The present investigation was designed to examine the effects of phonetic context and linguistic complexity level on /s/ misarticulations in children. The subjects were normal children who misarticulated the /s/ phoneme interdentally in all positions of words. The stimuli were 48 sound-in-context initiative sequences which contained one /s/ phoneme embedded in a C1SC2 frame with all permutations of the phonemes /k,t,n,p/ in the C1 and C2 positions. The 48 sequences were composed of two basic linguistic complexity levels. The simple level consisted of the C1SC2 frame occurring in 16 noun phrases and in the more complex linguistic level seven-word sentences contained the C1SC2 frames in the subject-noun-phrase and object-noun-phrase positions. All presentations of complexity levels were counterbalanced over the three trials for a total of 144 /s/ productions for each child. Results demonstrated that certain phonemes were more facilitory for correct /s/ production than other phonemes. The analysis revealed no position effect. The mean percent correct /s/ productions over three trials did not differ significantly; however, the mean percent correct /s/ productions did vary significantly with linguistic complexity levels by position.
本研究旨在考察语音语境和语言复杂程度对儿童/s/音错误发音的影响。研究对象是在单词所有位置上都将/s/音发成齿间音的正常儿童。刺激材料是48个语境化语音起始序列，其中包含一个嵌入在C1SC2框架中的/s/音，C1和C2位置上是音素/k、t、n、p/的所有排列组合。这48个序列由两个基本的语言复杂程度级别组成。简单级别由出现在16个名词短语中的C1SC2框架组成，在更复杂的语言级别中，七个单词的句子在主语名词短语和宾语名词短语位置包含C1SC2框架。所有复杂程度级别的呈现都在三次试验中进行了平衡，每个儿童总共产生144个/s/音。结果表明，某些音素比其他音素更有助于正确发出/s/音。分析显示没有位置效应。三次试验中/s/音正确发音的平均百分比没有显著差异；然而，/s/音正确发音的平均百分比确实因位置的语言复杂程度而有显著差异。
