Abstract

The Maeda model was used to generate a large set of vocoid-producing vocal tract configurations. The resulting dataset (a) produced a comprehensive range of formant frequencies and (b) displayed discrete tongue body constriction locations (palatal, velar/uvular, and lower pharyngeal). The discrete parameterization of constriction location across the vowel space suggests this is likely a fundamental characteristic of the human vocal tract, and not limited to any specific set of vowel contrasts. These findings suggest that in addition to established articulatory-acoustic constraints, fundamental biomechanical constraints of the vocal tract may also explain such discreteness.

摘要

前田模型被用于生成大量产生元音的声道构型。所得数据集（a）产生了全面的共振峰频率范围，并且（b）显示了离散的舌体收缩位置（腭部、软腭/小舌和下咽）。整个元音空间中收缩位置的离散参数化表明，这可能是人类声道的一个基本特征，而不限于任何特定的元音对比集。这些发现表明，除了已确立的发音-声学限制外，声道的基本生物力学限制也可能解释这种离散性。
