Thanks for your quick response. No, I considered using different text captions with specific audio attached to each, and that remains my last option, but the narration is both smooth and lengthy in one piece, and I want to preserve that continuity rather than parsing audio strings in an audio editor to fit each text item.
My goal is to have each text item appear very shortly after that topic is spoken in the continuous narration, and then to allow the user to study the whole screen at their leisure before clicking to move on to the next page. I can set the timing of text items easily in the audio timeline, but then the screen display length is governed by time, not the user action.
