During the last debate....?

between Obama and Clinton, Obama kept prouncing "Taliban" like "tally-bon." I'm watching a tv show on it now. Native Afghan speakers are pronouncing it, "tail-eh-bon" and the American announcer is pronouncing it, "tal-eh-ban," so who is right? I know obama studied the qu'ran in arabic. So what is the correct pronounciation? Does he know because he studied the qu'ran?
