Voice recognition technology is a very recent development in this field. For getting the output on the computer screen, one had to type on the keyboard. With voice recognition, one can simply talk to a computer. In other words, as you speak, you can see your spoken words on the computer screen. This greatly increases the speed on your working on the computer. People with a variety of physical constraints or even disabilities can use this technology in a very efficient manner.
Voice recognition plays a very important role in virtual reality too. As the user speaks to his computer, he is free to control the simulation in whatever manner he wants as his hands are totally free. Fans of virtual reality find this to be a real boon for them. For more info visit, AudioRecog.com
