Abstract

Human voice directivity shows horizontal asymmetries caused by the shape of the lips or the position of the tooth and tongue during vocalization. This study presents and analyzes the asymmetries of voice directivity datasets of 23 different phonemes. The asymmetries were determined from datasets obtained in previous measurements with 13 subjects in a surrounding spherical microphone array. The results show that asymmetries are inherent to human voice production and that they differ between the phoneme groups with the strongest effect on the [s], the [l], and the nasals [m], [n], and [ŋ]. The least asymmetries were found for the plosives.

摘要

人类语音的指向性会表现出水平不对称性，这是由发声时嘴唇的形状或牙齿和舌头的位置造成的。本研究提出并分析了 23 个不同音素的语音指向性数据集的不对称性。这些不对称性是从之前在一个环绕球形麦克风阵列中对 13 个受试者进行的测量中获得的数据集中确定的。结果表明，不对称性是人类语音产生的固有特性，并且它们在音素组之间存在差异，其中对[s]、[l]和鼻音[m]、[n]和[ŋ]的影响最大。在爆发音中发现的不对称性最小。
