Gesture Aided Speech for Deaf and Mute

Speech impaired people make use of sign language to communicate along with normal people. Common people also face difficulties to understand the gesture language. In order to minimize these real time issues, an attempt has been made to develop a system which consists of Flex sensors attached with the Data gloves along all fingers. These will be wearable gloves converts hand gestures into an audio output to interpret the expression. This reduces the communication gap that exists between mute and ordinary people. The proposed system plays corresponding recorded voice on an android phone connected to the hardware system via Bluetooth Module as an interpretation of the gesture. It is achieved by integrating flex sensor and 8051 microcontroller. The phone will use a text to speech converter to produce the output of corresponding gesture. This system offers high reliability and fast response as microcontroller works at a speed of 12 MHz. Processing time of microcontroller is much less than the time taken for a human to change from one gesture to another, the system works efficiently in real time scenario hence making the system faster.
