Development of mechanical model for generating pathlogical voice

在本研究中，我们利用机械语音产生模型来研究病理语音产生的机制。为此，我们开发了一个机械声带模型，模仿病理声带的几何形状及其喉部控制结构。利用该模型，对不同形状、喉控制不平衡的各种声带模型进行病理性声带振动再现。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.
