My Colonial Latin America professor was Argentinian by birth, but had received her graduate education in England. She had the most wonderfully subtle, lyrical accent as a result. British English ( with the accent ) with an overlying Latin accent. Just fascinating to listen to.
My father’s partner had been an army medical officer in WW I. He met and married a French nurse and brought her back to Bellefontaine, Ohio, where they lived in a house sized apartment over the office. She was a charming lady with a tremendous French accent that would have been the envy of every actor who ever had a part in Gigi. I last saw her in 1966. She was an old lady then, with emphasis on lady. No one, my father included, never called her anything but Madam Pratt, never by her first name.
For American accents, nothing is more charming and gentile to my ear than the Virginia Tidewater accent
I had a camp counselor who was Dutch (from The Hague, I think) and I loved her accent.
Not an accent I enjoyed, but certainly out of the norm–my French (from France) teacher in junior high had sort of picked up an accent from her Brooklynite husband–that’s a voice I would flee from if I heard it again.
I don’t mind Southern (US) accents as long as they’re not too twangy.
I have a teacher’s assistant from Croatia whose accent I love. Its’ like a bouncy German.
To Drayton: Serbo-Croatian, like Swedish, Norwegian, Yoruba, and Chinese is a ‘tonal’ language. Someday I’ll hear someone speak it…

I remember something like that from the senior year of high school at Redondo Union HS in Redondo Beach, CA. October 1966. Among the people in the cast for the senior play was a girl named Patricia who was an exchange student from South Africa. Some other girl told me she heard Patricia speak and asked her if she was from England. The South African girl was apparently offended; even then I could understand why: In the 50s and 60s South Africa broke with the UK over the apartheid issue. I was in the cast myself, but I knew better than to mention England to her or discuss international politics with her.
I never realized how incredible HOT the Scottish accent is (on ladies, that is) until I visited Glasgow for the first time. Wow. I was blown away with how easily it was to be smitten by those lovely, lilting cadences. And paying sharp attention to make sure you understood what was being said only made it worse! Easily my favorite.
Ditto the comment on Fiona Ritchie–the only bad part of her show is I actually get tired of the music pretty quickly; it’s nothing compared to her voice.
