I tried to find an online dictionary for Latin that includes clear and reliable pronunciation information given with IPA symbols. Despite several attempts, I was not successful so far. Does anybody here know one? I know, Latin pronunciation rules are not that difficult and can be found in several places like in Wikipedia http://en.wikipedia.org/wiki/Latin_spelling_and_pronunciation, but already with the pronunciation of the vowel a I got into problems: Some sources give the pronunciation as /a/ (open front unrounded vowel), but some others as /ɑ/ (open back unrounded vowel), like e.g. this quite interesting Latin-to-IPA transcriber: http://fgasper.freeshell.org/latin_engine/ Or do these different pronunciations of the vowel written as "a" simply belong to two different periods or versions of Latin, like classical versus Church Latin?
