sentences:  North American English is fairly homogeneous compared to British English.Today, American accent variation is often increasing at the regional level and decreasing at the very local level, though most Americans still speak within a phonological continuum of similar accents, known collectively as General American (GA), with differences hardly noticed even among Americans themselves (such as Midland and Western American English).In most American and Canadian English dialects, rhoticity (or "r"-fulness) is dominant, with non-rhoticity ("r"-dropping) becoming associated with lower prestige and social class especially after World War II; this contrasts with the situation in England, where non-rhoticity has become the standard.
