Sociophonetic analysis pairs the demographic, geographic, and sociopolitical components of sociolinguistic inquiry with instrumental phonetic measurement techniques. This paper applies sociophonetic analysis to the study of regional vowel variation in African American English. Previous research has established robust variation in White American English.

Findings are discussed with respect to the Southern Vowel Shift, the hypothesized African American vowel system and a proposed omniscient observer effect that directly impacts vowel production in African American English speakers in the United States.
