RESEARCH PROGRAM ON DYNAMICS OF SPEECH ARTICULATION

这项研究致力于研究语音的运动组织。 语音声学与发音运动和潜在控制的关系 功能。实现该目的的技术包括声学分析， 纤维光学观察、透照、X射线观察和肌电图术 关节结构，尤指舌头、舌瓣口和喉部。正常 言语运动组织可以从两个方面进行研究。演讲可以被视为 生成语言信息的系统的输出，当语言信息由 传统上，在不同的分段和超分段环境中组装单元 定义为协同发音和补偿的研究。或者，演讲 可能被视为一种熟练的汽车行为，其组织由 系统在持续发音过程中对扰动的反应。平行化 正常研究我们将调查三个临床群体：口吃者，聋人， 以及语言失用症、不流利或布罗卡氏失语症患者。这些 后三组将从言语运动的角度进行研究 计划。

This study is devoted to the study of the motor organization of speech by relating speech acoustics to articulatory movements and the underlying control functions. The techniques to accomplish this object include acoustic analysis, fiberoptic viewing, transillumination, x-ray viewing and electromyography of the articulatory structures, especially the tongue, velar port, and larynx. Normal speech motor organization is to be studied in two ways. Speech may be viewed as the output of a system for generating linguistic messages as they are formed by assembling units in varying segmental and suprasegmental contexts, traditionally defined as studies of coarticulation and compensation. Alternatively, speech may be viewed as a skilled motor act, whose organization is revealed by the response of the system to perturbation during ongoing articulation. To parallel normal studies we will investigate three clinical groups; stutterers, the deaf, and those with apraxia of speech, or non-fluent or Broca's aphasia. These latter three groups will be studied from the point of view of speech motor planning.
