title: Articulatory inconsistencies in the speech of normal children.
abstract: The spontaneous speech of three children about three years old was recorded and transcribed into CnV syllabic units. Cn represents any number of consonants preceding a vowel and is not lexically constrained. Inconsistent production of /s/ and /z/ was found to be related to motor sequencing constraints independent of word boundaries. The results support a model of speech physiology as well as theoretical formulations of child speech production within an adult phonological system.
