ABSTRACT

This research describes Intelligent Voice Controlled Wheelchair which operates on
user’s voice commands. The disabled people cannot move from one place to another on
their own. They continuously need someone to help them in getting the wheelchair
moving. This voice controlled system make them more independent. Powered
wheelchairs with the standard joystick interface are unable to be controlled by many
people. A voice controlled wheelchair can provide easy access for a physical disabled
person who cannot control their movements especially hands. Few patients such as
quadriplegic, cerebral palsy and multiple sclerosis are dependent on other people to
move from one place to another and due to this they don’t have the freedom of
mobility. This voice controlled wheelchair help them to drive the wheelchair without
anyone’s help. This system can be controlled by the simple voice commands given by
the user. Depending upon the direction specified in the commands, the Arduino will
drive the motors. The speech recognition is done by voice recognition module,
connected with Arduino. The wheelchair would operate on real analogous voice signal of
patient or user using the wheelchair.
Keywords: Voice control, quadriplegic, cerebral palsy, multiple sclerosis and arduino.
