Abstract
This study focuses on the development of two temporal aspects of speech production, articulation rate and pausing, in children aged 9 to 14 years. Both measures were examined in spontaneous speech produced in interaction with a friend of the same age range and gender while completing a collaborative picture task. To investigate the use of articulation rate and pausing as clear speech strategies, two conditions were used that differed in the ease of communication between the two talkers. Articulation rate was higher in adults than in child groups, in male than female speakers, and was used as a clear speech strategy by all age groups. Pause frequency was variable within groups, but there was greater evidence of an increase in pause frequency as a clear strategy in adults than child groups, with no gender effect found for this measure. Overall, this study provides evidence for ongoing developments in certain aspects of speech production until adulthood.
