EdgeEX features over 130 languages for translation. When a student has translation enabled in their profile settings, they can change the language of most on-screen text, including the video transcript and captions (but not the text that appears in the video itself). In addition, EdgeEX features persistent translation (that is, the student does not need to click Translate page by page). Both caption translation and persistence are features unique to EdgeEX.
Included languages are listed in the table below.
