The main idea of this inspiration is to process analog voice signal. The theme is implemented for the parallelized persons by voice activated wheelchair throughspeech processing using Digital Signal Processor (DSP). TheTexas Instruments TMS320C6711 DSP Starter Kit (DSK) isconnected with the wheelchair for processing of the voicesignal. The DSK calculates the energy, zero crossing andstandard deviation of the spoken word. It also generatesdifferent 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.
Digital Signal Processing, speech processing, voice recognition, voice controlled wheelchair.
