American English
American English varieties form a linguistic continuum of dialects more similar to each other than to English dialects of other countries, including some common pronunciations and other features found nationwide. Any North American English accent perceived as free of noticeably local, ethnic, or cultural markers is popularly called "General" or "Standard" American, a fairly uniform standard of broadcast mass media and the highly educated. Otherwise, according to Labov, with the major exception of Southern American English, regional accents throughout the country are not yielding to this standard, and historical and present linguistic evidence does not support the notion of there being one single "mainstream" American accent. On the contrary, the sound of American English continues to evolve, with some local accents disappearing, but several larger regional accents emerging.
