Abstract
The English Language, being an international language, is spoken all over the world with many variations. These variations occur primarily due to environmental, cultural and social differences. The main reasons for these variations are intermingling of different races and strata in a society. In this regard prominent differences can be observed at phonological levels. These phonological variations produce different kinds of English, like British and American English. In these two there are differences in intonation, stress pattern, and pronunciation. Although South-Eastern British R.P. is known as Standard English but one cannot deny the existence and value of American English. The study attempts to highlight the vowel variation between British English and American English at phonological level.
