Ah this is my area, I'm a linguist.

Your question is very general, and whichever way I take it, the state of the field and research is such that we're not going to get many real answers any time soon, it's all pozzed.

Vocal chord differences? Nah that's going to be bollocks unless we're talking other species of human, or birds. IQ? Yeah it's going to impact you. But I actually think it's mostly a series of gauntlets, we need to consider neglect and residual elements of their pidgin-creole english, and then a culture which pulls down those who act 'white' in the cases that you're talking about.

There are certain 'critical periods', a baby has to meet certain milestones if they're to be able to continue to develop language normally, once you get past these ages if you haven't learnt certain language skills, you're fucked. Quite fucked at 3, and institutionalisation levels of fucked if you've still not developed them at 5 or 6 or so.

The wealthier and white parents talk with their kids, they read to them, they stimulate that learning. Look into the '30 million word gap' which they've desperately tried to discredit and poo-poo, as though it still doesn't show a massive difference with either race or wealth, or a combination (even if it can't parse exactly which or if that number is exaggerated, the difference is still there).

With less stimulation, you're going to get less kids meeting those particular milestones. The low IQ poor and/or black kids who were going to struggle to meet those milestones even if they had a lot of stimulation are now going to not hit them, and essentially have an induced language-learning disability their whole lives.

So there's an interplay, anyone of low IQ who might have been fine in a healthier culture is now in serious trouble.

Now they've made it past that gauntlet let's say, they are now being taught a different dialect in the home and in their school, and then all their peers socially discourage learning or speaking right. It's a fucked situation.
