The electric prosthetic hand has not been spread throughout Japan. The authors have developed a novel myoelectric prosthetic hand based on survey responses on demand for prosthetic hands. The prosthetic hand is controlled by surface electromyogram signals (sEMG) of forearm. The signals are input into a neural network that estimates the joint angles of five fingers. The system may not obtain enough sEMG signals to control the prosthetic hand from the amputees. This paper proposes a new control system of the prosthetic hand that using voice and sEMG signals. The system allows amputees to control the grasping force and to hold the object without sEMG signals. To demonstrate the effectiveness of the system, a normal subject controls the prosthetic hand using voice and sEMG signals.
