The Xiaomi 15 offers a specialized noise reduction feature designed to reduce background noise, particularly in environments with children's voices. This can sometimes unintentionally filter out the sound of children’s voices during calls.
If you'd like to disable this feature and allow the children’s voices to be heard more clearly, follow these simple steps:
1. In the call interface, open [Call toolbox];
2. Locate and select the [Noise reduction] option;
3. Toggle it off to allow the children's voices to be heard by the other party.
