Speak Subtitles for YouTube
Reads YouTube subtitles out loud with synthetic voices in many languages, so you can listen to a video instead of reading captions.
Chrome extension
Translates YouTube captions into your language and speaks them aloud as the video plays, acting like a live interpreter.
SimIntpr translates YouTube captions into your language and reads them aloud with synthetic voices while the video plays in Chrome. It is for viewers who want to hear a video in their own language, much like listening to an interpreter.
Open a YouTube video, choose one of its official subtitles as the source, then pick your target language and voice settings in the extension.
The video must have at least one official subtitle track for it to work. Synthetic voices may not capture tone or names accurately.
