I can see why someone would think the character's racist- and I do find the oddly exaggerated speech patterns annoying and unnecessary.
On the other hand, it's not like every black character in the game speaks like that (in fact, I'm pretty sure she's the only one), and she is from the slums of Detroit and is working as a garbage collector, so it's not like her speech patterns come from nothing.
