Abstract 摘要
Acoustic analysis was conducted to identify the acoustic correlates for the place distinction in Mandarin voiceless fricatives. Eleven spectral, amplitude, and duration measures that have been shown to classify fricatives in English were analyzed to evaluate whether they can similarly classify fricatives in Mandarin. The results showed that each place contrast was associated with at least two measures, but no single measure classified all fricatives. The measures that were most effective in classifying fricative place also differed between the two languages. These results were interpreted in terms of the articulatory-acoustic relationship in the context of the acoustic theory of speech production.
本研究针对普通话中清擦音的发音部位进行声学分析。我们从英语擦音的声学文献中找出了十一个与频谱，振幅，及音长有关的声学特征，评估它们是否能有效区别普通话中清擦音的发音部位。分析结果显示，所有的发音部位都至少有两个声学特征可供区别，但没有任何一个声学特征可以区别所有的发音部位。区别普通话发音部位最有效的声学特征也不同于英语。我们运用发音的声学理论来解释这些分析结果。
