English accents are slowly becoming more southern, study finds
Regional accents across England are slowly fading, and are being replaced nationwide with a more 'southern' way of speaking, according to research.
The accent data was gathered from 30,000 users of the English Dialects app, created in January by Cambridge University academics, and compared to the results of a dialect survey carried out in the 1950s.
People from across the country answered the survey through the app, which asked them to specify how they said certain words like 'scone', and how they referred to certain things, like a 'splinter'.
