越南语元音格局分布探究

On the Distribution of Vowel Patterns in Vietnamese

本文采用声学分析的方法探索越南语元音的格局分布,通过分析发现,越南语元音格局具有相对的独立性,一级元音丰富且分布呈规律性,层级性强。元音格局由三个外缘性元音[i]、[u]、[a]构成,且[i][u]较[a]的集中程度高。越南语一级元音中的中元音数量较多,共有[e]、[■]、[o]、[■]、[■]、[■]6个,它们在高低维上分级分布,具有较好的层级性,其中[e]、[■]位于/ia/连线处,[o]、[■]位于/ua/连线处元音[■]、[■]位于元音格局框架内部。中元音普遍存在离散度较高的现象。

This paper explores the pattern distribution of Vietnamese vowels by means of acoustic analysis.Through the analysis,it is found that the pattern of Vietnamese vowels is relatively independent,and the first-order vowels are rich and regularly distributed,with strong hierarchy.The vowel pattern consists of three peripheral vowels[i],[u],[a],and the concentration of[i][u]is higher than that of(a)There are more middle vowels in the first-level vowels of Vietnamese.There are 6[e],[■],[o],[?],[■],[w]middle vowels in the first-level vowels of Vietnamese.They are graded and distributed in high and low dimensions,and have better hierarchy.Among them,[e],[?]are located at/ia/line,[o],[?]are located at/ua/line,[■],[■]are located in the middle of the vowel pattern.The phenomenon of high dispersion of vowels is common in Chinese vowels.
