汉语句子的韵律结构
Temporal structures of spoken Chinese sentences
-
摘要: 为进一步深入研究汉语韵律特征在时间维上的表现,特别录制了一个语音资料库。发音人共10名(5男5女),试验材料包括3个不同语法结构和逻辑结构的句子。发音人以3种不同的语速自然朗读,相隔几周之后重复发音,总共3次。采用语音分析专用软件SFS(Speech File System)进行时间-频率分析,试验结果表明:(1)语速变化时,句子重音和句调保持不变,(2)语速加快时,尾部成分的相对时长加大,(3)语速加快时音节调型可发生很大变化,(4)停顿不但可用于表现句法结构,而是在语速变化时起着时长上的调节作用,(5)在语速变化时,语音中有些音段(多数元音)是弹性较大的,容易被压缩或伸展,有些音段是比较稳定的,不是被压缩或伸展。Abstract: The tempo and prosodic pattern in Chinese were investigated further. A special speech database, which was composed of three compound sentences and ten speakers (5 males and 5 females), was created. Three test sentences have different grammatical structures. The results show that: 1. The sentence prominence and the sentence intonation are invariant prosodic features; 2. The tonal pattern can be influenced by tone coarticulation and speech mood; 3. The effect of last constituent lengthening in relative duration in fast speech is not a kind of syntactic or semantic signal; 4. The pause signals a boundary of phrase and sentence and it will be compressed in fast speech.
