ABSTRACT

Dumb can be defined as Muteness, the condition of being unwilling or unable to speak. The requirements of a communication aid for the dumb are discussed and a prototype system is described which has been found to fulfill these requirements adequately. Messages are entered into the system using a Switch array, and user defined 8 commands are programmed in the system such that if the dumb person wants to communicate with normal people he/she can press the specified switches in the switch array. The same information will be delivered out as a voice signals by using a text to speech converter module which is again given to a amplifier unit to get the exact information without any noise, and from there to a speaker.

This project describes the design of a simple, low-cost controller based Text-to-Speech conversion system. We can get both the voice announcements as well as a 16X2 LCD display is used to display the text messages on it.

This project uses MCU. This is a best as well as cost effective system for the speechless to communicate with the normal people such that any one can understand their message easily without any difficulty.

This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
