Hand Gesture-Based Vocalizer for the Speech Impaired

Abstract

Communication is a basic form of interaction between two individuals. Humans have been using speech to communicate with each other since the ancient times. But for the speech- and hearing-impaired people, it becomes a real challenge to put up their views due to their disability. This project aims at developing a microcontroller-based vocalizer that converts hand gestures to audible sound. The system is easy to calibrate according to the user’s need, thus removing the complications of different hand sign conventions used around the globe. This system is further developed to work as a home automation system that uses hand gestures to control various appliances like fan or light.
