The American English Dialect Recordings collection, available online through the Library of Congress, contains 118 hours of recordings documenting North American English dialects. These include a variety of speech styles, including linguistic interviews, oral histories, conversations, and excerpts from public speeches. They were originally collected as part of Donna Christian's "A Survey and Collection of American English Dialect Recordings" funded by the Center for Applied Linguistics and the National Endowment for the Humanities.
The following table, prepared by Jaidan McLean and Charlie Farrington, includes all of the African American speech samples available in the American English Dialect Recordings collection. Because these recordings come from a variety of sources, genre indicates the type of recording that was made. A text file of this table is available here.
