I received the following email last week concerning Adobe Captivate and accessibility.
Hi,
On page 75, Adding Accessibility Text to Slides you state, in step 2, that …”Screen readers will not see slide background images. When a visually impaired learner accesses this slide, the assistive device reads the Slide Accessibility text aloud.”
Following this statement in the instruction below, you have us type what looks to be the script of the narration into the Accessibility dialog box.
I am a bit confused by this. If my module includes a narration (voiceover audio) and closed captioning of the narration, what additional information should I include in the Accessibility dialog box? Do I also add the narration there too or do I simply add descriptive text only to explain what the image of the slide is?
The developer's email above is referring a slide's Accessibility dialog box which can be accessed via the drop-down menu at the top of the Properties Inspector.
Once the Accessibility dialog box is open, you can type anything you'd like, import the text from the slide notes, or copy/paste the text from an existing voiceover script.
I am frequently asked why it's necessary to add Accessibility text if a lesson already has voiceover audio and closed captions. It's a great question. Keep in mind that closed captions are intended for a person with a hearing disability. If the learner has a visual disability, the closed captions aren't going to offer any assistance.
Let's pretend for a moment that you are visually impaired. You will rely on a screen reader to read aloud what you cannot see. The voiceover audio, even if it features James Earl Jones, isn’t meant for you. In fact, the cadence of the words spoken by Mr. Jones would likely be sooo slowwwww you’d go nuts and probably fast forward through the lesson.
Accessibility readers read at a much higher speed than most people without a disability can handle. It's a best eLearning practice that the Accessibility text be identical to the voiceover audio. When a hearing impaired learner accesses your content, most will mute the audio being used in the presentation (meaning they will not hear the Mr. Jones at all). Instead, learners will rely on the accessibility text (which is read aloud by a screen reader even if the audio is muted in the lesson).
