Voice Controlled Wheelchair Using DSK TMS320C6711

The main idea of this inspiration is to process analog voice signal. The theme is implemented for the parallelized persons by voice activated wheelchair through speech processing using digital signal processor (DSP). The Texas Instruments TMS320C6711 DSP starter kit (DSK) is connected with the wheelchair for processing of the voice signal. The DSK calculates the energy, zero crossing and standard deviation of the spoken word. It also generates different desired analog signals according to the spoken words which further amplified and converted into digital. These digital signals are used to operate the stepper motor. Five words are recognized which are forward, reverse, left, right and stop. The results at the end show the efficiency of the system.
