Abstract: The present disclosure discloses a noise reduction method and apparatus based on in-vehicle sound zones and a medium. The method includes: determining, based on voice signals obtained by sound zones, a target sound zone to which a voice signal waking up a vehicle-mounted terminal belongs, in which each sound zone has a corresponding noise reduction module; and sending a noise reduction termination instruction to noise reduction modules of sound zones other than the target sound zone, in which the noise reduction termination instruction is configured to instruct the noise reduction modules of the sound zones other than the target sound zone to terminate noise reduction algorithms in a process of performing voice interaction for the target sound zone.
