This study investigated the effects of individual autistic traits on productive prosody of Japanese utterance-final particles (UFPs) as social markers expressing the speaker’s moods, based on previous studies reporting atypical patterns in speech prosody by people with autism spectrum disorders (ASDs). Analysis of the prosodic features of UFPs obtained from a role-play task by typically developed native Japanese speakers revealed that individual speakers’ autistic traits significantly affected the duration of the UFPs, but intensity and pitch did not show any significant effects. Speakers with higher autistic traits tended to utter UFPs in shorter times, in comparison with those with lower autistic traits. This study provides evidence that the atypical prosody associated with autistic traits may be reflected in the duration of mood morphemes.
