维吾尔语辅音丛的发音机制

Articulatory Mechanisms of Consonant Clusters in the Uyghur Language

本文利用动态电子聘位(EPG)语料库,对维吾尔语音节内辅音丛的发音机制进行了研究。研究显示,辅音在发音部位和发音方法上存在发音限制条件的层级关系,即舌面音、擦音的发音限制条件最高,不易受环境辅音的影响,而舌尖音、塞音的发音限制条件最低,故易受影响;辅音丛的发音互适机制有3种,即协同发音、融合和同化。这些发音机制在语音实现的过程中会受到发音限制条件的制约。

In this paper,the authors study the Uyghur syllable-final consonant clusters based on the corpus of electropalatography(EPG).The research shows that there is an inherent hierarchical relationship in terms of manners and places of articulation of consonants forming the clusters.That is,the dorsal and fricative consonants are subjected to a higher degree of articulatory constraints and are not easily affected by surrounding consonants,while the apical and plosive consonants are subjected to the lowest articulatory constraints and are thus easily affected by surrounding consonants.There are three kinds of gestural adaptation mechanisms of consonant clusters,namely,coarticulation,blending as well as assimilation.These mechanisms are restricted by articulatory constraints in the process of phonetic realization.
