ARTICULATORY TIMING--ORGANIZING SYLLABLES AND PHRASES

拟议研究计划的重点是了解如何 语言结构高于段的水平条件， 语音的时间实现。 具体来说，发音模式 音节和短语的韵律结构。 这 该计划将调查口语的时间协调和衔接 发音手势作为其音节和短语的功能 岗位 一系列实验，使用发音运动数据 描述了用磁力计系统收集的数据。 这些实验 分为三个方面：音节边缘的手势之间的时间 （声母vs.韵母）和音节核;等级的影响 短语结构对手势间时间的影响;以及 韵律结构引起音段交替，即，明显的 用一个片段替换另一个片段。 这些实验将 提供一个轮廓，其中发音协调之间的方式， 多个手势是由位置上下文塑造的， 希望能定义韵律结构的一般“特征”， 发音组织

The focus of the proposed research program is to understand how linguistic structure above the level of the segment conditions the temporal realization of speech. Specifically, the articulatory patterning of syllables and phrases--prosodic structure--is considered. This program will investigate the temporal coordination and cohesion of oral articulatory gestures as a function of their syllabic and phrasal positions. A series of experiments, using articulatory movement data collected with a magnetometer system, are described. These experiments fall into three areas: the timing between gestures in syllable margins (initial vs. Final) and in syllable nuclei; the influence of hierarchical phrasal structure on intergestural timing; and the manner in which prosodic structure induces segmental alternations, that is, apparent substitutions of one segment for another. These experiments will provide a profile of the way in which articulatory coordination among multiple gestures is shaped by positional contexts, ultimately with the hope of defining general "signatures" of prosodic structure on articulatory organization.
