Voice recognition
Alternatively referred to as speech recognition, voice recognition is an ability of a computer, computer software program, or hardware device to decode the human voice into digitized speech that can be interpreted by the computer or hardware device. Voice recognition is commonly used to operate a device, perform commands, or write without having to operate a keyboard, mouse, or press any buttons. Today, this is done on a computer with automatic speech recognition (ASR) software programs. Many ASR programs require the user to "train" the ASR program to recognize their voice, so that it can more accurately convert the speech to text. For example, a user could say "open Internet" and the computer would open an Internet browser and allow that user to browse the Internet.
The first ASR device was used in 1952 to recognize single digits spoken by a user (it was not computer driven). Today, ASR programs are used in many industries, including Healthcare, Military (i.e. F-16 fighter jets and helicopters), Telecommunications and Personal computing (i.e. hands free computing).
Although
speech recognition can be done using any traditional
microphone, you'll get much better results if
you use a headset.
