Question

Optional audio with Closed Caption

We would like to have the optional audio for the learner, using a button, so they can listen if they'd like to. As well, we need the closed captions to also work in sync when the play button is clicked if they decide to listen. I cannot figure out a way to all three of these at once:

1. Create closed captions

2. Only have audio play when a button is clicked

3. Have the closed captions sync up with the audio since they would be related to the button rather than the slide audio/timeline.

    You can toggle the system variables cpCmndMute (Boolean = 0 by default, but when toggled to 1 audio will be muted) and cpCmndCC (depends on the setup of CC whether it is on by default or not - also a Boolean. CC is always synchronized with slide audio, I don't know what you mean by 'related to the button'?

    If you want CC and audio off to start with, use this action On Enter:

       Assign cpCmndMute with 1

       Assign cpCmndCC with 0

    If they want only ausio:

       Assign cpCmndMute with 0

    If they want Audio and CC:

      Assign cpCmndMute with 0

      Assign cpCmndCC with 1

    Lilybiri,

    We would like the learner to be able to choose for both audio and close captions. They can choose whether to listen to the audio or just read what is on screen. As well, they can choose to turn on the close captions. So these are the choices for the learner:

    1. No audio, no captions

    2. Audio, no captions

    3. Audio and captions

    If the audio and close captions are off On Enter, how would the learner access to listen to the audio and/or turn on close captions?

    You have to add buttons of course, and trigger the actions I described with those buttons.  I would recommend buttons on the master slide or timed for the rest of the project, which means you need shape buttons.
