This is just something that's always bothered me in Elder Scrolls, I don't know what anyone else thinks about this but for me it just kinda irks me out.
I just kinda dislike when they use American accents for characters in Elder Scrolls games. For me, part of being immersed in a classical-medieval themed world is getting to hear characters that sound like they were from medieval europe, or the middle east, whichever part of Tamriel we're talking about here.
When I hear American accents in Elder Scrolls it just kinda suspends the immersion for me. Two characters in particular, for the dark brotherhood, Astrid and Nazir sound WAY too American for my taste. I think Astrid would've sounded way cooler if she had a smidgen more European in her accent, and Astrid had something like an Afro-Arabic accent. To me, that's just more exotic and feels more different to what I'm accustomed to living in America. I mean I hear American accents every day and it's just so plain and boring to me, when I want medieval fantasy I want it to sound as distinct from Modern American accents as possible while still using the English language, for me that's what does the trick. Just Eurasian accents just help me feel more escapism from day to day life that I expect routinely.
I was so relieved when Skyrim came out, and I heard many of the Nords had a Nordic-ish accent as opposed to what we saw in the E3 demo with characters like Alvor's original voice.
The only race in Elder Scrolls where american accents are somewhat appropriate for me are the Imperials and people living in the province of Cyrodiil. But that's just because we have a lot of movies in American film for Rome where all the characters speak American English going back to films from the 40's, the image of Romans with American accents is so ingrained in American pop culture it has become somewhat appropriate.
That being said, I still prefer for Imperials to have an accent that is at least somewhat Latin in nature. Somewhere between what we see in American movies and in the middle towards Ecclesiastical Latin spoken in Catholic Mass but with a deeper, more powerful voice I think would be absolutely perfect for an Imperial soldier.
Idk, just my thoughts.
