Dialogue Act Compression via Pitch Contour Preservation

Gabriel Murray, Steve Renals

University of Edinburgh, UK

This paper explores the usefulness of prosody in automatically compressing dialogue acts from meeting speech. Specifically, this work attempts to compress utterances by preserving the pitch contour of the original whole utterance. Two methods of doing this are described in detail and are evaluated subjectively using human annotators and objectively using edit distance with a human-authored gold-standard. Both metrics show that such a prosodic approach is much better than the random baseline approach and significantly better than a simple text compression method.
