The liquid, fricative, and affricate sounds in the phonological system of a single misarticulating child were the focus of converging analyses. These analyses included structured measures of perceptual and productive skills, language sampling, and acoustic analysis of seemingly homophonous forms. The results of perceptual and productive tasks indicated that the child's perception of certain sounds was superior to his productions, but for other sounds, productive skill was superior to perceptual performance. This child's errors of production could be attributed to nonadultlike underlying representations. A two-lexicon model of underlying representation best accounted for the data. The findings led to inferences about the child's underlying perceptual and articulatory knowledge of fricative, affricate, and liquid sounds.
对一名发音错误儿童语音系统中的液体音、摩擦音和塞擦音进行了综合分析。这些分析包括感知和生成技能的结构化测量、语言抽样以及对看似同音异形词形式的声学分析。感知和生成任务的结果表明，该儿童对某些声音的感知优于其发音，但对于其他声音，生成技能优于感知表现。这个孩子的发音错误可归因于非成人式的底层表征。一个关于底层表征的双词库模型最能解释这些数据。这些发现得出了关于该儿童对摩擦音、塞擦音和液体音的潜在感知和发音知识的推论。
