They are the same.
"Bean Sidhe" is modern Irish spelling of "banshee". You can also see it spelled "banshie", "bean si" or "ben sidhe"; people of Scottish persuasion sometimes write it as "ban-sìth", "bean-sìth" or"ban-shìth". I believe that there are slightly different spellings of it from east Munster and Isle of Man, but I do not remember those exactly and I am away from my books at the moment.

Although I have probably already added far more information than you really wanted, I can add that the terms mean "fairy woman" or "woman of the fairy mound".




As for Latin pronunciation, I have found that discussing that is a sure-fire way of getting shouted at by fanatics that all present slightly - or very - different versions of the only true pronunciation. As far as I know, though, Latin was around for quite a long time and pronunciation did differ between localities and over time. And probably between social groups, as well.
