How to pronounce “supertitle” in English

There are other operas like Puccini and Bizet where the sound of the words is really important to the way the music is structured,so it becomes a little more difficult to translate, so then we often do supertitles.But in the case of "Fidelio" or "Carmen," for example, where it's a mixed opera with music and dialogues, we always translate the dialogues.
