Writing Speaker Identification in Captions
Writing Speaker Identification in Captions records a distinct W3C-supported accessibility writing task while keeping implementation mechanics outside the writing guidance.
In captions, identify speakers when knowing who is talking is needed to understand the content, and keep the labels clear and consistent.
Key details
Important caveats
Scope Boundary
Do not add speaker labels mechanically when the identity is already obvious and irrelevant; include them as needed for understanding.
Further guidance
Content
Identify the speaker when listeners would otherwise need the voice identity to follow the exchange, using a clear and consistent speaker label.
Purpose
Relevant speaker identification lets caption users follow who is saying what instead of receiving an ambiguous stream of dialogue.
