Development of mechanical model for generating pathlogical voice

本研究通过机械语音产生模型来探讨病理性语音产生的机制。为此，我们开发了一个机械声带模型模仿几何形状的病理声带及其喉控制结构。利用该模型，我们对不同形状和喉部控制不平衡的声带模型进行了病理性声带振动的再现。然后，我们研究了模型的几何参数和控制参数与声带振动特性和声学后果之间的关系。

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.
