Speech disfluencies in children with Down Syndrome

Approximately 30 percent of children with DS between 3 and 13 years of age in this study stutter, which is much higher than the prevalence in normally developing children. Moreover, this study showed that the speech of children with DS has a different distribution of types of disfluencies than the speech of normally developing children. Although different cluttering-like characteristics were found in the speech of young children with DS, none of them could be identified as cluttering or cluttering-stuttering.
