ARTICULATORY TIMING--ORGANIZING SYLLABLES AND PHRASES

拟议的研究计划的重点是了解如何 语段层次以上的语言结构决定了 语音的时间实现。具体地说，发音图案 音节和短语--韵律结构--被考虑。这 项目将调查口语的时间协调性和衔接能力 发音手势与其音节和短语的关系 各就各位。一系列实验，使用关节运动数据 描述了用磁强计系统采集的数据。这些实验 分为三个方面：音节边缘手势之间的时序 (声母与韵母)和在音节核心中；等级的影响 关于胎间计时的短语结构；以及 韵律结构引起节段性变化，即明显的节段性变化 用一段替换另一段。这些实验将 提供一个简档，说明如何在 多个手势由位置上下文决定，最终由 希望将韵律结构的一般“特征”定义在 口齿清晰的组织。

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.
