About

You can order extended audio description (EAD) for videos with limited natural pauses or dense visual content. EAD pauses playback to insert detailed narration of visual elements, then resumes the video when the narration is complete.

EAD uses speech synthesis to generate narration from a time-coded VTT file. Most browsers support speech synthesis, but some may not. To check browser compatibility, visit lambdatest.com.

The video below features extended audio description.
