Battle troop voices

[benczeb90]

I just started playing as Rome (default campaign and script) and was wondering why the Saxons have Gallic in-battle voices. Pretty immersion breaking to hear 'Galla, aban!' from the Saxon invaders. Any way to customize battle culture sounds myself? thanks

EDIT: I'm using the soundmod. I can see now that there is no such thing - in this soundmod at least - as a separate Gallic/Celtic or Germanic battle voice, and they're merely generic Barbarian, and I guess they are all in Greek. :/
