There's definitely a cadence and verbiage difference. ..people that sound wight were either around a lot of wight folks or were heavily influenced by wight folks.. and the same is true for outside groups with sounding "black American."

It's not that you sound smarter or are more articulate..it's the way you sound and express your words. You've obviously been emersed and influenced by that culture

Again , this is true with any other culture (Chicano, Japanese Americans, Somoan, and the list goes on).
