Storyline and Web Content Accessibility Guidelines (WCAG)
1.2.2 Captions (Prerecorded)
Captions are provided for all prerecorded audio content in synchronized media.
Supported. We recommend that authors use triggers to display a caption text box synchronized with the media. The display of the text box is controlled by a variable on the slide master.
Upon my review of your application against Lectora, Captivate, Camtasia the Articulate method for providing closed captions is free hand and can not guarantee that it will always be ADA Complaint. As well, it does not export or import standard caption file formats.
As a result, our team has been using Camtasia a forced restrictive application that prevents mistakes when implementing CC for ADA Compliance. The following link is how Camtasia can state it is ADA complaint.
Personally, I found it frustrating attempting to implement the Articulate Storyline 2 method as it actually causes double work because it can not import an existing ADA complaint CC file.
Does the Articulate Storyline 2 Team have something in the works or is this not on the radar?
All the best,
