The authors present a method for generating conversations between human-like agents and this will be done by proposing specific parameters for inter-agent messages with an approximation of virtual sound propagation. We will then be able to simulate appropriate human-like behaviours automatically. For instance, we demonstrate how to create proper reactions for agents that are not able to understand, but only to hear the sentences. Finally, we develop the notion of conversation privacy and inter-agent cooperation, as all our agents share the same virtual space
