We’ve all been in meetings where the conversation competes with everything happening around it. A nearby conversation, room noise, or other voices can make it harder to stay focused on the person speaking. That can slow down the meeting, create confusion, and make the experience more tiring for everyone involved. That’s where voice isolation in Microsoft Teams can help.
Voice isolation is designed to reduce noise and separate your voice from other sounds and voices in Teams calls and meetings. In simple terms, it helps Teams recognize who you are trying to hear and filter out what does not belong in the conversation. Background noise affects meeting quality in by making the speaker harder to understand and distracting to listening participants.
How voice isolation works
Voice isolation uses a personalized deep voice quality enhancement AI model to separate a user’s voice from other sounds and voices in Teams calls and meetings. To use it, create a voice profile. The profile is only stored on the local device. Additionally, the voice profile is not used for anything else.
To learn more about how your users can set up a voice isolation profile, see Create your Microsoft Teams recognition profile. To learn about enrollment, see Overview of voice and face enrollment.
In Teams, go to Settings and select Recognition. Then select "Opt in" button. Once that is selected, then the Create button will appear.
You will be prompted to read a short paragraph of text. This voice recording is what will be used to train the model.
After this is fully setup you can export or delete your profile. There is also an option to keep your profile updated automatically. If you enable this Microsoft, on behalf of your organization, will collect and process your pitch, inflection, and speech patterns to build your unique voice profile.

How Voice Isolation looks once enabled
After you add your voice profile, indicators will tell you when and how voice isolation is working in your meeting or call.

Final takeaway
Teams voice isolation is a practical feature for improving meeting clarity. Microsoft describes it as a way to reduce noise and separate a user’s voice from other sounds and voices, helping meetings feel cleaner and easier to follow.
This can be especially useful in:
