字母词对普通话音节结构的改变——字母S、F、H的声学研究

The Changes in Mandarin Syllable Structures Caused by Lettered-words:An Acoustic Phonetic Study of Letter S,F and H

研究采用实验的方法,对比分析了中、美发音人朗读字母词时音节尾的擦音[s][f]和塞擦音[tʃ]的声学特征及发音机制。得到的结论是:字母词已突破了普通话原有的闭音节只以鼻音结尾的结构规则,进而将新音节结构,即以擦音[s]、[f]、塞擦音[tʃ]结尾的闭音节带入普通话;同时,[s][f][tʃ]三个音的COG和DIS参量,以及[tʃ]音的GAP和DOF参量与标准美音仍存在差异。

This paper reports a constrastive study on the acoustic features and articulatory mechanisms of the fricatives[s][f]and the affricate[tʃ]as the coda in lettered-words pronunciation of both Chinese speakers and American speakers.The results show that lettered-words have already broken the traditional rule of syllable structures in Mandarin,which is only the nasal can be used as the coda;meanwhile,the COG and DIS of[s],[f],[tʃ]and the GAP and DOF of[tʃ]show some significant differences with those in standard American pronunciation.
