I am an English language learner.
I encounter serious problems when watching a lot of English language videos. Some speakers talk so fast that I do not understand exactly what they are saying.
Of course, some videos in YouTube have online subtitles, but when I download them, the subtitles are not downloaded with those movies.
Therefore, this is my question:
Is there a way to process an English video & add English subtitles automatically? (A combination of google transtale that automatically write what you're saying and YouTube online subtitles)
NOTE: I'm not looking for sites like Subscene, SubtitleSeeker etc. Because I'm not actually watching movies or TV series, but I'm watching scientific videos which actually do not have any prepared subtitles and most of them do not exist in YouTube(So this is not a YouTube-problem).
I'd appreciate your comments & suggestions!
