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

我们的建议的主要目的是显着推进我们的知识，如何言语生产，运动控制和感知的普遍方面是由世界语言之间的语法差异形成的。我们提出了一个跨语言的研究，在语音生产，他们的感知和他们的表现在无序的语音的首选模式的性质。我们利用四种语言（日语，法语，德语，格鲁吉亚语）之间的韵律和音位差异，并为一种语言，两种类型的言语障碍（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。到目前为止，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不同语言之间的发音时间（辅音重叠）的差异，以及时间差异对首选生产模式出现的条件以及这些模式如何被感知的影响。通过考虑知觉可恢复性的首选生产模式，我们扩大了我们的理解，生理偏好可能会反映在语法。此外，我们认为普遍的偏好和学习行为的相互作用，在光的言语失用症和失语症，这使得新的见解的认知和运动/感知组件的语音复杂性，并挑战抽象理论的失语症语音损伤。这项工作将为我们理解人类语言的一个主要方面奠定基础：世界语言的多样性如何产生于共同的认知和生理基础。

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.
