One of the substitute voices of laryngectomy patients is the fluty-type artificial larynx. This is a device that uses your breath. This device has the problems of blocking both hands and making the sound monotonous. The purpose of this study is to solve this problem by using a blower instead of human breath. For acoustic analysis of the artificial larynx, we modeled the air inside it as concentrated masses connected by linear springs and dampers. The validity of the proposed method is confirmed by the results of numerical simulation and experimental. We confirmed that the effects of periodic and chaotic sounds on naturalness. Also, we confirmed the difference in naturalness when sound sources were instead from the lip side and glottis side.
