本文考察了北京话单音节中音质层面各音素间协同发音作用在元音鼻化度上的反映以及超音质层面上声调对元音鼻化度的影响。结果发现:1.清辅音声母的发音部位和方法会对元音的内在鼻化度大小产生影响,增大或减小因元音而异。2.鼻音使元音的复合鼻化度显著提高,清辅音声母音节中的元音复合鼻化度稍有降低,边通音/l/、/r/通音声母音节中元音复合鼻化度最低。3.不同声调对元音内在鼻化度、元音复合鼻化度都有影响,且具有一致性。4.元音内在鼻化度的大小既受舌位高低影响,也受舌位前后影响,但与时长、音强无关。以上表现男女发音人有差异,但差异不显著。文章还讨论了与元音内在鼻化度相关的问题。
This paper examines the effect of synergistic pronunciation between the phonemes in the phonemic syllables of Beijing Mandarin on the vocalization of vowels and the influence of tone on the vocalization of vowels at the ultrasonics level. The results showed that: 1. Clear consonants consonants of the pronunciation site and method will vowel internal nasal degree of size have an impact, increase or decrease due to vowel differences. Nasal consonants markedly increased the composite nasalization of vowels, and the vowel compound nasalization degree in the consonant consonant of Qing consonant decreased slightly. The vowel compound nasal consonants in the vowel / l /, / r / vowel consonants Degree of the lowest. 3. Different tonal vowel internal nasal degree, vowel compound nasal degree have an impact, and consistent. 4. vowel internal nasal degree of both the size of the tongue by the level of influence, but also by the tongue before and after the impact, but with the length of time, sound intensity has nothing to do. The performance of male and female pronunciation of the above differences, but the difference was not significant. The article also discusses the issues related to intrinsic nasalization of vowels.
