Paper Title
Voice Operated Wheelchair For Physically Challenged People

Abstract
A system of wheelchair is designed which is operated using voice Commands and is useful for the person who is physically challenged. This paper explains the speech recognition to provide the hi tech approach towards the goal that is to operate wheelchair with less efforts. By using speech recognition technique for controlling the wheelchair, we have to speak into the microphone and the Raspberry pi B follows the commands and perform the operations on the Dc motor. This paper presents the concept of speech recognition implemented with the use of Hidden Morkov Model in an offline mode (without internet) while the available models come in online mode with the use of internet. In this way, a navigation framework for wheelchairs in which integrates various alternative input interfaces where voice control is done with CMU Sphinx. This enables patient with limited control over their limbs to navigate using voice commands. Keywords— Speech recognition, Raspberry Pi B board, Sphinx.
