A speech controlled artificial limb based on DSP chip

A speech signal pattern recognition DSP-based system is constructed for real-time control of artificial limb through precise identification of speech and speech command. The portable DSP-based system provides a more effective method to provide multiple control commands than the electromyographic signals from the amputation stump or residual limb. The traditional prosthetic arm can not achieve many complex actions because the EMG of the residual limb is hard to detach from the many different control signals. Goals of multiple command recognition and low cost were achieved by using a portable DSP-based system.
