Just so we all understand what we mean and who requires (or should require)
There are three type of text
1) Transcripts - (usually refers to static documents that represent the
spoken text only - occasionally with sounds)
2) Captions - Synchronized text of audio and sounds
3) Full Multimedia Text Alternative (including any interaction) - which is
like a screenplay. It is a static text document that contains all of the
speech, all important sounds, and a description of all of the important
visual information - as well as links if there is any interaction that
occurs in the multimedia.
In WCAG we require
At Level A
- Captioning for pre-recorded multimedia
- EITHER Audio description OR full text alternative for multimedia
including any interaction for Pre-recorded Multi-media
- a transcript (static) for prerecorded AUDIO-ONLY content
- a text description (static) for pre-recorded VIDEO-ONLY content
At Level AA
- Captions for LIVE multimedia
- Audio Description for Pre-recorded Multi-media (if you didn't already
provide it to satisfy Level A)
At Level AAA
- full text alternative for multimedia including any interaction for
Pre-recorded Multi-media (if you didn't already provide it to satisfy Level
- Extended Audio Descriptions (stopping video as necessary to get full
audio descriptions in)
- Sign Language interpretation of all speech and sounds in Multimedia
full text alternative for multimedia including any interaction
document including correctly sequenced text descriptions of all visual
settings, actions, speakers, and non-speech sounds, and transcript of all
dialogue combined with a means of achieving any outcomes that are achieved
using interaction (if any) during the multimedia
Note: A screenplay used to create the multimedia content would meet this
definition only if it was corrected to accurately represent the final
multimedia after editing.
