The day is not far away, where, computer’s peripherals performing tasks by taking commands from the most natural form of communication: THE HUMAN VOICE. Yes, this idea of developing a voice operable hardware device by using the speech recognition technology is to develop a basic application which demonstrates a hardware chip responding to the commands given by voice along with a GUI. Several years of research has already been done on the speech recognition technology and in our exploration we found that all the speech-recognizing engines were based on the HMM concepts although they may be written in different programming languages. HMM is the “Hidden Markov Model”. This concept aims at building and manipulating Hidden Markov Model (HMM). HMM is primarily used for speech recognition applications. After exploring the options available for selecting a speech engine, which recognizes words, the best results were observed in a program written in Java. To show the hardware operation we have made use of the 8051 micro controller and embedded “C” code for its operation. So by using this as foundation we can build many applications like for ex: operating a printer through voice and any other output device connected to the computer. The advantage of our work in this paper is that our application is speaker-independent that can recognize continuous human speech regardless of the speaker and that can continually improve their vocabulary size and recognition accuracy.
