Voice isolation reduces noise and uses the personalized deep voice quality enhancement artificial intelligence (AI) model to separate the user's voice from other sounds and voices in Microsoft Teams calls and meetings. As an admin, you can control whether your users can use voice isolation in calls and meetings.

The voice isolation feature relies on the voice profile, stored on the user's local device, to remove any sounds or voices during a call or meeting that don't match the profile. Your users' voice profiles are only used for the reason they gave their permission for; Microsoft doesn't use their voice profiles for anything else. To use the voice isolation feature, your users must have a voice profile. To learn about how your users can set up a voice isolation profile, see Use Microsoft Teams Intelligent Speakers to identify in-room participants in a meeting transcription.

To learn about enrollment, see Overview of voice and face enrollment.

To learn more about voice isolation troubleshooting, setup, and the experience for your users, see Voice isolation in Microsoft Teams calls and meetings.
