Cross-Language Study of Perception of Coarticulated Speech

9319597过去25年来收集的关于言语产生和知觉的贝多摘要跨语言数据表明，语言在协同发音模式和知觉组织方面可能存在系统性的不同。这一建议的核心问题是，言语感知中的语言差异是否与协同发音结构中的语言差异有关。需要检验的具体假设是，语言特有的协同发音模式会引起听者对协同发音的声学后果的期望；这种期望反过来又会导致语言特有的知觉适应协同发音的模式。这里收集的跨语言声学和知觉数据与言语感知和语言习得的理论问题有关。目前的言语感知模型的不同之处在于，感知的基元是听觉事件还是声道手势。如果发现补偿性语境效应是特定于语言的(反过来又与特定于语言的协同发音模式有关)，就会限制可能的模型。反对这些影响的纯听觉来源，也反对发音手势方法，后者认为声音信号为听者提供了足够的信息来分离共同发音影响。言语知觉的发展模型更多地关注特定于语言的初始知觉能力的重组。即使关于协同发音-知觉联系的具体假设不被支持，数据也将拓宽关于哪些知觉能力可以通过语言经验和相关经验的性质来修改的知识。***

9319597 Beddor ABSTRACT Cross-language data on speech production and perception gathered over the past 25 years show that languages may systematically differ in both coarticulatory patterns and perceptual organization. The central question addressed by this proposal is whether language differences in speech perception are linked to language differences in coarticulatory structure. The specific hypothesis to be tested is that language-specific patterns of coarticulation give rise to listener expectations concerning the acoustic consequences of coarticulation; such expectations in turn lead to language-specific patterns of perceptual accommodation to coarticulated speech. The cross-language acoustic and perceptual data to be collected here are relevant to theoretical issues in speech perception and language acquisition. Current models of speech perception differ in whether the primatives of perception are auditory events or vocal- tract gestures. A finding that compensatory context effects are language-specific (and in turn linked to language-specific coarticulatory patterns) would constrain possible models. It would be argued against a purely auditory source for these effects, but also against articulatory-gesture approaches which propose that the acoustic signal provides sufficient information for the listener to disentangle coarticulatory influences. Developmental models of speech perception are more centrally concerned with the language- specific reorganization of initial perceptual capabilities. Even if the specific hypotheses concerning a coarticulation-perception link are not upheld, the data will broaden knowledge of which perceptual capabilities can be modified through linguistic experience and the nature of the relevant experience. ***
