A Novel Communication System For Deaf And Dumb People using gesture

Abstract

Human Beings know each other and contact with themselves through thoughts and ideas.The best way to present our idea is through speech. Some people don’t have the power of speech; the only way they communicate with others is through sign language. Now a days technology has reduced the gap through systems which can be used to change the sign language used by these people to speech. Sign language recognition (SLR) and gesture-based control are two major applications used for hand gesture recognition technologies. On the other side the controller converts the sign language in to the text and speech which gets converted with the help of text to speech conversion and analog to digital conversion. A Dumb person throughout the world uses sign language for the communication.The best way to present our idea is through speech.
