Paths to Phonological Complexity: Onset clusters in speech production, perception, and disorders

我们的建议的主要目的是显著推进我们的知识，语言产生，运动控制和感知的普遍方面是如何由世界语言之间的语法差异形成的。我们建议跨语言研究语音产生的偏好模式的本质，它们的感知和它们在言语障碍中的表现。我们利用了四种语言（日语、法语、德语、格鲁吉亚语）之间的韵律和语音差异，以及一种语言两种语言障碍（失用症、失语症）之间的错误模式差异。我们进一步考虑到电机优化的出现。迄今为止还没有这样全面的跨语言研究。进一步的创新潜力来自于考虑语言之间发音时间（辅音重叠）的差异，以及时间差异对优选生产模式出现的条件和如何感知这些模式的影响。通过考虑偏好生产模式的感知可恢复性，我们拓宽了对生理偏好如何反映在语法中的理解。此外，我们从语言失用和失语症的角度考虑普遍偏好和学习行为的相互作用，这为语音复杂性的认知和运动/知觉成分提供了新的见解，并挑战了失语症语音障碍的抽象主义理论。这项工作将为我们理解人类言语和语言的一个主要方面奠定基础：世界语言的多样性是如何从共同的认知和生理基础产生的。

The principal aim of our proposal is to significantly advance our knowledge of how universal aspects of speech production, motor control and perception are shaped by grammatical differences between the languages of the world. We propose a cross-linguistic study into the nature of preferred patterns in speech production, their perception and their manifestation in disordered speech. We capitalize on prosodic and phonotactic differences between four languages (Japanese, French, German, Georgian), and, for a single language, on error pattern differences between two types of speech disorders (apraxia, aphasia). We further take the emergence of motor optimization into account. No such comprehensive cross-linguistic study exists to date. Further innovative potential comes from considering differences in articulatory timing (consonant overlap) between languages and the impact timing differences have on the conditions in which preferred production patterns emerge and how these patterns are perceived. By considering the perceptual recoverability of preferred production patterns we broaden our understanding of how physiological preferences may be reflected in grammar. In addition, we consider the interplay of universal preferences and learned behavior in the light of apraxia of speech and aphasia, which allows for new insights into the cognitive and motoric/perceptual components of phonological complexity, and challenges abstractionist theories of aphasic phonological impairment. This work will be foundational for our understanding of one of the major aspects of human speech and language: how the diversity of the world's languages arises from a common cognitive and physiological basis.
