This lady can speak English in pretty much any accent imaginable.
Hearing her do this is an inspiration. When I read the chapters of Grizelda aloud, I try to “do the voices” for the characters. I know I’m not ready to do accents yet, but when you listen to Ms. Walker do 21 different accents all strung together, you get a sense of how it is people speak differently from each other. It’s got a lot to do with the vowels, and with pacing.
Her California sounds like a lot of people I knew going to high school in the Los Angeles basin. But by no means do we all talk like that there.
