| Research Abstract |
In this research, we investigate mechanism of pathological voice generation by means of mechanical speech production model. For this purpose, we develop a mechanical vocal cord model mimicking geometrical shape of pathological vocal cords and its laryngeal control structure. By using the model, we reproduce pathological vocal cord vibration for various vocal cord models with different shape and unbalanced laryngeal control. Then, we investigate the relationship between the geometrical and control parameters of the model and the characteristics of the vocal cord vibration and the acoustic consequence.
