We have explored the usefulness of incorporat- ing speech and discourse features in an automatic speech summarization system applied to meeting recordings from the ICSI Meetings corpus. By an- alyzing speaker activity, turn-taking and discourse cues, we hypothesize that such a system can out- perform solely text-based methods inherited from the field of text summarization. The summariza- tion methods are described, two evaluation meth- ods are applied and compared, and the results clearly show that utilizing such features is advanta- geous and efficient. Even simple methods relying on discourse cues and speaker activity can outper- form text summarization approaches.
