PHYSIOLOGICAL AND ACOUSTICAL STUDIES OF SPEECH

这项拟议工作的目的是获得实验证据，证明 关于三个主题：(1) 语言，(2)片断的表面形式，当它们是 串联成更大的单元，以及(3)通过其进行处理的模型 会发生串联。除了实验研究外，我们还将 发展理论和模型，试图解释 人类感知、生产和认知系统的特征 在这三个地区都有。与主题(1)有关的研究将 包括收集关于声音的产生、声音形式和感知的数据 不同类别的语音，连同实验研究和 模拟人类发声和发声的一些基本特性 听觉感知系统。针对主题(2)的研究将 包括对出现在不同语言中的语音变异类型的研究 语言，特别是英语，以及这种变化如何与 语言因素与言语的生物力学因素和原则 马达控制。对演讲计划过程的研究(主题3)包括 协同发音规划的研究和声学-音标的确定 流利演讲中的规则及其顺序。其他实验将检验 言语错误(使用错误启发范式)和探索 演讲者的语段操纵能力(包括诸如 猪拉丁语)。结果将根据语音模型进行解释 计划。

The aim of the proposed work is to obtain experimental evidence that bears on three topics: (1) the features that characterize the segments of language, (2) the surface form that segments take when they are concatenated into larger units, and (3) models of the processing by which concatenation occurs. In addition to the experimental studies, we will develop theories and models that attempt to account for the influence of characteristics of the human perception, production and cognition systems on all three of these areas. Research concerned with topic (1) will involve collecting data on the production, acoustic form and perception of various classes of speech sounds, together with experimental studies and modelling of some basic properties of the human sound-generating and auditory perception systems. Research directed toward topic (2) will include studies of the types of phonetic variation that occur in various languages, particularly English, and how this variation interacts with linguistic factors and with biomechanical factors and principles of speech motor control. Research on the speech planning process (topic 3) includes studies of coarticulation planning, and determination of acoustic-phonetic rules and their ordering in fluent speech. Other experiments will examine speech errors (using an error-elicitation paradigm) and explore segment-manipulating abilities of speakers (involving "play-languages" like Pig Latin). Results will be interpreted in terms of models for speech planning.
