Marking Omitted Irrelevant Speech in Captions
Marking Omitted Irrelevant Speech in Captions records a distinct W3C-supported caption-writing task while keeping implementation mechanics and unsupported house-style rules outside the guidance.
When speech is not relevant and is intentionally left out, W3C WAI recommends indicating that the speech has been excluded rather than silently creating an unexplained gap.
Key details
Important caveats
Scope Boundary
Only omit speech when it is genuinely non-substantive for the content and the chosen level of detail permits it; legal or verbatim contexts may require fuller transcription.
Further guidance
Content
Use a concise bracketed omission note that tells the reader what kind of irrelevant speech was excluded.
Practical Application
When the chosen captioning approach permits genuinely irrelevant speech to be omitted, insert a concise omission note rather than leaving an unexplained gap. Keep substantive speech, and follow stricter verbatim requirements when the context calls for them.
Purpose
The note preserves continuity and makes the editorial omission transparent to caption users.
Reader Check
Would a caption user understand that speech occurred but was intentionally excluded, rather than assuming audio was missing or the captions failed?
Worked Example
If unrelated background conversation is intentionally excluded under the project’s caption policy, insert a short bracketed note indicating that irrelevant speech was omitted instead of jumping silently to the next spoken line.
