摘　　要：本文考察了语篇修辞层级结构边界的韵律表现。对由20个语篇构成的语料库进行了修辞结构的层级标注和声学分析。声学参数主要采用小句边界处无声段,音高重置和边界前音节延长。研究得到以下主要结论:(1)小句边界处无声段和高音点重置是语篇修辞层级结构的主要声学线索。小句边界在语篇层级结构中的位置越高,边界处无声段越长,边界处高音点重置的值越大。但是语篇结构中小句边界处的无声段延长和高音点重置增大也是有限度的。(2)小句边界处低音点重置和边界前音节延长都不是区分语篇修辞层级结构的有效线索。This paper investigates the prosodic reflection of rhetorical structures in Chinese texts.A corpus of twenty oral texts that had been read aloud was annotated based on the rhetorical structure theory(RST) and was then acoustically analyzed.The prosodic features included pause duration,pitch reset and pre-boundary lengthening.The results show that both pause duration and top line reset are reliable indicators of the rhetorical structure of texts.Their values increase as the position of the segment climbs up the rhetorical hierarchy,with some limitations.Bottom line reset and pre-boundary lengthening are found to not be valid indicators of the rhetorical structure of texts.

关 键 词：修辞结构 无声段 音高重置 边界前音节延长
