Speech technology is one of the fastest growing modern engineering technology with a wide scope for application in various arenas and disciplines of life. It has many potential benefits and is useful to people in many walks of life. Nearly 20% of people of the world are suffering from various disabilities; many of them are blind or unable to use their hands effectively. The speech recognition systems inthose particular cases provide a significant help to them, so that they can share information with people by operating computer through voice input.This project is designed and developed keeping that factor into mind, and a little effort is made to achieve this aim. Our project is capable to recognize the speech and convert the input audio into text; it also enables a user to perform operations such as “open and close applications and windows, select text, media controls, read text, system termination, social interaction”etc.,by providing voice input. It also helps the user to open differentsystem software such as opening MS-paint, notepad and calculator. At the initial level effort is made to provide help for basic operations as discussedabove, but the software can further be updated and enhanced in order to cover more operations.
