平遥方言单音节响音的鼻化度初探

Analysis of Sound Nasality of Monosyllables on Sonorant in Pingyao Dialect

使用鼻音计对平遥方言浊声母和一级元音鼻化度的分析结果表明:除"部分鼻音"/nz/外,平遥鼻音声母的鼻化度很高,并能大幅提高其后韵母部分的鼻化度;而非鼻音浊声母的鼻化度不高,对于提高后接元音鼻化度的作用也不明显。一级元音的内在鼻化度根据舌位前后和唇型的不同而不同,舌位越前,唇型越展,鼻化度越高;反之鼻化度越低。此外,韵腹/a/能显著降低/-耷/韵尾的鼻化度,其他韵腹元音对/-耷/韵尾的鼻化度影响不大。

Using the Nasometer, this paper analyzed the nasality degree of the voiced initials and the first class vowels in Pingyao dialect. The results showed that except the ＂partial nasality＂/nz/, the nasality degree was very high, and it could heighten the nasality degree of the vowels after them. The other sonorants had low nasality degree, which could not heighten vowels＇ nasality degree. The nasality degree of the first vowel was different when it had the different position of the tongue and type of the lip. Besides,/a/could reduce the nasality degree of/-N/, while other vowels couldn＇t.
