Some variability in children’s productions of grammatical morphemes reflects contextual factors. Transcription has shown that 3rd person singular –s production is more robust utterance-finally compared to utterance-medially, and in simple versus complex codas. Acoustic analyses were used to examine further the influence of utterance position, and to examine whether word frequency affects morpheme production. The speech of 14 children (mean age = 2;3) was obtained using an elicited-production task. Results replicated the positional effect, but showed that morphemes were equally produced in low versus high frequency verbs, which suggests that contextual and lexical factors contribute differentially to morphological development.
