Subtitles and closed captions open up your content to a larger audience, including deaf or hard of hearing viewers or those who speak languages besides the one spoken in your video. If you already have captions or subtitles, get help editing or removing existing captions.
Add your own subtitles & closed captions (please create your own youtube account for the department if you don’t have one)
