To investigate the profile of stuttering within the Down syndrome population, we have collected videos of natural speech samples from 83 English-speaking people with Down syndrome from around the world. Transcription and disfluency analysis was conducted on 54 recorded samples from participants who were observed producing stutter-like disfluencies (SLDs) to examine the typical distribution of primary stuttering behaviors and other disfluencies (ODs), for people with Down syndrome who stutter. The linguistic profile of SLD occurrence was also examined, finding that a greater proportion of stutters occur on content over function words within an utterance. Clinical considerations and implications are explored.
