Abstract:One of many skills required to engage properly in a conversation is to know the appropiate use of the rules of engagement. In order to engage properly in a conversation, a virtual human or robot should, for instance, be able to know when it is being addressed or when the speaker is about to hand over the turn. The paper presents a multimodal approach to end-of-speaker-turn prediction using sequential probabilistic models (Conditional Random Fields) to learn a model from observations of real-life multi-party meetings. Although the results are not as good as expected, we provide insight into which modalities are important when taking a multimodal approach to the problem based on literature and our own results.
