Okay, so this is a 'necropost' par excellence, but god knows, this section of the forum is in desperate need of posts of any description.....
If you want to get a few pointers to the 'Yorkshire Accent', you could do a lot worse than to watch a few old episodes of the long-running UK soap opera Coronation Street from the 1970s and 1980s (quite a few of them on YouTube). Several of the characters have this accent, for example Alf Roberts, Ivy Tilsley and Vera Duckworth (also David Platt in more recent years). The show is set in Manchester, where Yorkshire accents are rarely heard, but the actors who played these characters were from Yorkshire, and spoke in their native accents.
I think the Yorkshire accent may have been taught in drama schools as some kind of generic, all-purpose accent for Northern England, though that is not the case in real life. I once watched several episodes of The Onedin Line, a 1970s BBC drama series set in Liverpool, and noticed that almost all the characters spoke in a Yorkshire-type accent, which is nothing like the real Liverpool ('Scouse') accent.
A very reliable test as to whether a person has a Yorkshire accent is to ask them to count to five. Four of the five numbers have a very distinctive sound, in particular 'one' and 'two'. The number 'one' is pronounced 'wun', for example. When the London actress Michelle Collins appeared in Coronation Street on a regular basis a few years ago, she always pronounced 'one' as 'wun': this would have appeared ridiculous to Mancunians, but people in most other parts of the country probably never even noticed.
