Using Acoustic Clues to Distinguish Speech Repairs and Intonational Phrase Boundaries

Abstract:In spoken dialogue, hearers can make use of acoustic clues to understand what the speaker is saying. Previous work has shown their utility in signaling intonational phrase boundaries and prominence in professionally read speech (Wightman and Campbell, 1994). However, in spoken dialogue, intonational phrase boundaries and speech repairs seem to share acoustic as well as lexical clues. So it is necessary to resolve both issues at the same time. In this paper, we extend the existing approach to account for both intonational phrase boundaries and speech repairs in spontaneous speech. We also incorporate these clues into a statistical model, based on a part-of- speech tagger, that takes into account lexical clues.
