While driving home yesterday I was listening to an interview on BBC Radio Norfolk with one of the people behind the English Dialects app . They were explaining the way that it works, by listening to particular words and how they are pronounced, and also the emphasis on vowels, along with local dialect words. There are a few of these in the quiz, such as the choice of word for a 'splinter' of wood that might get stuck under your skin... is that called a spell where you're from? There's a Telegraph article on the app here. I had a go and submitted my answers and location - it was not too accurate, but then I've spent half my life in Yorkshire and (just over) half in Norfolk - which are two quite different dialects... and have a sort of neither one nor the other accent... Interesting to try with students perhaps if you have airplay...
