| Research Abstract |
In this study, I investigated an artificial larynx meant for patients who have lost their vocal cords because of laryngeal injury or laryngeal cancer. This artificial larynx has a piezoceramic sounder as the sound source. It has a disadvantage that its sound is different from the sound from the human vocal cord. I attempted to improve its sound quality by shape optimization. In addition, I attempted to improve the voice articulation by controlling the pitch frequency and on-off. For this, I focused on the neck myoelectric potential and a control method based on biosignals.
