Abstract

Previous experimental studies suggested that restraining the vocal fold vertical motion may reduce the coupling strength between the voice source and vocal tract. In this study, the effects of vocal fold vertical motion on source-filter interaction were systematically examined in a two-dimensional two-mass model coupled to a compressible flow simulation. The results showed that when allowed to move vertically, the vocal folds exhibited subharmonic vibration due to entrainment to the first vocal tract acoustic resonance. Restraining the vertical motion suppressed this entrainment. This indicates that the vertical mobility of the vocal folds may play a role in regulating source-filter interaction.

摘要

先前的实验研究表明，限制声带的垂直运动可以降低声源和声道之间的耦合强度。在这项研究中，我们在一个二维双质量模型与可压缩流模拟耦合的系统中，对声带垂直运动对源滤波器相互作用的影响进行了系统的研究。结果表明，当允许声带垂直运动时，由于与第一声道声共振的同步，声带会出现亚谐波振动。限制垂直运动抑制了这种同步。这表明声带的垂直运动能力可能在调节源滤波器相互作用方面发挥作用。
