Sesame released TurnBench, an open-source benchmark for evaluating turn-taking dynamics in spoken dialogue. The benchmark includes a public leaderboard, interactive conversation viewer, and self-serve scoring on the dev set. It was developed in partnership with Carnegie Mellon University, Mundo AI, Oto, and researchers from several other institutions.
