摘要

以往的实验研究表明,抑制声带的垂直运动可能会降低声源与声道之间的耦合强度。本研究在二维双质量模型与可压缩流动模拟的耦合下,系统地研究了声带垂直运动对声源-滤波器相互作用的影响。结果表明,当允许声带垂直运动时,声带会因夹带第一声道声共振而表现出次谐波振动。限制垂直运动则抑制了这种夹带。这表明声带的垂直运动可能在调节声源与滤波器的相互作用中发挥作用。

Restraining vocal fold vertical motion reduces source-filter interaction in a two-mass model.

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.
