Do you know what the Voice Recognition System is and how it works . Along with this, today we will tell you what are the advantages and disadvantages of this technology. I will also tell you about its history. Today we will give you all your information, so let us know.
How would you like it if your computer or Smartphone talks like your friend and also answers all your questions. Yes, you heard it right, but some people may be feeling this joke or dream. But this is true. Now technology is progressing so fast that it is also possible. You do not even need a keyboard in this technology . Like you will say hello, then your phone will also answer you immediately. It was impossible to do all this at one time, but gradually when the Computer Scientist and Mathematician started working on this concept one day and night, there was a technology invention called Voice Recognition. Nowadays this technology is available in every mobile phone and computer.
What is the Voice Recognition System: Voice Recognition is also called Speech Recognition . It is a computer software program, it is also a hardware device that has the capability to understand Human Voice. Speech Recognition is a technology that takes words spoken by Human like Input and converts those words into digital form, taking action over it.
This technology is used to operate mobile phones, to give commands to mobile and to search through voice. In this, you do not need to use any keyboard, mouse and neither do you need to press any button. For this, a program is used called ASR (Automatic Speech Recognition). For this, you need to train (teach) ASR PROGRAM. By which it will answer your questions by recognizing your voice and if you are given the command to do any work, then it will show working. Take an example, you will say "Open WhatsApp", then the mobile opens the WhatsApp by understanding the command given to you.
The best example of this technology is " Google Assistant " which is Google's application. SIRI is also an example of voice recognition technology software. This is Apple's application. You will find many software in the market which is run by Speech Recognition . The most used of this Voice Recognition Technology is in Bio matrices, Office , Medical. So let's now know how it works .. How Voice Recognition Technology Works
It is very important to know how it works. When you say something, on-screen-text (what you say will appear on mobile screen) or to convert it into a command, Voice Recogntion has to go through a lot of complex steps. Whenever you say something, a vibration is born. This Vibration is nothing else but this Analog Signal. ADC Translator is used to convert Mobile or Computer Analog waves into Digital. You must know this, understands Computer Digital Signal only.
ADC follows all these steps to convert Analog to Digital. Divide the Sounds into smaller Samples in a Particular Interval. Digitizes that sound. System Digitize Sounds Wave removes Unwanted Noise by filtering. Also normalize the sound and move the volume to the Constant Level. There is a need to Constant the level of Sound because not everyone pronounce in the same Speed. However, the Input Sound is easily matched with Sound already available in Sound System Memory.
After this, these Sounds are divided into small amounts and small isa means 1 second's fifth part or thousandth part. With which some of these letters can be easily identified such as P, B, T because it is easy for us to understand them, but if it is a very difficult task in the field of Computer and Smartphone. That is why it is devide in such small matters.
Now the last step is left, small notes of these sounds are matched with digital signal stored in the system. Just like the one that matches with the 'G' signal is G, O with O, D. With D. If these three are mixed then "God" will be created. If you talk about Google Assistant, then by speaking the word God, it shows the meaning of God. So now let's talk about the example of Voice Recognition Software. . Example of Voice Recognition Software
In this, we will talk about 1 special application which runs from the application " Voice Recognition Technology ".
Google Assistant
This is a people's favorite application. This Assistant has been developed by Google. It was announced at the Google I / O conference in May 2016. In this, you can do 2 way conversion, meaning you can talk with your friend the same way you can talk. And you can also operate your mobile without touching it.
Now a question may have come in your mind that what can this application do. So below are some Commands that you can use in Google Assistant. You will also get an answer immediately. Remember, first pressing the Home button in Mobile, use all the commands given below. Or use OK to speak Google.

Show me my Emails : The emails that came in Gmail. Show them When you use all these Commands in your mobile, then you will understand how Voice Recognition works.
This is how Apple's Siri application works. Let us now know what the application is.
Applications of Speech RecognitionIt is gaining a lot of popularity in the fields of technology, let's know where else its application is. There is a lot of contribution to device control. Like by speaking Ok Google, you can control your mobile completely through Voice and you can give any command.
In this way, you can control your mobile through Bluetooth by connecting Call Receive, Music and Map with Voice Command. You do not need to touch mobile at all.
