Like most people, mine varies according to who I am talking to.
I sound like an NZer if I am talking to kiwis, more my native Leicester if I am talking to other Lestohs. A bloke even commented that I sound like an NZer when I'm talking about NZ - which struck me as quite bizarre! To others, I suspect I sound vaguely midlands/north-ish with occasional Kiwi vowel sounds... but difficult to place.
It was recently remarked upon that my French sounds local. That is, Berrichone. It means I sound like a bit of a yokel to the sophisticated Parisians!
Guess I'm just a bit of a mimic and adjust to blend in as much as possible.
