本文主要对汉语鼻音韵尾的实验研究进行了梳理,包括单音节和语流中汉语鼻音韵尾的声学表现。分析了鼻音韵尾弱化的规律,认为鼻音韵尾的弱化与前临元音舌位的高低、鼻音韵尾本身的前后位置具有一定的关系。简略地讨论了共时的实验研究与历时的演化现象之间的关系。
This paper mainly reviews the experimental research on the Chinese nasal vowels, including the monophonic syllables and the acoustical performance of the Chinese nasal vowels. The weakening of nasal vowel is analyzed, and the weakening of nasal vowel is related to the level of frontal vowel tongue and the position of nasal vowel before and after itself. The relationship between synchronic experimental studies and diachronic evolutions is briefly discussed.
