This research investigates verbal and non-verbal cues that support dialogue coordination and explores their application to human-computer interaction. Studies examined differences in speech directed to computers versus humans, finding louder speech for computer-directed utterances, and identified gaze as a key—but error-prone—cue for addressee perception. Analysis of disfluencies revealed that “um” is listener-oriented, while “uh” is speaker-oriented. Further, inter-turn gap length influenced response timing and disfluency likelihood. Finally, reinforcement learning simulations demonstrated that incorporating coordination cues can improve SDS dialogue policies. 000000715 540__ $$fCC BY 000000715 542__ $$fIn copyright - single owner 000000715 650__ $$aLanguage Development Disorders$$021312 000000715 650__ $$aAutistic Disorder$$015231 000000715 650__ $$aLanguage Disorders$$021313 000000715 650__ $$aUser-Computer Interface$$027668 000000715 650__ $$aComputer Simulation$$016989 000000715 650__ $$aCommunication$$016935 000000715 650__ $$aAutism Spectrum Disorder$$011199 000000715 6531_ $$ahuman-computer interaction 000000715 6531_ $$aspoken dialogue systems 000000715 691__ $$aSchool of Medicine$$041369 000000715 692__ $$aCenter for Spoken Language Understanding$$041388 000000715 7001_ $$aLunsford, Rebecca$$uOregon Health and Science University$$041354 000000715 7201_ $$aHeeman, Peter$$uOregon Health and Science University$$041354$$7Personal$$eAdvisor 000000715 8564_ $$956a9dc3a-7eb8-4806-9d00-0a9e84bb4418$$s1369034$$uhttps://digitalcollections.ohsu.edu/record/715/files/718_etd.pdf$$ePublic$$2107fab4241cec5ba342bd2c6ee57db69$$31 000000715 905__ $$a/rest/prod/9z/90/2z/88/9z902z88f 000000715 909CO $$ooai:digitalcollections.ohsu.edu:715$$pstudent-work 000000715 956__ $$aGet Accessible Copy$$uhttps://ohsu.libwizard.com/f/requestaccessibledocument 000000715 980__ $$aTheses and Dissertations
