The operational decision
Let viewers understand the demonstration without relying on audio. Accessibility review starts with the actual task a visitor needs to complete: finding an entrance, reading hours or contacting staff. A polished appearance alone does not show that the information can be used.
Prepare the workflow
Provide a checked text version of the spoken example, identify speakers and label the result as fictional; do not publish a real patient call.
Example wording for approval
“Demonstration: a fictional caller asks about public parking information. No real appointment, patient intake or clinical instruction occurs in this example.”
Worked example
A silent viewer sees a friendly waveform and a result card but misses the spoken warning that the office is fictional. Add that meaning to the visible introduction and caption track, along with speaker labels. Compare the transcript with the final audio after any edit; an older caption file can describe a different parking answer. The published example should communicate its scope and result without sound, and it should contain no real caller recording used as background material.
Handoff record
Record these task-specific fields: video version, transcript version, speaker labels, reviewer.
Acceptance check
Watch the demonstration muted. The scope notice, caller question and office-information answer should remain understandable from the captions and surrounding text.
