I know when I’ve heard it done it may be completely identical to a team mates voice. But when all your team mates are MALE, and hearing a female voice it doesnt strike me as a deterant. Just slightly odd.
But close to Eerie.
I think if they got the taunts correctly we might hear sounds along the lines of what was done in PRedators. Where it sounds like the player but in a much more whispering ghostly tone or deathly tone of voice.
OR it can be done in the Original or in Predator 2 where the voice is somewhere between the original voice and a machine voice (digitally manipulated). I think the machine voice is cooler but having both would be tremendously awesome and frightful at the same time.
