Child's voice silenced during Teams video call

Hello,

Members of my family use Microsoft Teams to have group videocalls. My niece, who is a few years old, will often participate along with her parent. She has a high-pitched voice characteristic of her age group. Sometimes, when she speaks, her sound does not come across at all, as if her mic were silenced (but it is not silenced). Sometimes we can hear her fine, and we can always hear her parent and other members of that household fine. I wonder if Teams is identifying her voice as "noise" to be suppressed, but that is only my guess. This has been happening for at least several months, maybe for the whole year we've been using Teams. Is there something that I can do as the meeting host or something that can be done by my sibling (the parent) on their end? We love hearing from my niece during our get-togethers.

Thank you!

    This can happen when Teams audio processing treats a nearby voice as unwanted audio. In voice isolation, if someone nearby is detected while another person is using the device, Teams can filter that audio unless voice isolation is turned off.

    What to try on the parent’s device:

    1. Check whether voice isolation is on during the call.
      • If Teams shows that someone nearby is detected, select Turn off voice isolation so both the parent and child can be heard.
    2. If voice isolation is being used, watch the meeting indicator.
      • Teams can show when voice isolation is active and filtering out unwanted audio, or when someone nearby is detected.
    3. If the problem continues, try basic audio troubleshooting on that device:
      • Make sure the mic is not muted in the meeting controls.
      • Check whether the microphone itself has a physical mute switch.
      • In the device or browser privacy settings, make sure Teams is allowed to access the microphone.
      • Restart Teams.
      • Check Teams for updates.
      • Reconnect the microphone or try a different microphone.
      • If a voice profile is being used, delete and recreate the voice profile.

    What the meeting host can do:

    • There is no host-side setting in the provided guidance to force Teams to stop filtering one participant’s nearby voice.
    • The effective change is on the parent’s device: turn off voice isolation when the child is speaking from the same device or same room.

    If the child and parent are sharing one device, turning off voice isolation is the most directly relevant step.

    There is no "Voice isolation" option available in Teams Free application, but there is "Noise suppression" option available in Settings -> Devices. Ask you sibling to turn this option off. However, a similar option might also be available in Windows Audio settings, but this depends on the audio driver used for the Microphone.
