Voice Commands Execution with Speech Recognition and Synthesizer

Voice technology is one of the fastest growing modern engineering technology with a wide scope for application in various disciplines of life. Nearly 20% of the world’s population are suffering from various disabilities, out of which many of them are blind or unable to use their hands effectively. Speech has the potential to be a better interface other than keyboard and pointing devices. The Speech recognition and synthesizer systems will provide a significant help to them in operating the computer through voice. The code excited linear prediction (CELP) is used for speech coding. The proposed project is able to recognize the voice of a person and convert the input voice into text. It also enables the user to perform operations such as “opening and closing of various applications and windows, selecting the necessary as well as the entire text, media controls, reading documents, system termination, social interaction� etc., by providing the voice of the user as input. It has a high energy saving efficiency.
