In 2010, William Labov noted that Great Lakes, Philadelphia, Pittsburgh, and Western accents have undergone "vigorous new sound changes" since the mid-nineteenth century onwards, so they "are now more different from each other than they were fifty or a hundred years ago".

Rather than one particular accent, "General American" can be defined as any American accent that does not incorporate features associated with some particular region, ethnicity, or socioeconomic group.

Typical General American features include rhoticity, the "father–bother" merger, "Mary–marry–merry" merger, and pre-nasal "short "a"" tensing.
