【摘要】：本文将普通话两音节轻声词和其对立的非轻声词置于五种不同的信息结构中,分析了轻声的语音产出编码方式。研究使用了一些新的语音特征,如描写声调调形的斜率特征、谐噪比等特征。统计分析发现,轻声的声学特征与信息结构、轻声前字调和轻声底层调等相关。在这些特征中,音高和时长的作用最大;在单念的时候,音高的作用大于时长;在语流中,轻声相关量不但与信息结构相关,还与轻声的底层调相关。另外一个发现是,与非轻声词相比,轻声词除了轻声音节的音高变化外,其前字音域明显拉大,从而使得前后音节产生更大的轻重对比。
[Abstract]:In this paper, two syllable soft words in Putonghua and their opposite non-whisper words are placed in five different information structures, and the speech output coding method of soft voice is analyzed. Some new phonetic features are used, such as slope feature of tone modulation, harmonic noise ratio and so on. The statistical analysis shows that the acoustic characteristics of the soft voice are related to the information structure, the front word of the light voice and the lower tone of the light voice. In these features, pitch and duration play the most important role; in single reading, pitch plays a greater role than duration; in the flow, the correlation is not only related to the information structure, but also to the underlying tone of the softly spoken voice. Another finding is that, in addition to the change of the pitch of the whispering syllable, the range of the antecedent is obviously larger than that of the non-whisper, which makes the pronoun and the former syllable more light and heavy.
