ABSTRACT
This study focuses on the prosodic aspect of Autism Spectrum Disorder (ASD) associated with characteristics of the disorder. The subjects are male ASD speakers aged 9 to 12 years old. The data was collected using reading and imitation techniques and subsequently processed using the PRAAT program. The results show that there are variations in duration among ASD speakers. The duration from the reading technique tended to be longer in comparison to the imitation technique, and the size of the differences varied greatly. Both techniques, reading and imitation, produced longer durations for interrogative sentences than declarative sentences. Interrogative sentences produced by ASD speakers tended to be longer on the final syllable of the object constituent. This indicates that ASD speakers have difficulties in detecting the end of a speech boundary. Meanwhile, the short duration produced by ASD speakers on a subject constituent indicates that they have a tendency to fail to understand the function of a subject constituent in a sentence.
