Design of Voice Based Smart Wheelchair System

Abstract

The main purpose of this project is to design a motorized, voice controlled wheelchairby using speech recognition module The objective of this project 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. The design supports voice activation system for physically disabled persons. Arduino microcontroller and speaker dependent voice recognition processor have been used to support the navigation of the wheel chair. GPS and GSM modules have been used for surveillance purposes. The direction and velocity of the chair are controlled by pre-defined voice commands.The wheelchair does not respond to a false speech command.It proved a good working in clear and noisy environments with safe movement. The results of this project show that this project can be used for future research works and to design excellence innovation that meets market need and public interest.
