Visualizing Spoken Discourse
- 217 Downloads
In this chapter we show that interruptions are important elements in the interactive character of discourse and in the resolution of issues of cognitive uncertainty and planning. By representing discourse graphically, we also show that interruptions are part of the local and global coherence that is brought about through the systematic phrase-to-phrase prosodic patterns of discourse. The specific pitch height of the interruption varies with the expression of emotion, signals of attention-getting, and signals of competitiveness. These prosodie forms are potentially usable in spoken dialogue systems to provide intelligent responding systems that are responsive to human motivations in dialogues.
