Atlas of North American English

The Atlas of North American English (formerly, the Phonological Atlas of North America) is an overview of the pronunciation patterns (accents) in all the major urbanized regional dialects of the English language spoken in the United States and Canada. It is the result of a large-scale survey by linguists William Labov, Sharon Ash, and Charles Boberg. It traces sound changes in progress in North America in the 1990s, and seeks to redefine dialect boundaries based on acoustic analysis of speech samples.

The Atlas of North American English received the Leonard Bloomfield Book Award at the 2008 meeting of the Linguistic Society of America.
