Speech perception is remarkably robust. This paper examines how acoustic and auditory properties of vowels and consonants help to ensure intelligibility. First, the source-filter theory of speech production is briefly described, and the relationship between vocal-tract properties and formant patterns is demonstrated for some commonly occurring vowels. Next, two accounts of the structure of preferred sound inventories, quantal theory and dispersion theory, are described and some of their limitations are noted. Finally, it is suggested that certain aspects of quantal and dispersion theories can be unified in a principled way so as to achieve reasonable predictive accuracy.
语音感知具有显著的稳健性。本文探讨元音和辅音的声学及听觉特性如何有助于确保可懂度。首先，简要描述语音产生的源 - 滤波器理论，并针对一些常见元音展示声道特性与共振峰模式之间的关系。接下来，描述了关于优选音素库结构的两种理论——量子理论和离散理论，并指出它们的一些局限性。最后，有人提出量子理论和离散理论的某些方面可以以一种有原则的方式统一起来，以达到合理的预测准确性。
