Some users cannot hear the dialogue or sound effects clearly or at all.
Provide an alternative for the dialogue and sound effects
This affects people with hearing loss or deafness. It also happens to people in a noisy place where it is hard to hear, or a quiet pace where you cannot turn up the sound.

Sign language videos can be played alongside, or inside, a video
Make sure you don't need sound to understand the video.
