Introduction: Narratives are enriched by taking the perspective of the protagonists, which can be expressed using reported speech. Nevertheless, the use of reported speech is unaddressed internationally among individuals with Down syndrome. Method: Narratives of 28 children and adolescents with Down syndrome were collected using a non-verbal picture book. Occurrence and forms of reported speech were analysed and compared to typically-developing children (TD; n = 33). Results: Participants from both populations use reported speech in their narratives with a comparable proportion. Nevertheless, differences appear concerning forms of direct speech with persons with Down syndrome using more free direct speech than TD-children. Discussion: The results suggest that children and adolescents are able to implement the use of reported speech regardless of their syntactic impairments. Concerning the occurring forms of direct speech, the results might point to cognitive impairments that manifest in limited consideration of the interlocutor's knowledge.
