Design and Development of an Assistive Device for Speech Impaired using Power Electronics Based Concepts with Power Quality Improvements

Abstract

Communication between a deaf-mute and a hearing person has always been difficult. The study outlines a method for deaf-mute people to overcome this communication barrier by constructing an assistive gadget. A sign language translator, speech recognition unit, traffic sensor module, and GSM-GPS unit make up the system. The sign language translator module converts gesture signs to text before converting them to voice. A voice recognition system is used to transform acoustic speech to written form. As a result, two-way communication is feasible. To lend a helping hand in times of peril or a critical circumstance GSM and GPS technology are utilized to send the gestures, as well as position and time information, to the deaf-mute person's guardian. A deaf individual receives traffic alerts by the use of a sound sensor, an obstacle sensor, and a vibrator. The primary benefit of this project is that it may be utilized as an assistive device for deaf-mute people for both communication and safety.
