Voice signals are the most important means of communication among human. Every conversation and interaction is done employing voice signals. Voice signals can be converted into electrical signals using a microphone. This electronic document represents a project which aims to design and construct a wheelchair that can be controlled by human voice. This is for paralyzed people that are severely injured and can't even use their hands to control the joystick wheelchair. Physical disability can occur due to multiple reasons like injuries from an accident, age-related & health problems. A wheelchair is used to provide a mode of transportation for disabled people with impairments in hands and legs. This project will provide smooth self-drive indoors and outdoors. It can detect objects, stairs, or any constraint and can stop autonomously. The prototype of the wheelchair is constructed using a microcontroller, chosen for versatility and performance in operations and communication with other electronic devices. This project is based on the basic principle of motor controlling system and voice processing using a microcontroller. The system has been designed in a cost-effective way so that it can be commercialized and needy users may benefit from it.
