A Novel Approach of sign recognition for Indian sign language is proposed in this work to dual way communication system for deaf -dumb & normal people. . Sign language is only essential communicating tool for deaf & dumb people. It is a subset of gestures or signs made with fingers, hands, head and face etc. Each gesture in SL has a specific meaning & that is assigned to it. Deaf –dumb & normal people directly not communicate with each other. Every country has developed its own SL. In India, this sign language is called as "Indian Sign Language (ISL)". In this approach first gesture is converted into text and then voice format, So normal people understand the meaning of that gesture. Second, Voice is converted into text and then gesture, so physically impaired people can understand it .In this vision based approach used with the dynamic gesture. Pre-processing, Segmentation, Feature extraction, Classification these four are the main steps to recognize hand gesture. In this approach key frame extraction with histogram analysis is used for extract the main frame which has a sign & removes the unwanted frame.
