Prosodic features of children's utterances were compared across assertive directive tasks, in order to determine how these acoustical properties of speech are used for communication. Methodological difficulties inherent in many previous investigations were averted by using a procedure that ensured that prosody was judged independently of communicative purpose. Four children aged 1;11 were audiotaped while in contexts designed to elicit assertive or directive utterances to an adult. The children's utterances were analysed for intensity and duration as well as beginning, end, peak, and low frequencies, frequency range, and contour changes. Results showed that in the directive context intensity was increased overall. Increased end point frequency and a trend for increased overall peak frequency were also noted, although the way in which the latter features were used varied with individual children. Beginning frequency and frequency range also showed significant task by child interactions, but no main effect for task. These findings indicate that children at this age use prosodic elements of speech differentially across communicative contexts and code their intentions with multiple features. Differences between children may reflect individual differences or developmental effects.
