项目摘要

The proposed research aims to contribute to an elucidation of the relation between three levels of the process of human speech production: the discrete linguistic representation of an utterance in terms of words and speech segments within words; the acoustic pattern that results from the utterance; and the articulatory gestures that create the link between the linguistic and acoustic representations. Three aspects of this speech chain will be examined: (1) the acoustic and perceptual bases for some of the sounds that occur universally in language,, particularly certain features of vowels and of stop, fricative, and nasal consonants; (2) principles that govern the variability in production of speech sounds when the sounds occur in various contexts and are produced with different speech styles, particularly variability due to overlap of articulatory gstures and reduction of vowels in casual speech; and(3) the process by which children in the 3-7 year range acquire the words and sound contrasts in language. The developmental research with children will be based primarily on detailed acoustic analysis and interpretation of the children's utterances as their speech production strategies evolve from whole word units with minimal structure within words to sequences of smaller units that define the contrasts between words. This research will contribute to an understanding of the various stages involved in the production of an utterance, and will help to indicate the components within this process where deviations can occur, and the consequences of these deviations in speech production. It will also contribute to a description of the stages of normal speech development in children and an understanding of the basis for the progression through these stages.

拟议的研究旨在有助于阐明三个层次之间的关系，人类言语产生的过程：用词表达的话语的离散语言表示和言语段内的话;声学模式，从话语的结果;和发音这些手势在语言和声音表征之间建立了联系。这三个方面将检查语音链：（1）出现的一些声音的声学和感知基础普遍存在于语言中，特别是元音、塞音、摩擦音和鼻音的某些特征; (2)当声音出现在不同的语言环境中时，语境和产生不同的讲话风格，特别是变异性，由于重叠的发音（3）3-7岁儿童在日常言语中的动作和元音的减少; 音域习得语言中的词语和语音对比。儿童的发展研究将是主要基于详细的声学分析和对儿童话语的解释，产生策略从单词内具有最小结构的整个单词单元发展到定义单词之间对比的较小单位。这项研究将有助于了解话语产生的各个阶段，并将有助于指示其中的成分这个过程中可能发生的偏差，以及这些偏差在言语产生中的后果。它也将有助于描述儿童正常言语发展的阶段，理解通过这些阶段的进展的基础。
