本研究旨在探讨语音动力学，特别是喉内声门流的不稳定运动。为了只关注流体运动，假设声带是非振动的刚体，尽管声门声源被描述为流体和振动声带之间的相互作用。声门流的基础上的二维刚体模型是通过求解基本方程的可压缩粘性流体，受到适当的初始和边界条件。计算结果表明，初始声门流为简单的对称射流，随后转变为二维非定常的复杂流场。此外，复杂流的结构随时间而变化。这些结果表明，简单的假设，如线性化的流体方程或一维模型，是不合适的语音产生过程的分析。
The present study is intended as an investigation of speech dynamics, particularly the unsteady motion of glottal flow in the larynx. In order to focus on only fluid motion, the vocal cords are assumed to be non-vibrating rigid bodies, although the glottal sound source is described as the interaction between the flow and the vibrating vocal cords. The glottal flow based on the two-dimensional rigid body model is simulated by solving basic equations in a compressible viscous fluid that is subject to appropriate initial and boundary conditions. The obtained results demonstrate that the initial glottal flow was a simple symmetric jet and that the flow became an unsteady complicated flow with vortices distributed in two-dimensional space. Furthermore, the structure of the complicated flow changed with time. These results indicate that simple assumptions, such as linearization of the fluid equations or one-dimensional models, are inappropriate for analysis of the speech production process.
