Designing of an Embedded Communication Aid for Speech Impaired People

In our country around 2.78% of people are not able to speak (dumb). Their communications with others are only using the motion of their hands and expressions. We proposed a new technique called artificial speaking system for dumb people. It will be very helpful to them for conveying their thoughts to others. Some people are easily able to get the information from their motions. The remaining is not able to understand their way of conveying the message. In order to overcome the complexity this system is introduced for the deaf and dumb people. This system is based on the motion sensor (Flex sensor). According to speech impaired people, for every motion they have a meaning. That message is kept in a database. Likewise all templates are kept in the database. In the real time the template database is fed into raspberry pi and the motion sensor is fixed in their hand with the help of glove. For every action the motion sensors get accelerated and give the signal to the raspberry pi processor. The processor matches the motion with the database and produces the speech signal. The output of the system is using the speaker. By properly updating the database the dumb will speak like a normal person using this system. The system can also convert the output into text.
