Speech timing and pausing in children with specific language impairment.
Articulation rate, speaking rate, as well as the duration and location of pauses, were analysed in 10 children with specific language impairment (SLI) and a comparison group of seven younger children producing utterances of similar lengths. Children with SLI were significantly slower in articulation rate, but not speaking rate or pausing time, indicating a group difference attributable to longer syllable duration. The correlation between the duration of the pause preceding a child's speaking turn and the length of the subsequent child utterance was calculated as an indication of children's use of the pause for planning the utterance. The correlation was not significant in either group, and not significantly different between groups. An analysis of the position of pauses within speaking turns showed more syllables following than preceding the pause, with no significant group differences. Theoretical implications are discussed.
