I would also rather play muted (dumb?) character than listen curent voices on my Dwarf.

I dont mean to say they are bad ... just that they arent Dwarf.
Yes, I’ve said it before but will take any excuse to say it again, there is a definite gap in the voice sets so far available.
English voice 4 is a posh/cultured female-sounding voice, voice 2 is more “common” version (as a commoner myself, I say that in a totally non-derogatory sense). One or the other of them has fitted almost every female character I’ve wanted to play, but not my dwarf barbarian for whom I really wanted a deeper, gruffer voice, that would also be suitable for, eg, various other warriors and (hopefully) half-orcs.
Voice 1 is a posh/cultured male-sounding voice, and voice 3 is … a slightly deeper posh/cultured male-sounding voice. I don’t know why we don’t just have analogues to voices 2 and 4. And again we’re missing a deeper, gruffer voice.
Given I do want voiced protagonists, it would be unfair of me to also want lots of custom voice sets. But I think that six in total, if carefully chosen and clearly distinct, could cover almost every character I might want to create.
