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(申请人提供)：随着言语产生的研究与语言学理论的日益结合，人们越来越清楚地认识到，分段发音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的组织。这些高级韵律方面的语言普遍存在于低级发音行为中。尽管这些影响无处不在，但在发音模式水平上，只有极少数韵律特征被识别出来。该研究计划的长期目标是了解语言结构是如何制约语音的时空实现的。具体地说，我们研究了韵律结构的一个方面--短语结构--与语音产生的动态系统模型中发音的控制和协调之间的关系。我们采取了三管齐下的方法：实验、理论和计算。使用发音运动学数据的实验及其结果的伴随计算建模将提供发音手势的模式被韵律语境塑造的方式的轮廓。理解这些言语产生单位的组织作为话语的信息构成的功能，对于建立一个关于抽象语言结构如何在口语中交流的统一描述是至关重要的。因此，该研究计划将为诸如失用症等影响发音水平语言产生的障碍提供有价值的见解，并将有助于更好地理解用于语音识别和合成目的的韵律，这对那些患有沟通障碍的人也很重要。