Voice Typing- You will know about Google Voice Typing, in which you can write anything by speaking. You can write a lot in a very short time. Voice Typing is also very speed and you can write without spelling Mistake.

You must have heard the name of bio metrics- where this technology is used more on it. Voice is used for id verification in big software company. Time is ahead to know the history of this technology. So let's know.
History Of Voice Recognition Technology
1. 1950s to 1960s:
This was the period when Voice Recognition Technology was a small child which meant the time of harvest. At that time Voice Recognition worked only on Number and Digit. In 1952, a scientist named Audrey invented it at Bells Laboratory. But even this, only the number could understand.
2. 1960s to 1970s:
After this, in 1962, a company named Shoebox was developed again, this time the thing was something else, because of this number, now this technology was now beginning to understand English words as well. After some time, along with time, the ability to understand 9 consonant and Vowel also came.
3. 1970sUgh .
The S Defense department changed its thinking and increased its contribution to Speech Recognition Technology, from 1971 to 1976, he started a research program called DARPA SUR (Speech Understanding Research). The result of this program was quite good Carnegie Mellon developed Harpy. In which there was absence of understanding 1011 words. He created a system that could understand Logical Sentence. Due to the advancement in Bells Laboratory, it was so advanced in the 1970s that it was easy to understand the language of two persons.
4. 1980s:
This was the era of the Markov model, it was somewhat different, in which it used data to determine the unknown sound. In which there was no contribution of Speech Pattern or Fixed Template . This technology contributed well to Business Industries and Business Application.
With the help of this technology, a doll was created for the children in 1987. Whose name was Julie this doll was practiced in such a way that she could answer the remaining things. One problem in Surrey Voice recognition during the 80s was that you had to take a break after speaking something.
5. 1990s
The 1990s was the era of Microprocessor. Speech Recognition Software also started appearing in front of people. There was a company called Dragon. Release a software called 'Dragon Dictate' This was the world's first Voice Recognition Software. Common people could also use this software.
In 1997, while improving it, another software was developed called "Dragon Naturally Speaking" Software. In which there was absence of understanding 100 Sabbaths. BellSouth introduced Voice Activated Portal (VAL) and it had many mistakes.
6. 2000s
Till 2001, Google was on Voice Recognition technique, when Google killed Entry. Google invented the Google Voice Search Application for iPhone. Which, using the Data Center, used to answer the questions of the users by matching the data spoken by human to the data center which is the data.
You must have known that Google is very homogeneous. In 2010 Google released a Personalized Recognition application for Android. Through which Google started recording Voice Quries to create a good Speech Model. Due to this, a database of 230 Billion Words was created. Right now the name of the application is Google Assistant, about which I have already given you information.
This Personal Assistant is quite intelligent, it is also funny because you can also talk jokingly with it through Voice. Apple also, without delay, invents its Personal Assistant, which is named Siri. Hopefully, you must have felt good about history, now know about its advantages and disadvantages.
What are the advantages and disadvantages of Voice Recognition
Just as every technology has its advantages and disadvantages, so too are this Voice Recognition Technology. I know if you are anxious to know this, then start with goodness.
Advantage
1. You can get your work done easily and in less time.
2. You need to touch the mobile to get you very little time or no time. You can do all the tasks by just speaking through Voice.
3. For a person who is physically Akhyam, he can do all his work by becoming very helpful and companion. Neither does he need to hold a mouse nor a keyboard. If you want to write some text, then it is possible through Voice Command.
4. Useful for those who have absolutely no hands.
5. You do not need to care for Grammatical Error and Spelling at all.
6. If we talk about Speed then it is quite fast. You cannot even think about which you will keep on speaking and will keep writing.
7. For students, this is a farce, nor do they need to type anything, just those who ask questions will get answers immediately.
Loss
1. As you have been told, Google records your voice. It may also be that your voice is put in a wrong job. 2. Understanding Voice is a little smiling at the time of onset. 3. Due to incorrect pronunciation, the input of word can also be taken wrong and whose output can also be wrong. 4. When the background is sound then the data starts to write less Accurate and upside down. 5. In a quiet place you will have to speak loudly, which can spread the peace. 6. Even if there is a change in your Tone, it is also a little easy to understand Speech. Contact us :https://lntechinfo.in/contacts/
