  This software project based paper is for a vision of the near future in which
computer interaction is characterized by natural face-to-face conversations
with lifelike characters that speak, emote, and gesture. The first step is
speech. The dream of a true virtual reality, a complete human-computer
interaction system will not come true unless we try to give some perception to
machine and make it perceive the outside world as humans communicate with each
other. This software project is under development for listening and replying
machine (Computer) through speech. The Speech interface is developed to convert
speech input into some parametric form (Speech-to-Text) for further processing
and the results, text output to speech synthesis (Text-to-Speech)
