commands and queries when you speak to it, you can do so on your iPhone. Unauthorized access to your gadgets, information, and property is far less possible when your voice can only activate your Artificial intelligent assistant. Anyone who is not permitted to use the assistant will not be able to activate it. Other uses for this technology are almost probably on the horizon.
In a distant place, imagine attempting to check into an unfamiliar hotel. Since neither you nor the front desk employee is fluent in the other country's language, no one is available to act as a translator. You can use the translator device to talk into the microphone and have your speech processed and translated verbally or graphically to communicate with another person.
Additionally, this tech can benefit multinational enterprises, educational institutions, or other institutions. You can have a more productive conversation with anyone who doesn't speak your language, which helps break down the linguistic barrier.
There are many ways to use the SpeechRecognition program, including installing it and utilizing its Recognizer interface, which may be used to recognize audio from both files and the mic. You learned how to use the record offset and the duration keywords to extract segments from an audio recording.
The recognizer's tolerance to noise level can be adjusted using the adjust for the ambient noise function, which you've seen in action. Recognizer instances can throw RequestErrors and UnknownValueErrors, and you've learned how to manage them with try and except block.
More can be learned about speech recognition than what you've just read. We will implement the RTC module integration in our upcoming tutorial to enable real-time control.
