Intonational variation is widely regarded as a source of information about the topic structure of spoken discourse. However, many factors other than topic can influence this variation. We compared two models of intonation in terms of their ability to account for these other sources of variation. In dealing with this variation, the models paint different pictures of the intonational correlates of topic.
