Twitter’s closed captioning is now available on iOS and Android

Twitter has announced that a button to switch captions to its video player is now available to everyone on iOS and Android. The button that appears in the upper right corner of the video, if it has available captions, lets you choose whether you want to see written descriptions. Twitter began testing this feature in April, but it was only available to a limited number of iPhone users.

For years, whether or not subtitles appear on your mobile device has been determined by a number of factors, e.g. if you have turned on subtitles in your phone’s accessibility settings, or if you watch the video with your sound muted. While still being taken into account, you can now easily turn them on or off whenever you want, just as you already could on Twitter’s website and many other video platforms.

To see an example of the shift, check it out The edge‘s tweet with a trailer for our Netflix show, which has a caption file attached. Employees here were able to see the switch on both iPhones and Android phones, though it could be a bit glitchy – sometimes captions simply would not appear, and at the touch of a button occasionally froze the video.

In another email The edge, Twitter spokesman Shaokyi Amdo said the button “only appears on videos with subtitles already available and not related to the automatic caption system.” Hopefully, the switch, available to everyone, will encourage anyone uploading a video to Twitter to consider adding captions.
