I think that a wav sound would be much more immersive. What do you call those? Taunts, or something like that?
Well, I know that we already have vox. Sometimes, especially when I am able to fly, I cannot use my vox because it would interfere with others in the room (sleep, watching tv, reading, etc). So, a couple of button activated range vox calls:

"I have blood on my windscreen"......"That's gonna leave a mark"........... "flight lead, I am headed for home"........"I've got nothing left but empty belts, if I could I'd throw those at 'em too"......
Also, an automatic sound file could play over range when you received damage / pilot wound: "I'm dumping fuel"............ "Sarge keeps putting parts on this crate, they keep knockin' em off"........... "I'm hit, I wasn't supposed to be the target today"........
