Hand Gesture Recognition and Voice Conversion System for Dumb People

In our country there are 2.78% people are speech disable[dumb]. Speech is a necessary element for every human being people suffering from speech disability are apprehensive while communicate with normal people. This project proposes development of vocalize to communicate speech disable person to normal person. Technologies that employ recognition of gesture are broadly classified into two types: vision based and sensor based, the drawbacks of vision based solution level is the level of complexity of algorithm implemented in capturing a movement. MEMS (Micro-Electro mechanical system) Sensor is a sensing Technologies consisting of electronic parts of size of order of microns which are capable of movement of with or without external force .MEMS sensor can easily place on human body parts like hands .bending of fingers possess significant role in performing gestures by hands flex sensor is used in this project as an example of bend sensor. Three-dimensional accelerometer sensor has been created for measuring involuntary human hand motion[2].
