Complex disfluencies that involve the repetition or correction of words are frequent in conversational speech, with repetition disfluencies alone accounting for over 20% of disfluencies. These disfluencies generally do not lead to comprehension errors for human listeners. We propose that the frequent occurrence of parallel prosodic features in the reparandum (REP) and alteration (ALT) intervals of complex disfluencies may serve as strong perceptual cues that signal the disfluency to the listener. We report results from a transcription analysis of complex disfluencies that classifies disfluent regions on the basis of prosodic factors, and preliminary evidence from F0 analysis to support our finding of prosodic parallelism.
