Project Title

Design and Development of sign to speech and text system for dumb people using smart glove

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

Smart Gloves is equipped with microcontroller. The smart, technologically advanced glove have advanced circuit design for conversion of sign to text and speech.This glove help to remove communication barrier between normal and dumb people.Sensors are used for the detection of sign and then further processed by pic microcontroller. The text output is displayed on lcd .For voice section bluetooth module is used which is pair with android.Android  is used for speech output

Project Objectives

The main objective of this project is to help  dumb people by removing communication barrier.
To convert American sign language into voice.
To convert American sign language into text.

Project Implementation Method

Implementation of complete hardware consists of complete implementation of the sign to speech/text conversion system. We used Flex sensors which detect the sign language of the mute people, voltage booster circuit in order to provide the external clock to the pic16f887a because this microcontroller do not have an internal clock. LCD is interfaced with the pic microcontroller.Pic is the main component of the whole system and thus we can say that it is the brain of the system sign to speech/text conversion. LCD is used to display the text output. Moreover Audio Module also interfaced with Pic and hence use for the speech output of the system. All parts are combined on single Vero board and the connected with each other by the process of soldering.

Benefits of the Project

Removes communication barrier between speech impaired peoples and normal peoples
Compact system
Flexible to user
Takes less power to operate
Low cost
