The sound of thoughtspeak, and skin-color in fiction books
I'm reading Will Do Magic For Small Change by Andrea Hairston, which features almost exclusively black characters so far, some of whom (to some extent) use AAVE, and some who were described as having some kind of a southern drawl.
I'm used to reading books by white authors with white (or unspecified but probably white) characters. Characters are white in my mind unless a book says otherwise. And in my mind, their voices are also just like mine (I don't personify feminine voices either).
The thoughtspeak in my head (the imagined sound I hear as I read words, or especially as I read what a character is saying) almost never has any character to it. It's pretty flat, and has a stereotypical white tone to it, if anything.
Thing is - I can imagine black characters, see them in my head, and depict the different descriptions of their skin color ("So brown he's almost black" I read in another book recently). White characters never have their skin-colors described by white authors I've read, though we do range from basically paper-white to peachish to darkly-tanned italian-like.
But ... I don't hear different thoughtspeak. I think I could. But I would need to practice. I think it would be neat. And I think being able to hear different accents and tones could help me do impressions if I wanted to, too. I've never been good at impressions. (There's an irish character in Overwatch that I'd like to impersonate)
