普通话自然独白话语两音节韵律词的重音分析

On the Stress Patterns of Disyllabic Prosodic Words in Mandarin Monologue

通过感知实验和声学分析对汉语普通话自然独白话语的两音节韵律词的不同重音类型(前重和后重)的音高和时长特征进行研究,发现两音节韵律词的词重音类型以前重类型居多。声调起点音高的类型、停顿和音高重设现象在重音的感知听辨中很重要。在不同的韵律层级结构边界前,重读音节的特点都是音高的上限和下限提高,但是音高域不扩大,与此同时,时长会出现加长的现象。

The paper analyzes the duration and pitch of the accented syllable in disyllabic prosodic words of Mandarin monologue through perception experiment and acoustic analysis.The left syllable tends to be perceived as the accented one by listeners in the perception test.The high tone and the falling tone with high pitch onset are more easily perceived as accented.Besides the contributing factors such as onset,pause and pitch resetting,the pitch floor and the pitch ceiling of accented syllables are raised,and the normalized duration of accented syllables are lengthened before different prosodic hierarchical boundaries,whereas the pitch range of accented syllables is not expanded.
