Implementation of gesture based voice and language translator for dumb people

Dumb persons communicate through gestures which are not understood by the majority of people. Gesture is a movement of part of the body, especially a hand or the head, to express an idea or meaning. This paper proposes a system that converts gestures given by the user in the form of English alphabets into corresponding voice and translates this English voice output into any other Microsoft supported languages. The system consists of MPU6050 for sensing gesture movement, Raspberry pi for processing, three button Keypad and speaker. It is implemented by using trajectory recognition algorithm for recognizing alphabets. Raspberry pi generates voice output for the text in multiple languages using voice RSS and Microsoft translator. When tested, the system recognized A-Z alphabets and generated voice output based on the gestures in multiple languages.
