Well, the the developers never made "Iberian" voices" you never hear the Iberians saying "Iberia is mother to us all" instead they say "Gaul is mother to us all" while the germans, gauls and britons all say their respective lands in the voices. I think its because the Iberians were a late DLC they didn't gave the energy to give them a unique voice, paid developers (companies) are so lazy, modders do better jobs. with less tools

Originally yes, in the game most Iberian soldiers had voices that were of African units, well northern African Units. All have been changed to Iberian voices.

What you mean the audio had been changed ? Do they speak like africans and Celts?

Mercs weren't this advance in this alternate time.

what about there mercs and aux counterparts?
