汉语双音节词VCV序列协同发音

Coarticulatory effect in VCV sequences in Chinese

该文通过分析跨音段情况下前音节元音对后音节元音第二共振峰F2起点的影响,考察了汉语普通话双音节词"元音-塞音-元音"序列中2个元音之间的协同发音现象。结果发现:当2个元音之间为送气塞音时,由于送气塞音时值较长,元音间的协同发音作用便比较小,送气是抑制协同发音作用的重要因素;在塞音发音部位方面,当后接元音为/i/时,跨唇音的协同作用较大,而跨舌尖音的协同作用较小,不过发音部位与后接元音的交互作用很大,超过发音部位单方面的作用。

The V-to-V coarticulatory effect in VCV sequences involves trans-segmental effects on the onset values of the second formant（F2） by the foregoing vowels on the following ones.However,due to the long temporal separation between vowels for aspirated stops,coarticulation has little effect in the aspirated stops since aspiration is a prominent factor in blocking coarticulation.The effect of the stop place is seen with coarticulation extent of the labial exceeding that of the alveolar in the fixed vowel context of /i/.However,the interactive effect of the place of articulation and the fixed vowel context is stronger than the effect of the stop place.
