Importance of Prosody for Dialogue Act Recognition

Importance of Prosody for Dialogue Act Recognition

This paper deals with automatic Dialogue Acts (DAs) recognition in French and in Czech. In this work, only prosodic features are considered. The utterances are recognized according to three types of dialogue acts: statements, yes/no questions and other questions, mainly wh-questions. We show that it is not possible to recognize all utterances only with basic prosodic features (F0 and energy) in real conditions with a good accuracy.
