Syntax influences the accuracy of consonant production in language-disordered children

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.
