RESEARCH PROGRAM ON DYNAMICS OF SPEECH ARTICULATION

本研究致力于言语运动组织的研究， 将言语声学与发音运动及其底层控制联系起来 功能协调发展的 实现该目的的技术包括声学分析， 纤维光学观察、透照、X射线观察和肌电图检查 发音结构，特别是舌头，软腭端口和喉。 正常 言语运动组织可以从两个方面来研究。 演讲可以被视为 一种用于生成语言信息的系统的输出，所述语言信息是通过以下步骤形成的 在不同的音段和超音段语境中组装单位，传统上 定义为协同发音和补偿的研究。 另外，演讲 可以被视为一个熟练的运动行为，其组织是揭示了 在进行中的铰接期间系统对扰动的响应。 为并行 正常研究我们将调查三个临床组：口吃者，聋人， 和那些有语言失用症，或不流利或布洛卡失语症的人。 这些 后三组将从言语运动的角度进行研究 规划

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.
