Learners who are deaf, using hearing aids, or non-native speaker learners are likely to benefit from videos annotated with script more than ordinary videos.
Subtitles are in (WebVTT) format for screen readers.
This channel is starting to collect human annotated videos (http://www.youtube.com/user/Annotationify).
