I’ve been able to change the voice for atc, but how do I change the voice I hear for me (the pilot), running IF 18.1?
Go into your in app Settings -> Live ->Pilot Voice.
You can select from Aaron, Alex, Catherine, Daniel, Gordon, Karen, Martha, Moira, Nicky, Samantha and Tessa. You can also adjust the pitch of the voice.
Edit: Thanks to an excellent support cast. The above voices are available on iOS not Android. Sincere apologies if this caused any confusion.
For iOS users Samantha is literally default siri
