Well not really because of the lack of a phonetic sound,most people can tell where somebody is from the moment you hear them speak.
Irish,Scottish,Welsh,Geordie,Scouse,Cockney,Brummie,even down to being able to tell where in Scotland a Scot actually lives (somebody from Dundee sounds very different to somebody from Glasgow).
It's very,very hard to determine that somebody is from Yorkshire without being told. The classic mistake is thinking somebody from Lancashire is actually a Yorkshireman because of that t' thing,if you take that t' out of the equation (because it isn't a Yorkshire thing) then it's near on impossible to tell who's a Yorkshireman.
