Are newer civs’ voice files moddable?

Hi Modders
With the latest DLC, we now have 5 civs sharing the same voice set (Chinese, Jurchens, Shu, Wei, and Wu). I’ve been working on mods for a while, and I really want each civ to have its own unique identity. I believe that, whenever possible, every civilization should have its own distinct voice set.

The problem is: I can’t seem to find the voice file names (like .wem) for any civs added after the Dynasties of India DLC. Maybe they’re not moddable yet? Not sure.

Anyone happen to know more about this?
