A mysterious voice is haunting American Airlines’ in-flight announcements
I'm late to the game BUT just in case someone sees this:  Not so long ago they found that deep fake voices don't emulate the shape of the mouth and throat very well, and therefore it's easy to tell if a clip is a deep fake, or real.<p>They should be able to run these sounds through the same software to see if it properly emulates a throat and mouth or not.
