How do I see the translated subtitles of Coursera's videos?
Switch on the subtitles to see the translated subtitles for the video and select the language you want to see the subtitles in. You will see what languages for a course are available by reading the overview page of the course. If a language is mentioned, it means at least 80\% of the video subtitles of the course have been translated. You can filter your search when you browse for courses, to find courses that have translations into certain languages.
