Interactions between phonology and syntax are inspected in continuous speech samples from 30 speech-delayed children. Two types of interactions are examined: The co-occurrence of speech and language delay and the effects of phonological reduction on the realization of phonetically complex morphophonemes. Four possible patterns of association between the phonological and syntactic systems are outlined, and subjects are assigned to these patterns based on their phonological and syntactic performance. Results indicate that two-thirds of the subjects display evidence of overall syntactic delay, whereas half show some limitation in the use of phonetically complex morphophonemes, their performance in that area being below the level of their syntactic production. Implications of these findings for a theory of speech delay and for management programming are discussed.
