Regional dialects can sound as different as foreign languages. Listener Ryan Willis of Florissant, Missouri wrote to ask how far apart people need to live in order to have different accents. Well, University of Pennsylvania linguist Bill Labov says it’s not a matter of distance.

But, contrary to popular belief, radio and television has very little influence on how we speak. If you have a science question, call us at 1-800-whyisit.
