The aim of this project is to develop a voice operated wheelchair which is ergonomic enough to be operated and understood by people of all age groups without the need of any additional help. Also, the end product must not be held back by any linguistic barrier and must enable universal usability. Thus, the need for a robust and comprehensive voice recognition and processing system looking beyond the traditional approaches arises. To meet the above objectives, the de-sign of the wheelchair is such that it incorporates minimum possible user interface, self-reliant circuits to accurately recognize voice and generate proper response in a time period as little as possible using hardware which can be easily procured, repaired and maintained. The wheelchair uses an onboard power supply which lasts all day for domestic use and can be charged while the wheelchair is not in use. Thus hardware and software design and implementation regarding this project was carried out keeping in mind the above goals and the project was completed within the anticipated time frame.
