Voice isolation in Microsoft Teams calls and meetings

Applies To
Teams Microsoft Teams

Filter out background noise during Teams calls and meetings with voice isolation. Voice isolation uses AI to block surrounding noise so others can hear you clearly.

How it works

When you add a voice profile, Teams will know which sounds to keep (your voice) and which ones to filter out. Voice isolation also filters out sound from other speakers to prevent echoes. Voice isolation is powered by AI within Teams.

Add your voice profile

Add a voice profile to start using voice isolation in your meetings and calls. A voice profile takes about 30 seconds to make and can be deleted anytime. For more information, visit Create your Microsoft Teams recognition profile.

To set up your voice profile:

  1. Select Settings and more  > Settings in Teams.
  2. Select Recognition Start transcription button .
  3. Select Start voice capture.
  4. After opting in, Teams will begin generating your voice profile at the next eligible meeting.
  5. After Teams finishes generating your voice profile, you will see a Voice profile complete indicator underneath the Voice recognition section.

If you do not want to wait for Teams to generate this voice profile, you can manually enroll your voice. This functionality is also available if you want to update your voice profile after it’s been generated.

  1. To manually enroll, select Create or Update.

  2. You’ll be asked to read a passage into your microphone. Make sure your mic is selected from the device dropdown menu.

  3. Select Start voice capture and read the text aloud.

    Tip

    Record your voice profile in a quiet location, using a high-quality microphone for best results.

  4. Select End voice capture when you're done.

  5. You can start face recognition setup right after you're done creating your voice profile, or select Close to do this a different day.

    Note

    If you don't see Recognition Start transcription button in your settings, contact your IT admin.

Turn off voice isolation

Voice isolation will be active in your calls and meetings after you add your voice profile.  

To turn off voice isolation in a Teams meeting:

  1. Select the dropdown arrow next to Mic Mute button in your meeting controls.
  2. You can either switch to Background noise only or turn off Noise suppression using the toggle.

You can also access these settings by selecting the dropdown arrow next to Mic Mute button  and selecting More audio settings.

How it looks

After you add your voice profile, indicators will tell you when and how voice isolation is working in your meeting or call.
