Computer-Aided Interpreter for Hearing and Speech Impaired

The difficulties faced by hearing and speech impaired people in communicating with others and among themselves can be easily overcome by building an assistive communication system. This real time communication system enables differently impaired people to communicate among themselves without an intermediate human translator. The proposed system is a potential human-computer and computer-human interaction for hearing and speech impaired people with normal people. This is achieved using Natural Voice processing and Digital Image Processing algorithms. The algorithm used, takes necessary precautions to combat a noisy environment and is particularly effective for human voice as it represents the speech in the Mel Cepstrum domain (B.P.Bogert, M.J.R.Healy, and J.W.Tukey-1963). A database is used to maintain the back-end of the system and efficient matching algorithms are employed. The system simulation has been done in MATLAB to build this community assistive digital communication system.
