I had a colleague named Lucien. Anglo Australian, so Lucien was pronounced “loose-ee-yun”. But this is not the way of the Australians. The way of the Australians, including his 15 year girlfriend, was to pronounce it “loose”. Spelled, I daresay, Luce.
Australians would have no problem with a woman named thus. But the spelling would be Luce there too.
Hate typing answers on the phone: no IPA.
