普通话韵律词内部下倾度的初步分析

Declination Analysis of Prosodic Word in Mandarin

本文主要以从语料库中得到的普通话陈述语句中的韵律词为依据,考察了韵律词内部的音高下倾的具体表现。通过对比韵律短语不同位置的多音节韵律词内部的音高下倾度,我们发现,随着韵律词音节数目的增加,韵律词内部的音高下倾度也逐渐增大。音高下倾不仅包括音高上线的下倾,同时也包括音高下线的下倾。下线的下倾度明显大于上线的下倾度。在韵律短语的不同位置,这两种下倾有不同的表现。在韵律短语首和末位置,下线的下倾更为明显。

This paper analyzes the pitch declination within prosodic words which are got from the corpus contained 400 sentences.Contrasted the declination of polysyllabic prosodic word in different position of prosodic phrase,we concluds that:with the syllable number increasing, the pitch declination increases gradually within prosodic words.The pitch declination includes high line and low line,and declination scale of low line is bigger than declination scale of high line.In different positions of prosodic phrase,the performances of two declinations are different.In the middle of prosodic phrase,the declinations of high point and low point are almost the same,but at the initial and the final,low point declination is bigger than high point distinctly.
