A dumb person always uses gestures to convey his ideas to others. But it is always difficult for a normal person to understand this sign language. This article presents a solution that automatically recognizes hand gestures and converts them into text and language so that people with intellectual disabilities can easily communicate with normal people. The images of the hand gestures are acquired using the built-in LAPTOP camera or the webcam through a color detection technique. The gestures of the hand are detected to realize the different gesture of the hand. The system uses image processing technology for capturing and converting gestures. The hand gesture detections are performed in the operating system and provide speech output via a speaker. Based on recognized hand gestures, the recorded sound will be played. In the proposed work, the captured images are processed via MATLAB on PC and converted to screen text and speech by loudspeaker.
