Dialectological map of English in the U.S. and Canada
The Atlas of North American English: Phonetics, Phonology and Sound Change is a 2006 book that presents an overview of the pronunciation patterns (accents) in all the major dialect regions of the English language as spoken in urban areas of the United States and Canada. It is the result of a large-scale survey by linguists William Labov, Sharon Ash, and Charles Boberg. Speech data was collected, mainly from 1992 to 1999, by means of telephone interviews with individuals in metropolitan areas in all regions of the U.S. and Canada. Using acoustic analysis of speech from these interviews, ANAE traces sound changes in progress in North American English, and defines boundaries between dialect regions based on the different sound changes taking place in them.
