I think it’s less true now than it once was, but I remembering hearing somewhere that pre-recorded messages on trains/subways/in stations tend to use feminine voices for information, and masculine voices for instructions.
There are definitely still times on the London Underground where you’ll hear announcements that switch in the middle, and that does usually seem to be the pattern.
(I realise this doesn’t really apply to GPSes, but your comment is what reminded me, so. 😅)
