Voice Controlled Smart Wheelchair

This project describes the significant design to build a voice-controlled wheelchair. The project is intended to increase the ease of mobility for disabled/injured people. The design would allow these people to live more independently. Presently, people use blow- tubes or chin-joysticks to control motorized wheelchairs. Speech recognition is a prominent technology which can give an alternative to people to interact with machines or devices especially to those who are quadriplegics. The rate of physically challenged and old aged people is increasing day by day. They are not able to move and has to dependent upon others for their movement. The project aims at controlling a wheelchair by means of human voice. The voice recognition is done by android phone and is connected to the wheelchair system using Bluetooth technology. The design and implementation of a voice controlled wheelchair motion based on an efficient and unique algorithm for accurately detecting voice commands. The proposed voice controlled wheelchair can be very effective for persons with disabilities where they can dynamically give the wheelchair voiced instructions instead of being stagnant in a place for its controlling. Apart from its possible application in industrial automation, voice controlled robotic motion can also encourage the view of a wheelchair as a partner rather than a tool by providing a smooth, easy and flexible mean of self-reliant movement for the physically challenged people.
