Approach Towards Voice Controlled Wheelchair System for Physically Challenged Person

Abstract

Voice controlled wheelchair system is aimed to control a wheel chair by using speech recognition module. The system is designed to control a wheelchair using the voice of any person. It is used to facilitate the movement of people who are disabled or handicapped and elderly people who are not able to move well. The goal of this system will allow certain people to live a life with less dependence on others for their movement as a daily need. Speech recognition technology is a key technology which will provide a new way of human interaction with machine or tools. Therefore, the problems that they face can be solved by using speech recognition technology for the movement of wheelchair and controlling the home appliances. This can be realised and optimised with use of the smart phone device (google voice service) as an intermediary or interface. This paper uses Arduino kit microcontroller circuit and DC motors to create the movement of wheelchair and Ultrasonic Sensors to detect the hurdles in between wheelchair and the way of direction.
