Accessibility: timeline with voice over and without.
I am building an accessible e-learning course with voice over equal to the text on the slide.
Here is my dilemna:
For learners who can hear the VO, the timeline will match with the VO and all text and objects will appear at the same time with the right VO.
But for learners who won't hear the VO (deaf people, no headset, on old computer in remote area in developing country - for NGOs, etc.), they will see all text appear with a feeling of big laps of time between each object or text, as they have to wait the voice over end up before the next text/object appears.
I am actually designing my course matching for "no VO people", with a timeline pace matching for reading, which is much faster than for listening. So the guy with VO will see the text/objects appear faster than the voice.
Any advises about it ?
Thank you so much,
