线索短语是诸如“现在”和“好”等可以明确标记语篇结构的语言表达。例如，当提示短语“顺便”在句中用作状语时，话语的使用会引发离题。在文献[8]中，我们注意到提示短语在语篇和句子使用方面的歧义性，并提出了一个消除歧义的语调模型。在本文中，我们扩展了我们以前的特征的提示短语和概括其域的覆盖范围，基于一个更大，更全面的实证研究：一个单一的扬声器在记录的自然语音产生的所有提示短语的检查。我们还将这种韵律模型与文本中的提示短语的正字法和词性分析相关联。这样的双重模型既为当前的话语计算模型提供了理论依据，也为合成语音的生成提供了实际应用。
Cue phrases are linguistic expressions such as 'now' and 'well' that may explicitly mark the structure of a discourse. For example, while the cue phrase 'incidentally' may be used SENTENTIALLY as an adverbial, the DISCOURSE use initiates a digression. In [8], we noted the ambiguity of cue phrases with respect to discourse and sentential usage and proposed an intonational model for their disambiguation. In this paper, we extend our previous characterization of cue phrases and generalize its domain of coverage, based on a larger and more comprehensive empirical study: an examination of all cue phrases produced by a single speaker in recorded natural speech. We also associate this prosodic model with orthographic and part-of-speech analyses of cue phrases in text. Such a dual model provides both theoretical justification for current computational models of discourse and practical application to the generation of synthetic speech.
