Captioning for Audio files

Just thinking off the top of my head....

1. Global CC btn that sets _ccVar to TRUE or FALSE when clicked.
   
2. Have a timed action that happens every 1s that watches for teh _ccVar for TRUE. If TRUE, set the CC text box to visible, else (the _ccVar = false) then hide CC text box.
   

OR

Global CC btn that sets _ccVar to TRUE or FALSE when clicked and toggles the visibility of the CC TEXT BOX.


I am not entirely sure how to make your text play along with the audio narration, but I am sure you can use a bunch of text boxes and sync'd events with your audio. This is the time consuming part IMO.

Thanks, Andrew. That's the route I was going; however, the issue I was running into was how to separate the captioning by page. The global variable to show/hide the text box is easy to set-up, but would require the text box to contain all the text of the course audio transcript, not just the content on that page. I would need a global button to show a page-specific text box, which I'm not sure how to accomplish.

@clammers, as Andrew says above, you can change the contents of a text box using Actions. Just have an Action on each page replace the contents with that page's transcript (or if you're synchronizing with a video, you could use timed actions to replace it repeatedly).

Yes. That's the idea. I'd even take it one step further because if a user clicks on CC on the previous page, they want it for the entire module and having to click the CC button on every new page become frustrating and detract from the learning experience.

In my solution, _CC is a user created variable to monitor the ON / OFF state of the _CC text box.

• Create a global variable called _CC and set it to FALSE.
  
• Create a global button to set _CC variable to TRUE when _CC equals FALSE, and to set FALSE when _CC equals TRUE.
  
• Create a global Closed Caption Text Box.
  
• Create a global action that runs every 0.5s to show Closed Caption Text Box when _CC equals TRUE, and hides Closed Caption Text Box when _CC equals FALSE.
  

On every page have an action to change the contents of the Closed Caption Text Box when page is shown.

There are many ways to do this, but that'd be my method.

Adding the text to the Change Contents action should be the only way to achieve it without custom js.

The textbox has no rule for overflow, so the text is visible if it is longer than the height of the div. Do you have "Vertial scroll" activated?

Can you post your content?
