This article presents a continuous and emergent model for the speaking turns coordination of user-agent dyads. The peculiarity of this model resides in its ability to manage incrementally a large number of situations observed in human spoken interactions, competitive overlaps or smooth transitions. We begin this paper by introducing our conceptual model then we introduce the implementation of our model. We finally evaluate our model by a wizard-of-oz experiment where users interact in real-time with the agent. The results of this evaluation shows that our model improves the agent’s ability to coordinate its speaking turns with the user. However, we also observe that users have difficulties to link the agent’s behavior to its intentions towards turn-taking management.
