Design and Development of Voice Controllable Wheelchair

In this work a voice controlled wheelchair is made for physically challenged peoples or patients whose hind limbs are not in working condition. Hence, he or she can control the wheelchair by own voice commands or of the family members. To accomplish the task Arduino microcontroller board is used which receives the voice commands either from Bluetooth module via smartphone or from voice recognition module from microphone attached to it. Further matching it with preloaded voice commands and develop movement accordingly. In the subsequent sections of the paper give more concentration on further objectives to achieve reduction in motor speed smooth movement of vehicle by two motors and the wheels as per the command. The main objective of current work is to make it as simple as possible. Certain theoretical results are also obtained by formulation and design calculation.
