I think this feature would give a person more time to immerse since scenes where nothing is being said will be skiped.
You can right click (or press D) on your keyboard to skip directly to the next speaking scene. But your request is interesting !
Here is an mpv script that does that for inspiration.
Seconding this. Great for free flow rewatches and passive listening while doing stuff that tie up hands. Even better if the condensed audio can be downloaded to play offline, but maybe there are some copyright issues with that. There are some programs out there that do it, but they’re all too complicated for me to figure out. I like LLR intuitive ease of use #1.
Looks like this idea has been around a while and lots of community support Continuous playback but skip parts with no dialogue
