My thinking also included Erenville, though slightly different.
If the two of them were childhood friends, or acquaintances as Erenville preferred, then I don't think it's a good idea to believe that the accents of those from Tural are intended to all be Latin/South American in nature. Erenville's clearly isn't. We've been given the information that Tural residents are very diverse in nature so chances are good any accents are intended to be related to race and not culture/nation.
If that is the case, then perhaps we should be wondering why Wuk doesn't sound more like the male Hrothgar that have had voice acting. I don't think we've had any voice acting for any of the Mamool Ja characters we've met so far - perhaps they'll be the ones represented by Latin/South American voice actors. I definitely agree that it's a missed opportunity for SE if they haven't included them.
Accent aside, did the voice acting feel a little off? Sure. I felt the same way about Lyse when she finally showed up at the end of HW and early in SB. It could be the voice actor trying to settle into a new character on fairly short notice. It could have been a decision of the voice director about how to portray a character that is relatively young and uncertain but trying to achieve great things and pretending confidence they really don't have yet.
Please remember that Wuk is effectively our new Lyse for Dawntrail. The WoL gets to be big brother/sister while we watch Wuk grow up, just as we did with Lyse.
Because we're dealing with a character that is uncertain, I was fine with the voice acting being a little off because the voice should and did reflect that uncertainty.
I disagree as someone who was born a woman and identifies as a woman. There was no moment in playing through the MSQ today that I thought of the character as anything but female when listening to the voice actor.
Seriously, trying to blame real life gender identity for any dissatisfaction is ridiculous. Men have been doing some female parts in acted entertainment for centuries. Women have been doing some male parts in acted entertainment for centuries.
It doesn't matter what gender identity a voice actor has. What matters is whether the voice acting helps to create the character the content director and producers want for their content. SE feels that this voice actor is the one they want for this character.
