SPEAKING MICROCONTROLLER FOR DEAF AND DUMB

Abstract

Microcontroller based speaking system for deaf and dumb is designed to give the signs,
which are preloaded in the device. It is a microcontroller based device, which gives the alert
sounds just by pressing the control buttons, which are given some redefined messages like
asking for water, washroom etc., here the person can just press the control button which
indicates the sign of water (example) then the device sounds the same with some output
volume. Microcontroller is the heart of the device. It stores the data of the needs of the
person. So that it can make use of the data stored whenever the person uses the device. This
device helps the deaf and dumb people to announce their requirements. By this the person
who is near can understand their need and help them. This saves the time to understand each
other and ease in communication.
