本研究的目的是找出同一话语中两个重音音节的基音峰高与不同聚焦条件之间的关系。焦点条件是中性焦点、双对比焦点和单对比焦点在第一个或第二个重音节上。在实验一中，被试调整两个基音峰值中的一个的高度，以使基音轮廓表现出不同的焦点结构。在一个峰的不同固定高度与另一个峰的调整高度之间没有发现系统的关系，这表明与焦点相关的音调峰的目标值的存在。在实验2中，听者判断四种焦点结构中的哪一种最有可能由峰值高度之间的给定关系来表示。结果表明，一些基音轮廓线相对于焦点是模糊的，但大多数轮廓被一致归类为仅表示一种可能的焦点结构。目前的结果也为早期日冕实验中一些无法解释的发现提供了新的线索。
The purpose of the present study is to find out how the pitch peak heights on two pitch-accented syllables in one utterance relate to different focus conditions. The focus conditions are neutral focus, double contrastive focus, and single contrastive focus on either the first or the second pitch-accented syllable. In Experiment 1, subjects adjusted the height of one of two pitch peaks, so as to make the pitch contour express different focus structures. No systematic relationship was found between different fixed heights of one peak and the adjusted heights of the other, which suggests the existence of target values for focus-related pitch peaks. In Experiment 2, listeners judged which of the four focus structures was most likely represented by a given relation between peak heights. The results show that some pitch contours are ambiguous with respect to focus, but the majority of them is classified unanimously as signalling only one possible focus structure. The present results also shed new light on some unexplained findings of earlier prominence experiments.
