Apropos of the post: sometime back I had wondered if it would be possible to search videos for content by text keywords, but not to match text occurring in the video title, chapter titles or comments. Instead, if an app or library could somehow search for the given keywords by matching them with the spoken words in the video. That would be a potentially cool and useful feature. I realize this may be technically impossible [1] or very difficult, but thought of mentioning the idea here. [1] On further thought, speech recognition (as seen in mobile phones at least) has progressed to quite a good level (speaking as a layman for this part), so maybe the idea is not wholly infeasible. If an app or lib could somehow "internally" play the video, and speech-recognize the spoken words into text, then the problem would reduce to normal text pattern matching. Putting the idea out here to see what devs think of it.
