This paper presents a case study of a language-impaired child who invented a unique morphophonologic rule for signaling the distinction between English singular and plural nouns. Conventional linguistic-phonetic analysis indicated that the child was producing the distinction suprasegmentally rather than segmentally. Acoustic-phonetic analysis of matched singular-plural noun pairs was performed in order to determine quantitatively which suprasegmental acoustic cues he used to signal the distinction. Results of a multivariate analysis of variance revealed that singular and plural productions were significantly different from one another on various fundamental frequency, duration, and intensity parameters. This example of a child's linguistic creativity is offered as further evidence in support of a model of language acquisition that emphasizes the cognitive aspects underlying linguistic regularities in child language. Clinical implications are also discussed.
本文呈现了一个语言障碍儿童的案例研究，该儿童发明了一种独特的形态音位规则来表示英语单数和复数名词之间的区别。传统的语言语音分析表明，该儿童是通过超音段而非音段来体现这种区别的。为了定量确定他用来表示这种区别的超音段声学线索，对匹配的单数 - 复数名词对进行了声学语音分析。方差多变量分析结果显示，单数和复数发音在各种基频、时长和强度参数上存在显著差异。这个儿童语言创造力的例子被作为进一步的证据，以支持一种语言习得模型，该模型强调儿童语言中语言规律背后的认知方面。还讨论了临床意义。
