Our islands are rich in regional accents - many of them music to the ear! I came upon this clip via Gretchen Rubin, and it's a whirlwind tour round some of the country by accent and dialect coach Andrew Jack, but it gives a sense of the marvellous range and variety we have in Britain.
It reminded me of a story the novelist J.I.M. Stewart (Michael Innes) told in his autobiography. Stewart was at a dinner at his Oxford college at which the special guest was a renowned phonetician. This man - Professor Higgins-like - could pin down a person's origins within a sentence or two of hearing them speak, a feat he demonstrated with uncanny precision as he went round all those seated at High Table. Finally, he reached Stewart, a man born and brought up here in Edinburgh, but who had since spent twenty five years away from his home city in places as distinctive of accent as Australia, Yorkshire and Northern Ireland. Surely these strong and diverse influences would tell on his speech. Stewart began to talk, but the phonetician stopped him with a pointed finger and the flat tone of authority: "Edinburgh," he said, and then with undisguised glee he homed in even further, "the Edinburgh Academy!" Sure enough, that had been Stewart's school.
By the way, if you follow the link above to Andrew Jack's site and scroll down to the video on the homepage, you'll hear him talk about his involvement with the languages and accents of Tolkien's Middle Earth in Peter Jackson's Lord of the Rings films.
