The social network began rolling out closed captioning for Android and iOS users a few months after it began testing. If the video hosted on the platform has subtitles, you will see a CC button in the upper right corner – just click it to turn subtitles off or on.
Previously, the CC button was displayed on the web and on mobile devices only when the sound was muted. Also, the titles would automatically disappear when the user expanded the video to full screen, as this would automatically start playing the audio.
A few years ago, in order to see the subtitles for a video, you even had to go into accessibility settings and turn on subtitles. However, this feature has a limitation: The button will only be displayed for videos that were originally subtitled.
Twitter introduced auto-generated video captions back in December, which is unrelated to the feature, according to a spokesperson who spoke to The Verge. There is currently no way to report inaccurate auto-generated subtitles.
