I watch Chinese drama. I love wushu series. One of the problem with it is that they are very long regularly 52 episodes. Long is usually good. But since I do not speak Mandarin I have to focus and read the subtitles. It is exhausting experience.
Most video now a days come with subtitles. And we now have speech technology that can read very fluently. It should be matter of matching subtitle to the timing and have the software read in real time so I don't have to strain my eye.
This is something that can be done now.
