Helping Hand Device for Speech Impaired People

Abstract

In this paper, we propose a well-organized system to bridge the gap of communication for the speech-impaired person and assist him in a smooth conversation with a normal person by providing an artificial mouth. This paper includes the method of easy conversion of the hand gestures and the intact conversion of these gestures into speech and text messages. A flex sensor is used to take the input from gestures and forward it to the microcontroller Arduino Uno where a template database is created to assign the desired message which is further processed to be displayed on the LCD display and the acquainted sound signal stored in the Secure Digital card is amplified before it is provided to the speaker to generate the audio signal and ensure better sound quality.
