Disfluency in Spontaneous Speech (DiSS'01)
August 29-31, 2001
Many factors conspire to cause speakers to produce hesitations and self-repairs in dialogue. It has been noted that disfluency rates vary between corpora, with different overall dialogue tasks and with different modalities (e.g. humancomputer vs. human-human) and between speakers, where they play different roles within a given dialogue.
In this paper, we attempt to account for some of these results by examining the interaction between rates of different types of disfluency and types of utterance (dialogue moves) within one corpus of human-human task oriented dialogues.
We find both that overall disfluency rate varies by dialogue move type, with moves which require more planning producing more disfluency, and that the distribution of disfluency types varies between move types, most notably with complex and negative responses to questions producing more filled pauses than positive replies and other moves.
This work helps us to understand how dialogue structure can account for differences in disfluency rates between and within speech corpora and has implications for research in speech production and perception, discourse studies, dialogue management and automatic speech recognition.
