Abstract

We have been studying an implantable electrolarynx controlled by the EMG of the sternohyoid muscle(SH). Generally, the pitch control methods of the electrolarynx by SH EMG have two types. In the first pitch control method, the pitch of the electrolarynx increases according to the decrease in amplitude of the SH EMG, and vice versa. In the second pitch control method, the pitch of the electrolarynx decreases according to the decrease in amplitude of the SH EMG, and vice versa. We carried out four physiological experiments about two pitch control method. Also, we made two electrolarynges with two type pitch control, and tested those electrolarynges. From the result of the experiments, we found that the developed electrolarynx have a good property by the first pitch control method more than the second pitch control method.
