School-age children with specific language impairment produce more speech disfluencies than their peers.

PURPOSE To compare the occurrence of speech disfluencies during narrative production in children with specific language impairment (SLI) and their age-matched peers. METHODS The study included 60 children aged between 7 and 10 years, 40 with typical language development and 20 with SLI. For data collection, a series of 15 stories was used, each one represented by pictures composed of four scenes. Narratives were transcripted and the speech disfluencies presented on them were classified as stuttering-like disfluencies (part-word repetition, single-syllable word repetition, and dysrhythmic phonation - prolongations, blocks and broken words) or other disfluencies (interjection, revision/abandoned utterances, and multisyllable/phrase repetition). The disfluency categories were compared in each group and its occurrence was also compared between groups. RESULTS The occurrence of stuttering-like and other disfluencies did not differ among children with typical language development, whereas children with SLI produced other disfluencies. Between-group comparison showed that children with SLI produced more disfluencies of both types than their age-matched peers. CONCLUSION Children with SLI showed more speech disfluencies during narrative production than their age-matched peers, and the most common disfluencies used by them were not typical of people who stutter (interjection, revision/abandoned utterances, and multisyllable/phrase repetition).
