The three most broadly recognized dialect areas of American Regional English are currently being re-de®ned by, in some cases, sweeping changes that alter the way vowels are being pronounced in the South, North and West. While research into the changes in urban Northern dialects has contributed a fairly broad picture of both the phonetic and social character of the Northern Cities Shift (NCS), the changes aecting the Southern region of the U.S. have received less attention, particularly in terms of social distribution and dissemination. This paper seeks to address the question of how successfully changes in the high and mid front and back vowels in the South are being disseminated throughout a local urban community and how these changes ®t in with changes occurring in other American dialects. In addition, the paper weighs the attraction to local or national norms in determining the success and diusion of each of the shifts relative to the social environment in which they are developing and attempts to relate the local social embedding of the shifts to their meaning in the larger national context.
