IT teams that want Microsoft Teams to catch a cloned voice or a face-swapped video in a meeting will need an outside vendor to do the catching. Microsoft plans to start rolling out support for certified third-party deepfake detectors in mid-November, and its admin notice spells out who does the work: “Synthetic media detection is performed by the third-party provider.”
