Abstract: Sign language is a language which is used for communication between the hearing/speech impaired people along with others who understands it. Sign language relies on sign patterns, i.e., body language, orientation and movements of the arm to facilitate understanding between people. This paper is aimed at reducing the communication gap between the normal people and hearing/speech impaired people by converting sign language into English speech or text. The system will convert the data into speech/text. The whole system will be implemented on a MATLAB and Simulink.
