PHYSIOLOGICAL AND ACOUSTICAL STUDIES OF SPEECH

描述：这项研究的目标之一是开发和完善模型 说话人对离散的语言表示进行编码的过程 将发音转化为发音结构的运动模式 然后变成声音的模式。这些模型将描述 一些说话者的这些模式的变化和推断范围 声学的发音模式。重点将放在 辅音在不同的语音环境中的产生模式。 第二个目标是开发程序，在 由有某些言语障碍的人所作的演讲 用发音过程来解释这些测量。又一次 要研究的语音材料将主要由辅音组成， 以及喉部声源的测量。措施将是 为定量描述无序的偏差而推导的 正常说话者音域中的发音模式。无序的人 要研究的人群包括运动性言语障碍患者， 严重重听的演讲者，以及有某些特定情况的人 喉部疾病。 基于非侵入性声学测量的正常范围偏差测量 测量有望在语音诊断中得到应用 障碍，用于规划治疗障碍的程序， 并对这一干预的结果进行量化评估。

DESCRIPTION: One goal of this research is to develop and refine models of the process whereby a speaker encodes a discrete linguistic representation of an utterance into patterns of movement of the articulatory structures and then into patterns of sound. The models will describe the ranges of variation of these patterns from a number of speakers and inferring ranges of articulatory patterns from the acoustics. Emphasis will be placed on models for consonant production in various phonetic environments. A second goal is to develop procedures for making acoustic measurements on the speech produced by speakers with certain speech disorders and for interpreting these measurements in terms of articulatory processes. Again the speech materials to be studied will consist primarily of consonants, together with measures of the laryngeal sound source. Measures will be derived for quantitative specification of the deviation of the disordered articulatory patterns from the ranges for normal speakers. The disordered populations to be studied include individuals with motor speech disorders, speakers who are severely hard of hearing, and individuals with certain laryngeal disorders. The measures of deviation from normal ranges based on noninvasive acoustic measurements are expected to have application for the diagnosis of speech disorders, for the planning of procedures for remediation of the disorders, and for quantitative evaluation of the outcome of this intervention.
