Voice Operated Wheel Chair For Physically Challenged

The objective of this paper is to facilitate the movement of people who are disabled or handicapped and elderly people who are not able to move well. The result of this design will allow certain people to live a life with less dependence on others. Speech recognition technology is a key which may provide new way of human interaction with machines or tools. Thus the problem that they faced can be solved by using speech recognition technology to move the wheel chair. This can be realized with the Bluetooth as an intermediary. An interface is designed therefore to develop the program for recognizes s voice in turns control the movement of wheelchairs. The Arduino controls the wheelchair directions. Ultrasonic sensors are used to detect obstacles. The prototype is designed in such a way that it can be used independently and efficiently with less effort. It saves time, reduces cost and energy of the users.
