2.1.28 Voice Recognition

Voice-recognition devices are available that can b e used to provide voice input directly to a computer. The computer recognises the spoken words and converts them to output, either in audio form or in printed form. Since these devices understand a limited vocabulary, they are not widely used at present.

VOICE RECOGNITION AND SYNTHESIS

Computer recognition of human speech and transformation of the recognised words into computer readable digitised text or instructions is known as voice recognition. Computers, at present, have limited capability of recogni sing spoken words.

The process of obtaining the audible output of computer-based text in the form of synthesised speech that people can recognise and understand is known as voice synthesis. Voice synthesis is much easier to achieve than voice recognition. This capability has helped blind people gain increased access to written works.
