在英语中，信息结构在决定短语的突出性和核音高的分配中起着重要的作用。早期的研究声称，话语中的新单词或重点单词会有突出的高/升音，而给定的单词则没有重读，突出度降低。实证研究结果各不相同，但描绘了一幅更复杂的信息结构韵律编码的图景。本文从中性和活泼情绪下的语音阅读出发，研究了美国英语中核位信息状态和对比焦点的语音编码。给定的信息与减少的语音和语音突出有关，对比信息与增强的突出有关，而新信息对应于增加的语音突出，而不是语音突出，如评估音高口音类型，持续时间，强度和语音质量。结果表明，信息结构与核音重音类型之间存在概率关系，信息结构在声突出中的梯度表达。
Information structure is said to play an important role in determining phrasal prominence and the assignment of nuclear pitch accents in English. Early accounts claim that discourse-new or focused words receive a prominence-lending high/rising pitch accent, while given words are unaccented, with reduced prominence. Empirical findings are varied, but paint a more complex picture of the prosodic encoding of information structure. The present study investigated the phonological and phonetic encoding of information status and contrastive focus in nuclear position in American English, from speech read under neutral and lively affect. Given information was associated with decreased phonological and phonetic prominence, contrastive information with enhanced prominence, while new information corresponded to increased phonological, but not phonetic prominence, as assessed in pitch accent type, duration, intensity, and voice quality. The findings indicate a probabilistic relationship between information structure and nuclear pitch accent type, and gradient expression of information structure in acoustic prominence.
