| Prosthetic hand is an attentive research project in the fields of robotics and biomedical engineering, research on this project is of practical significance to improve the living situation and welfare benefits of amputees. This paper describes a speech recognition control system for prosthetic hand based on SPCE061A microcontroller core. A prosthetic hand is controlled by speech recognition and wireless communication. The control system prosthetic hand based on makes up that based on electromyography (EMG) and electroencephalogram (EEG) so that it can meet handicapped's need and promote them convenience. It's portable, economical and expandable.First of all, all the ways of speech signal processing is well analyzed in the paper. Based on that, a design scheme and an algorithm for speech recognition control system for prosthetic hand have been established.Secondly, all the chips for speech signal processing are well analyzed and a chip for speech recognition control system for prosthetic hand has been chosen. Then hardware for speech recognition control system for prosthetic hand has been finished. We also finish the man-machine communication program to be convenient for debugging. Aiming at the shortcomings of the system that emerge in course of experiment and debugging, we complete the improvement design of the speech recognition control system for prosthetic hand. We also finish the shell design of the system and make it an integrated production.Thirdly, the principle of the algorithm for speech recognition control system for prosthetic hand is introduced. Software for the system is designed, included speech recognition program and wireless communication program. We also finish the shell design of the system and make it an integrated production. Finally, we make experiments of the speech recognition control system for prosthetic hand. The experiments prove that the hardware and software is competent for the system and can meet the demands of the design.
