Abstract:
In this project, a wheelchair controlled by voice commands has been
constructed to help people who can’t walk or moving freely. The system which
will be built will control the wheelchair's movement in four directions, front,
behind, right and left, based on voice commands. It will use MFCC technique to
extract features of each voice command. This system generally consists of many
subsystems, such as a microphone which will receive voice commands and convert
it to electrical signal to pass it to DSP kit for signal processing, after that a
microprocessor become as interface to control wheelchair’s movement and
direction. To prevent accidents with obstacles, sensors were added to a wheelchair
to find the range from any obstacles and avoided.
