Subtitles are fundamental for deaf users and useful for users who cannot unmute themselves. They can be read by the screen reader.
Objectives
Allow users who cannot access sound or who are deaf to have a visual alternative synchronized with the image to comfortably follow the progress of the video without having to use an external transcript.
Make the video accessible
Implementation
Associate synchronized subtitles with each video content including at least the information given by speech.
Control
Check, for each video content providing information through speech, that it can be read via synchronized subtitles.
