DESIGN AND DEVELOPMENT OF AN ASSISTIVE DEVICE FOR SPEECH AND HEARING IMPAIRED

Radha H G, Shruti S D, Kanya B S

Abstract


Communications between deaf-mute and a normal person have always been a challenging task.The paper describes a way to reduce this communication barrier by developing an assistive device  for deaf-mute persons. The system consists of a sign language translator, speech recognition unit, traffic sensing module and GSM-GPS unit. Sign language translator module  translates the gesture signs to text and further it is converted to voice . To convert acoustic speech to text form speech recognition system is used. Hence two way communication is possible.To  provide assistance at times of danger and critical situation GSM and GPS technologies are used that transmit the gestures to the respective guardian of deaf-mute person along with location and time information. Traffic alert is provided to deaf person using sound sensor, obstacle sensor and vibrator. The main advantage of this project is, it can be used as an assistive device for deaf-mute person for both communication purpose and safety purpose.
