This paper is to process analog voice signal. The theme is implemented for controlling the wheelchair by voice through speech processing using Hawk board (OMAP processor). The adopted model is based on grouping a ARM and a DSP processor for speech enhancement with a voice recognition module for isolated word and speaker dependent. The Texas Instruments OMAP-L138 is integrated in order to enhance the quality of speech signal by reducing noise and connected with the wheelchair for processing of the voice signal. The Hawk board denoises speech signal and HMC2007 recognizes the commands.
