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.

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. 1970s

Ugh . 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.
