This document summarizes a dissertation that studied the intonation patterns of sentences spoken in Indonesian by children with autism. The study found variations in the intonation patterns of declarative, interrogative, and imperative sentences. For declarative sentences, intonation patterns were influenced by sentence structure and final words. Interrogative sentences showed pressure through junctures or questioning intonation. Imperative sentences conveyed orders, prohibitions or requests through suffixes and intonation. The intonation patterns provided insight into how children with autism communicate and could help educators and parents support their language development.
