It's not a big deal and I know there are other options for using flight crew voices but I'm curious if the default ones could be replaced with other recording files?  I haven't looked thru the folders yet (too busy flying ).

I had a look and can't see any obvious or simple way to.

I noticed lately that some of the passenge announcements are replayed double, they sound like there is an echo effect.

 

Anyone noticed that as well?

I have also noticed after landing the announcement of the cabin crew is carried out twice
