Pronunciation during Talk

I'm just wondering how well you guys can correctly pronunciate the words when reading articles or talking with people at a high speed. Well, I bet most of you must have known the authentic pronunciation and keep a standard way of your own to speak most words.

I kind of mixed up my tongue places when I was, with a high speed, reading words that start with t, d, n and th, though I totally sound pronouncing right to others. What worries me is I know this is not right, at least technically. I'm totally ok with these problems if at a medium speed.

May be it's because of me putting less focus on fast reading years before and now it ends up not so well.

pronounce correctly by putting your tongue incorrectly, I know this is weird. So tell me your opinons please?

A Question about Black English in USA Recently, I have been doing my homework about the American English and Accents. So I really want to get more information about the regular american's opinions to Black English. So if you're from America, please tell me how do you feel about the Black English and of course how well can you understand and communicate with some Black-English-speaking people. Giving some personal stories is really helpful, thanks.
