Text Synched with Audio in Storyline

Hi guys!

I have a dilemma :) So I created a Storyline interaction for one of my courses where I have a base layer with multiple layers. On each of the layers, I have some text, bullet style, that the learner will have to go through and a text-to-speech audio that basically reads the text on the screen. What I did was to synch the text on the layer (with entrance animation) to the audio that is being played - using cue points. The dilemma comes from the fact that, for a better user experience, I want to give the learner the possibility to stop the audio in case they want to - again I was able to do that by adding a button to stop the audio. Buuuutt....if the learner stops the audio then the text will still appear with the synched animation which means it can take some time for the entire text to appear on the slide - and can give the learner the impression that they're done reading when actually there was more text there. Is there a way to maybe have both of these features: text synched to the audio AND having the possibility to stop the audio? Thanks in advance.
