I vary to be honest. Both accent and dialect will wander around the country depending on my mood at the time, and what I think will sound most effective!

Answers given are my default settings (as it were), although my Yorkshire accent thickens up quite regularly. In fact, the Yorkshire accent is as much an affectation as any other. Whitby, where I grew up, has an accent that is all its own, and I don't speak that naturally at all - I didn't like the accent growing up, and so decided not to adopt it. My sister on the other hand speaks nothing but.
