English language in southern England
South East England and the Home Counties (the counties bordering London) tend to reflect the interface between the London region and other regional accents. Affluent districts are associated with a modified Received Pronunciation (RP) accent, reflecting their traditional popularity with upper middle and upper-class residents which has spread throughout more social classes broadly in rural areas with commuting access to London. Less affluent areas have traditionally mainstream London accents (that is, variants of the Estuary English accent) that grade into southern rural outside urban areas.
Cardiff English
Cardiff English shares many phonetic traits with the English spoken in the Severnside area of England, but differs in being non-rhotic. A notable characteristic in the accent is the lack of rounding lips when pronouncing consonants and vowels. While in Received Pronunciation, lip-rounding is a common feature to distinguish vowels, in Cardiff English this is not often observed.
