I also want more type of voice, at least one that sounds evil or savage
Good point! Speaking for the English language voices, I think we do need a gruffer, deeper female voice and the two male voices are way too similar. I reckon you could get rid of one of those and replace it with a less posh version, corresponding to (female) voice 2 and then also add a gruffer, deeper one suitable for your stereotypical dwarves, half-orcs (hopefully!) and burly warrior types. I think there may actually be some additional player character voices at least partly recorded and unlocked in mods, though haven’t experimented with mods much yet.
Even more variety could be still better, but I live in hope of a fully voiced custom character and the more different voices there are, the less likely that would be possible.
