摘要
采用实验语音学的方法,考察了语篇焦点的声学表现是否受到语篇修辞层级的调节。六位普通发音人朗读了32组实验材料,处于不同层级焦点词的时长、音域、高音点和低音点分别被提取出来做统计分析。结果发现,处于高层级的焦点词时长更长,音域更宽;同时,随着声调组合的变化,不同层级焦点词的高音点和低音点呈现不同的特征,具体体现在对于不含上声的焦点词,高层级焦点词的高音点更高,而对于含上声的焦点词,高层级焦点词的低音点更低。
Phonetic experiments were carried out to investigate whether the acoustic features of discourse focus were subjected to the influence of discourse hierarchy. Six speakers were instructed to read aloud 32 groups of experimental material. The duration, pitch range, f0 maximum, and f0 minimum of foci in different discourse hierarchy were extracted for statistical analysis. The results revealed that foci embedded higher in the discourse hierarchy had relatively longer duration and more expanded pitch range; moreover, with the variation of tone combination, foci of different discourse hierarchy differed remarkably in their manifestation of f0 maximum and f0 minimum features. Specifically speaking, for non-low tone combinations, foci in higher discourse hierarchy were notably characterized by higher f0 maximum, while for low-tone combinations, loci in higher discourse hierarchy were signaled by lower f0 minimum.
