Good question, those are all different accents we are pointing out this model does well with, but it also does well with White American accents that are usually represented well, not only the Black voices (including White southern voices).
We are calling out Southern American, and the regional African English (e.g. a person with a regional Nigerian (igbo) accent speaking english, or someone with a regional Kenya (Swahili) accent that is still speaking english). Those are all different but all represented well in this model.

Those were not a catch all for black americans.
