Display lyrics of a song

Hey all !


My question has nothing to do with upcoming Apple Music feature that will display lyrics of a song while you listen to them.

It is not that far.

Actually, we create audio stories, and we would like to display the text of a sentence as the comedian says it.


Ideally, I would like to have it working with the audio file (obvisouly), and a text file with the text and the timing each sentence should appear. (actually, this could look like a caption text file, except I don't have any video to play, only audio).


Do you, smart guyz, have any clue on what would be the best way to achieve that ?


Thank you very much if anyone could point me to the right direction.


Have a nice day.
