The present paper explores the textual function of intonation in indicating coherence and boundaries between successive utterances of speech. An informal listening test showed how such prosodic coupling can be used to mark coherence between sentences of a text unit. The coherence is expressed as a downdrift of F0 peaks and valleys characterizing the whole text unit. The boundary between two text units is signalled by terminating one and beginning another downdrift ramp. The characteristic features of the downdrift pattern seem to be (1) an adjustment of F0 values to the length of the text unit, and (2) an adaptation of the F0 of the beginning of a succeeding sentence to that of the later part of a preceding one in the same unit. Some preliminary implications of these results for speech planning are discussed.
本文探讨了语调在指示连续话语之间的连贯性和界限方面的文本功能。一项非正式听力测试展示了这种韵律耦合如何用于标记文本单元中句子之间的连贯性。连贯性表现为表征整个文本单元的F0峰值和谷值的下降趋势。两个文本单元之间的界限通过一个下降趋势的结束和另一个下降趋势的开始来表示。下降趋势模式的特征似乎是：（1）F0值根据文本单元的长度进行调整；（2）后续句子开头的F0与同一单元中前一个句子后半部分的F0相适配。文中还讨论了这些结果对言语规划的一些初步启示。
