S. Siva Srujana | S. Jahnavi | K. Jhansi

Abstract: In our day to day life most of the task we carry out involves speaking and hearing. The deaf and dumb people have difficulty in communicating with others who cannot understand sign language and misinterpreters. In this paper, we designed a simple embedded system based device for solving this problem. we have use flex sensor for getting the data from the deaf and dumb people using sign language and microcontroller AT89c51 for controlling all operations and APR 9600 voice chip for voice storage. LCD display and speaker are used as output device to convey the message to deaf and dumb people. Keil and proteus software tools are used for compiling software coding and simulating the design.
