Vocal exchanges between individuals are often coordinated in a temporally precise manner: one party is vocalizing while the other one is listening until the performance roles are switched. This vocal turn-taking behavior is widespread across the animal kingdom and thus provides an opportunity to study the neural circuit mechanisms from a comparative perspective. Although the physical prerequisites of the vocal tracts across animals can be different, the behavioral outcome of turn-taking is often similar with respect to vocal response timing and context-dependent adaptation. Here we review behavioral strategies of vocal turn-taking in diverse animals. Further, we highlight recent advances in studying the neural circuit mechanisms underlying vocal production and perception.
