本文基于朗读语音语料库分析不同层级的韵律单元在语流中的边界特征。研究表明,韵律词末尾不会出现可以感知到的无声停顿,其他层级韵律单元末尾会有一定长度的无声停顿,随着韵律单元的层级提高,其后无声停顿的时间就会越长;韵律单元起首音节韵母的时长不受韵律层级的影响,既不会拉长也不会缩短,而韵律单元末尾音节韵母的时长则明显受到韵律层级的影响,韵律词末尾音节韵母时长不会拉长反而缩短,其他层级韵律单元的末尾音节韵母的时长均有不同程度的拉长。
This paper analyzes the boundary features of prosodic elements at different levels based on spoken phonetic corpus. The research shows that there is no perceptible silence at the end of the prosodic word, and a certain length of silent pause at the end of the prosodic cells at other levels. As the level of the prosodic unit increases, the duration of the silent pause will be longer. The prosodic unit The vowel vowel duration is not influenced by the rhythm level, it neither elongates nor shortens, but the vowel vowel duration at the end of the rhythm unit is obviously influenced by the rhythm level, and the syllable vowel duration at the end of the prosodic word will not be elongated Shorten the duration of the syllable vowel at the end of rhythm units of other levels have different degrees of elongation.
