Windows host process rundll32 using microphone

I've read that these are just Windows files, I'm curious on why they are using my mic though. When I trace them, they bring me to syswow64 and system32, so there is no way its malware as other people claim. I've ran multiple scans with Windows Defender and Malwarebytes and they all came green. Do my apps cause this? The only other apps I think can use these services are Cortana, Alexa, and MSI's Dragon Center (MSI motherboard)

Windows 10 2004

run32dll.exe is a way for other apps to use shared DLL files so there's only one copy of it in memory rather than dozens of them.

rundll is just a way that other apps can get access to dll procedures, so you need to know what process/service/driver that have done the call via rundll to know anything about what goes on.
