The Cardiff accent, also known as Cardiff English, is the regional accent of English, and a variety of Welsh English, as spoken in and around the city of Cardiff, and is somewhat distinctive in Wales, compared with other Welsh accents. Its pitch is described as somewhat lower than that of Received Pronunciation, whereas its intonation is closer to dialects of England rather than Wales.
It is estimated that around 500,000 people speak Cardiff English. The accent is generally limited to inside the city's northern boundary, rather than the nearby South Wales Valleys where the spoken variety of English is different. However, the accent area spreads east and west of the city's political borders, covering much of the former counties of South Glamorgan (Barry) and south-west Gwent, including Newport and coastal Monmouthshire.
