Software that eats video and gives out subtitles, is there such a thing?

Question

Machine translation from one language to another

Since spoken English is more difficult to perceive than text, I am looking for software that eats a video file and produces subtitles.
I found an addon for the SpeechLogger
browser Once on the forum I saw a discussion about the translation of courses with udemy, lynda, etc., that the translation was automatic and monotonous, so the software is there, but what is the name and where to look?
