语音语调研究的一个中心问题是基频（f（0））变化与语音范畴的关系。假设被测试，音高范围的变化，影响是否一个音节是高于或低于另一个会引起分类移位的f（0）极值计时在模仿任务。参与者听到合成版本的短语Some lemonade，带有上升-下降或下降-上升语调，以及le-和mo-之间的平坦f（0）轮廓。le-和mo-的f（0）水平是变化的，因此对于一半的刺激，le-的f（0）高于mo-，而其余的则相反。参与者在刺激中具有平坦f（0）的音节上产生fo峰和谷;极值类型（峰或谷）及其时间对齐随刺激中le-和mo-的相对fo水平而变化。最后，本文根据语调音系学的理论对结果进行了讨论。它表明，这些结果的帐户下autosegmental-metric理论（例如，Pierrehumbert，J.（1980年）。英语语调的音系学和语音学。博士dissertation，MIT，剑桥，MA）需要在f（0）的语音模型中设定附加约束。Pierrehumbert和Beckman [（1988）.日语的声调结构。马萨诸塞州剑桥：因此，提出了[MIT Press]的语音模型，该模型假设了对相对音调高度的附加约束和音调之间的严格单调插值。(C)2007爱思唯尔有限公司保留所有权利。
A central issue in speech intonation research concerns how fundamental frequency (f(0)) variation relates to phonological categories. The hypothesis was tested that pitch range variation which affects whether one syllable is higher or lower than another would elicit categorical shifts in f(0) extremum timing in an imitation task. Participants heard synthetic versions of the phrase Some lemonade with rising-falling or falling-rising intonation and flat f(0) contours across le- and mo-. The f(0) levels of le- and mo- were varied such that for half the stimuli, le- had a higher f(0) than mo-, while the reverse was true for the remainder. Participants produced fo peaks and valleys on syllables that had flat f(0) in stimuli; extremum types (peaks or valleys) and their temporal alignments varied categorically with the relative fo levels of le- and mo- in the stimuli. The results are discussed in terms of theories of intonational phonology. It is shown that an account of these results under autosegmental-metrical theory (e.g., Pierrehumbert, J. (1980). The phonology and phonetics of English intonation. Ph.D. dissertation, MIT, Cambridge, MA) requires positing additional constraints in phonetic models of f(0). A revised version of the Pierrehumbert and Beckman [(1988). Japanese tone structure. Cambridge, MA: MIT Press] phonetic model is therefore proposed which assumes additional constraints on relative tone heights and strictly monotonic interpolation between tones. (C) 2007 Elsevier Ltd.
