dialect is the keyword as opposed to accent.

I had been in England years ago
but when I went a few years ago I realized how different
a language the Queen's English is from North American English.
Further, each region of England is very different. I further
realized how different the dialects are within the US.
I'm from NY, live in the Republik of Kalifornia and probably
a few times a week I still get asked to repeat something due to
my accent (I usually reply, "Accent? What f**kin' accent? I
ain't got no accent. Where's you's accent from? ).
