语音震颤对元音声学特性的影响：一个计算建模研究

Voice tremor in the acoustic speech signal may arise from multiple sources of modulation. The present study focused on vocal tract tremor, in which a localized region of the vocal tract is modulated sinusoidally in cross-sectional area, resulting in time-varying perturbations of the vocal tract resonance frequencies. The first aim was to quantify the effects of vocal tract tremor on the first three resonance frequencies as a function of tremor location and spatial extent. Using computational models of male and female vocal tracts configured for a neutral vowel, /a/, /i/, and /u/, sinusoidal tr
