DESCRIPTION (provided by applicant): As research in speech production becomes more integrated with linguistic theory, it has become increasingly clear that segmental articulation cannot be understood independently of prosodic structure; such structure includes, but is not limited to, accent and phrasal organization. These high-level prosodic aspects of language pervade low-level articulatory behavior. Despite the pervasiveness of these effects, only a very few prosodic signatures have been identified at the level of articulatory patterning. The long term objective of the proposed research program is to understand how linguistic structure conditions the spatiotemporal realization of speech. Specifically, we investigate the relation between one aspect of prosodic structure -- phrasal structure -- and the control and coordination of articulation within a dynamical systems model of speech production. We adopt a three-pronged approach: experimental, theoretical, and computational. Experiments using articulatory kinematic data and concomitant computational modeling of their results will provide a profile of the manner in which patterning of articulatory gestures is shaped by prosodic context. Understanding the organization of these units of speech production as a function of the informational composition of utterances is critical to developing a unified account of the how abstract linguistic structure is communicated in spoken language. Hence, the research program will provide valuable insight into disorders, such as apraxia, that affect language production at the articulatory level, and it will contribute to a better understanding of prosody for speech recognition and synthesis purposes, also of importance to those with communication disorders.

描述（由申请人提供）：随着语音产生的研究与语言学理论的结合，越来越清楚的是，音段清晰度不能独立于韵律结构来理解;这种结构包括但不限于重音和短语组织。语言的这些高级韵律方面渗透到低级发音行为中。尽管这些影响的普遍性，只有很少的韵律签名已被确定在发音模式的水平。该研究计划的长期目标是了解语言结构如何影响语音的时空实现。具体来说，我们调查的韵律结构的一个方面-短语结构-和语音生产的动力系统模型内的控制和协调的清晰度之间的关系。我们采用三管齐下的方法：实验，理论和计算。实验使用发音运动学数据和伴随的计算建模的结果将提供一个配置文件的方式，其中发音手势的图案是由韵律的背景下形成的。理解这些言语产生单位的组织作为话语的信息组成的函数，对于发展抽象语言结构如何在口语中传达的统一解释至关重要。因此，该研究计划将提供有价值的洞察障碍，如失用症，影响发音水平的语言产生，它将有助于更好地理解语音识别和合成目的的韵律，这对那些有沟通障碍的人也很重要。
