Coupled but Late: Turn-Taking Between Full-Duplex Speech Models in Unscripted Dialogue

Full-duplex speech models are trained to converse with a person, but they are increasingly made to converse with each other, in self-play data generation, agent societies, and model-based evaluation.

Key points

  • In that loop no human absorbs a timing error: each model's turn-taking is the other's input.
  • We ask what timing the loop settles into.
  • Two PersonaPlex-7B instances exchange audio tokens on a shared clock in unscripted conversation, and one floor-transfer rule is applied to them and to Switchboard.
  • Their timing is coupled: re-pairing speakers across conversations destroys it.
