We all speak in different dialects. Today’s guest, John Baugh, provides history and context for those differences in the way we speak in the U.S., and explores their effects.

Baugh, president of the Linguistic Society of America, shares how dialect can be used to discriminate against people, which he refers to as linguistic profiling. Baugh explains how linguistic profiling can affect all facets of people's lives, from apartment leasing to legal proceedings. He also describes his experiences acting as an expert witness in court.
