We propose a prototype for a system to verify the decision support of a group based on estimations of group status through utterance analysis.

Based on methods used in prior studies of group dynamics and utterance analysis, we measured the utterance characteristics of group members to infer group status; moreover, we aimed to enhance the overall condition of the group by providing appropriate reference information in a timely manner through a conversational agent system. The goal of this system was a more satisfying decision-making process.

We manufactured a prototype system to verify both the operations involved in the test case and the ability to infer group classification and status according to group dynamics.

Our proposed method was appropriate based on the prototype system. Future work will focus on optimizing the logic and system functions of group status estimation and the subsequent step of informing the group.
