WCAG 2.0 and Transcripts

The word “transcript” doesn’t appear in WCAG 2.0 because it is strictly interpreted as being only the verbatim text version of that which is spoken. For optimal web accessibility for users with auditory disabilities, information in addition to the spoken content (such as indications of laughter or explosions, or the presentation of visual-only content) are necessary. WCAG uses the term “alternative for time-based media” to describe this descriptive transcript. WCAG 2.0 Success Criterion 1.2.3 (Level A) requires synchronized captions and either audio descriptions or an “alternative for time-based media” (i.e., descriptive transcript).
