How to play Voice narration one time on Table of content page?

[shahwara31683347]

I am designing a course on the all new Captivate -12.4 version. I have the menu page centralized in the course in a way that the learner needs to go back to this page evrytime he completes a module, till all modules are done to have the test button appear. The voice plays everytime the participant returns to this menu slide. How do I have the voice naration played once only?

Any ideas please?

You can set up a true/false variable, witht the default state to true.  And set the interaction so that when the variable is true the narration plays (resume timeline), and when it is false, it doesn't play (pause timeline).  Then on the the buttons that return learner to the main slide, add an interaction that changes the state of the variable to false.  Then when they first visit that slide the variable is true and the audio plays, every time they come back, the variable will be false and the audio will not play.
