PHYSIOLOGICAL AND ACOUSTICAL STUDIES OF SPEECH

描述：本研究的一个目标是开发和完善 说话者对离散的语言表示进行编码的过程 发音结构的运动模式， 然后转换成声音的模式。 这些模型将描述 这些模式的变化，从一些发言者和推断范围 发音模式的声音。 重点将放在 各种语音环境中辅音产生的模型。 第二个目标是开发程序， 由具有某些言语障碍的说话者产生的言语， 根据发音过程来解释这些测量结果。 再次 待研究的语音材料将主要包括辅音， 以及喉声源的测量。 措施将 导出的无序的偏差的定量规范 发音模式与正常说话者的发音模式不同 无序 待研究的群体包括患有运动性语言障碍的个体， 严重重听的演讲者，以及某些 喉部疾病 基于无创声学的偏离正常范围的测量 预期测量可应用于语音诊断 疾病，用于规划治疗疾病的程序， 并对干预的结果进行定量评估。

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.
