MACaptionAppearance only.Expand description
A media characteristic that indicates that a track or media selection option includes legible content in the language of its specified locale that:
- transcribes spoken dialog and
- identifies speakers whenever other visual cues are insufficient for a viewer to determine who is speaking.
Legible tracks provided for accessibility purposes are typically tagged both with this characteristic as well as with MAMediaCharacteristicDescribesMusicAndSoundForAccessibility. A legible track provided for accessibility purposes that’s associated with an audio track that has no spoken dialog can be tagged with this characteristic, because it trivially meets these requirements.
