Living in Great Britain afford me great opportunites and having that sort of voice that best describes a Londoner is very second natured in my life. A Liverpool dialect is something that I'm very comfortable with now and have gotten used to. A Yorkshire voice has come natural to me over the years and the same applies with a Manchester dialect. I can do a great Scotsman voice over, Craig Ferguson watch out.
I've also lived in the United States on and off throughout the years and getting used to of how Americans sound has been an interesting challenge. A great example is New York where the dalects are very unique and differ. That wonderful Manhattan voice which has become synonymous with New York is relatively easy for me. A Bronx voice is a little bit difficult, but I've managed to a point where I feel comfortable with it. Since New Jersey is next door to NYC, doing a Boston voice has become somewhat easy as of late. I can also that wonderful southern drawl that identifies the American south. On the west coast, sounding like a california surfer is relatively quite easy.
For other countries I can pull off a Greek accent with relative ease
