| Outline of Final Research Achievements |
This research focuses on modeling the explanation-performance of participants in group conversation. We present a multimodal analysis of explanation performance in group conversation as evaluated by external observers. A new multimodal data corpus, including the performance score of participants, is collected through group storytelling task. We extract multimodal features regarding explanators and listener from a manual description of spoken dialog and from various nonverbal patterns, including speaking turn, utterance prosody, head gesture, hand gesture, and head direction of each participant. We also extract multimodal co-occurrence features, such as utterance with head gestures. In the experiment, we modeled the relationship between the performance indices and the features using machine learning techniques. Experimental results show that the highest accuracy is 82% for the total explanation performance obtained with a combination of these features in a binary classification task.
