扬州方言入声区别性特征的感知研究

Perceptual Studies on the Distinctive Features of Rusheng 入声 Tone in Yangzhou Dialect,Jiangsu Province

声学实验显示扬州方言入声与去声的单字调调值重合,时长有别,当地人可有效区分。本文分别改变去声-入声的时长信息和基频信息,进行感知实验,得出结论:(1)时长是感知入声的区别性特征;(2)喉塞尾不是入声感知的必备条件,但可提高入声感知的辨认度。

Acoustic experiments shows that the monosyllables of Rusheng 入声 and Qusheng tones in Yangzhou dialect, Jiangsu province are coincident in tone value while their durations different. Natives in Yangzhou can well distinguish the two tones. The paper modifies the duration and fundamental frequency of the two tones through perceptual experiment and draws the following conclusions： （1） Duration is the key distinctive feature in Rusheng 入声 perception. （2） Beneficial as it may be, the glottal stop is not the necessary condition for the Rusheng 入声 perception.
