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.

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.
