I'm from Hull and we have our very own unique breed of a Yorkshire accent which is just... something else.
I don't think my accent is very strong, and other people comment that I do have the accent but I don't sound as bad as others.
You really know a Hull accent when they pronounce "Phone" as "Fern" and we are notorious for saying "Nerr" instead of "No"
I got picked on at school for saying Lunch instead of Dinner so people thought I was posh

My partner is from Kent so his accent sticks out like a sore thumb here, his accent is not dissimilar to Essex, but I think it's a bit more mellow.
On the other end of the scale I had a friend who lived just outside of Hull her whole life, both parents were Scottish but I have no idea what to class her accent as at all. It's slightly posh, but there is no Hull or Scottish twang. I wouldn't even call it a Yorkshire accent. It's baffling.
