"CBS This Morning" correspondent Mo Rocca visited North Carolina recently to film a report on homogenizing American accents. And no report on American accents is complete without a chat with N.C. State professor Walt Wolfram about the hoi toiders of Ocracoke. Wolfram, a William C. Friday Distinguished University Professor, has been studying dialects for almost than 50 years and has been at N.C. State for the past 20.

"Studying dialects in North Carolina is like dying and coming to dialect heaven," Wolfram told Rocca. "It's incredible. There's no state that has a richer tradition."

Video of Rocca's report is below and includes "CBS This Morning" host and North Carolina native Charlie Rose talking about this own accent.
