Voice isolation in Microsoft Teams calls and meetings

Gäller för

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.

To add your voice profile:

Select Settings and more > Settings in Teams.
Select Recognition .
Select Create voice profile.

Note

If you don't see Recognition in your settings, contact your IT admin.
Choose your microphone from the dropdown menu.
Select Start voice capture and read the provided text.
When you finish reading, select Stop voice capture.
Select Close.

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:

Select the dropdown arrow next to Mic in your meeting controls.
Turn off the Noise suppression toggle.

You can also access these settings by selecting the dropdown arrow next to Mic 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.

Indicator	What it means
	Voice isolation is turned on and active.
	You entered the meeting with your mic muted.
	Only your name is displayed. Unwanted audio isn't detected and voice isolation is active.
	Voice isolation is active and filtering out unwanted audio.
	Someone nearby is detected (e.g., you and a colleague are sharing your device for the meeting). If you want them to be heard, select Turn off voice isolation.

Troubleshooting

If you're having issues adding a voice profile:

Make sure you're in a relatively quiet environment.
Connect your microphone again or use a different one to improve your audio.
Restart Teams.
Check Teams for updates.
Delete and recreate your voice profile.
