At this temp job of mine, I work in a small office room with two other people. One of them has a radio which she keeps tuned to a station which is a combination of R&B and a talk format. It bills itself as black people radio. One of the DJs actually said it that way- "You're listening to radio for black folk!"
In the afternoon, they have a talk host on who addresses "black issues."
I had to do some pretty extensive studying of vocal quality and tone when I was in college the first time around.
Based on his voice, I am 99.9% sure that this host is actually a white guy pretending to be black. It's not a matter of his vocabulary or language construction or accent; it's his voice itself.
I feel like I'm listening to some sort of weird vocal blackface thing.
