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。
Based on the prosodic words in Putonghua statements obtained from the corpus, this dissertation examines the specific expressions of pitch-dip within prosodic words. By comparing the pitch declination of multi-syllable prosodic words in different positions of prosodic phrases, we find that as the number of prosodic word syllables increases, the pitch declination within prosodic words gradually increases. Pitch down includes not only pitch down the pitch, but also includes pitch down the slope. Downward inclination is significantly greater than the on-line inclination. In different positions of the prosodic phrase, these two kinds of downtilts have different manifestations. In the prosodic phrase at the beginning and end of the position, down the line more pronounced.
