This is a very glaring issue and needs to not be allowed/corrected. Very annoying when you hear enemy using the wrong voice near you and you assume it's a teammate. When you hear voice like this it's part of identifying FOF and it's very frustrating to hear what you thought was a teammate behind you only to get shot by them a second later. Or vice versa. Your teammate gets shot and has the wrong voice and you turn around only to see your teammate behind you.
