筋電位信号を用いた食道発声法訓練用システムに関する研究

抄録

The patients who undergo the laryngectomy lose their voice. The voice is very important communication method for human, and these patients become to feel inconvenient. One of the speech producton substitutes for the patients is the esophageal speech, this method uses the air from esophagus to generate the primary tone. This method has good characteristics at voice quality and convenience. But learning of it is very difficult.

In this research, we aim to establish the training method of esophageal speech with bio monitoring. This method uses some muscles for taking in air to the esophagus. Therefore, it is important that the clarification of "when" the "what muscle" is activated in esophageal speech. In this report, we took a survey to esophageal speech users, for clarification of "what muscle" is activated in esophageal speech. Based on these results, the myoelectric signal of the lower jaw and the lowest intercostral were measured. These results are described.
