Nine children with restricted syntactic and phonological development repeated 20 target consonants embbedded in noun phrase, simple declarative, and passive structures to determine the influence of syntactic complexity on accuracy of consonant production. The children made significantly more errors in the sentence contexts than in the noun phrase context. This was found for both early-developing and late-developing consonants. However, the ratio of the number of distinctive feature modifications to the number of consonant errors showed that segmental errors were not produced as less exact approximations of the target consonants. Instead, the children simply made more errors of a predictable type, suggesting that the effect of syntax on accuracy of consonant production is quantitative rather than qualitative.
九名句法和语音发展受限的儿童重复了嵌入在名词短语、简单陈述句和被动结构中的20个目标辅音，以确定句法复杂性对辅音发音准确性的影响。与名词短语语境相比，儿童在句子语境中犯的错误明显更多。在早期发展的辅音和晚期发展的辅音中均发现了这一情况。然而，独特特征修改数量与辅音错误数量的比率表明，片段错误并非作为目标辅音不太准确的近似值而产生。相反，儿童只是犯了更多可预测类型的错误，这表明句法对辅音发音准确性的影响是数量上的而非质量上的。
