In 'rhotic' accents /r/ is overtly realized in a wide variety of phonetic contexts, including post-vocalic environments, such as farm /fahrm/ or far /fahr/. In the non-rhotic accents /r/ is excluded from post-vocalic
environments, thus /fɑ:m/ and /fɑ:/.
The rhoticaccents include those typical of Scotland, Ireland, Canada, Barbados, certain western parts of England, and most of the United States, including General American. The non-rhoticaccents include those typical of
Australia, New Zealand, South Africa, certain parts of the United States, and most of England and Wales, including RP.
