Speech enabled operating system control

Our goal is to provide the computer with a natural interface, including the ability to understand human speech. For this purpose, we propose a way how to operate an operating system with voice command. At first, the user initiates a given command by his voice through the microphone then the recognition software of the proposed system will take over to recognize the command. If the recognition is succeeded or matched with one of the given voice command then it will perform the operation on the operating system according to speaker´s speech command. In our proposed system we have used Markov chain model for voice recognition process and voice-XML for creating the voice grammar in the software part. It has the flexibility to work with the speech of any user means and remove the problem of dasiahesitationpsila which is very effective for spontaneous speech recognition. The proposed system minimizes the error rate up to 30% which is very precise for any speech recognition system.
