Chrome extension adjusts video speed based on how fast the speaker is talking

Very interesting idea, but doesn't seem to work very well. I tried on three videos. On two it miscounted to an absurdly low rate of ~1 syllable/s and played it at the max speed which was illegible and in one it failed to detect any speech at all.

I have a policy against installing extensions but I might make an exception for this one. I default to 2x and often have to go to 3x if the speaker is really slow. The one exception is music production related videos and it is sometimes excruciating to get through. This is most likely because I'm usually watching some kind of instructional or educational video and just want the content and have no interest in being "entertained". That said, I understand that you have to game YouTube's algo and rules in order to make even a tiny bit of money. Imagine if every channel cut the first 30 seconds of every video intro and everyone could just get to the point.

The extension you are looking for is "Sponsorblock". It crowd sources timestamps to auto-skip intros, ad-reads, credits, etc and is pretty customizable.

You could make a rewrite extension that seeks all video elements to 30s by default. Might not be perfect but it sounds like it would be useful for you.

what's rewrite?

For example: https://addons.mozilla.org/en-US/firefox/addon/re-enable-rig... is a Firefox extension that 'rewrites' webpages to remove 'disable right click' code, https://addons.mozilla.org/en-US/firefox/addon/disable-autop... 'rewrites' webpages to disable HTML5 video autoplay, etc. So you could, perhaps, rewrite the <source src=""> attribute within <video> elements to, if it doesn't already end with #t=x (x is in seconds), to end with #t=30. (Perhaps only the first one? This isn't something I desire, so my investment is limited.)

Or ask gemini to summarize the video instead.
