INFERRING DISCOURSE STRUCTURE FROM SPEECH

The goal of the CLARITY project is to explore the use of discourse structure in the understanding of conversational speech. Within project CLARITY we aim to develop automatic classifiers for three levels of discourse structure in Spanish telephone conversations: speech acts, dialogue games, and discourse segments. This paper presents our first results and research plans in three areas: definition of discourse structure units and manual annotation of CALLHOME SPANISH, speech recognition, and automated segmentation and labeling of speech acts.
