Unknown Speaker as Call Audio Option

This speaker randomly appeared in my call options today. I've never owned any Apple speaker, let alone connected to one. It's not in my BlueTooth options, and it stays there when I turn off BlueTooth. Updating to the latest version did not fix this. I tried installing Home as recommended in a previous forum post, but the app won't load at all. It just sits at "Loading Accessories and Scenes". That said, I've never used the app nor accepted a request to be in any home. I also reset my network settings, as recommended, and that didn't remove it either. It disappears when I turn wifi off, but I obviously need wifi. When I call someone via Discord, the speaker doesn't appear despite Discord utilizing Apple's UI for calls.
