It does fully support Timed Text Markup Language (TTML) without issue. It also doesn’t support descriptions, but that seems to be an issue with all the other browsers as well.

All browsers seem to have issues with screen readers. The controls disappear after the video playback begins so the person can’t stop the video.

All browsers need to make continued improvements regarding video features for HTML5 accessible video. It is clear the amount of effort Microsoft has made here.  Microsoft IE 11 offer user the best HTML5 accessible video features to date and the accessibility applauds the improvements.
