Speech is one of an essential medium by which communication can take place. With the invention and widespread use of mobiles, telephones, data storage devices etc. has provided a significant help in setting up of speech communication and its analysing. The term and the basic concept of speech identification began in the early 1960`s with an exploration of voiceprint analysis which was somewhat similar to fingerprint concept. It was in 1984 that a science fiction called “Star Trek to George Orwell`s,” derived the idea that a machine can recognize the human voice. [1] Nowadays, with further growth & advancement in the field of speech recognition, the humans who are physically challenged such as blind and deaf can easily communicate with the machines. So in biological terms, a voice that is being generated through trachea will be decoded by the brain.
