There's a bookmarklet for that: https://andrewsteele.co.uk/stuff/youtube-playback-speed-book...

document.querySelector('video').playbackRate = 1.1

SmartTube (for Google/Android TV) used to allow this but a recent update has removed the other speed increments and it now only lets you use the usual increments you find on YouTube. :(

I agree, I like 1.1 speed. The playback dropdown actually has a "custom" button in the top right of the dropdown on the desktop view of the site. You can set 1.05 and 1.1 playback speeds with it. It's a little annoying to use on mobile, as you have to switch to "desktop" view in the browser and can't use the app.

Honest suggestion, try getting used to listening to things at faster speeds.

I started listening to podcasts at increasingly faster speeds, going from 1.1 to 1.2 and slowly increasing it. It only took a few days to a week of listening to slightly-too-fast-for-comfort content before it started sounding normal and I could bump it up again. Now the slowest I listen to is at 1.5 (going up to 1.6 or even 1.8 for my "filler" podcasts). Videos I can crank even higher, since the addition of visual content and/or subtitles can help process the audio information.

I now watch half my videos at 2x speed, and 1.25 or even 1.5 are how 1.1 used to seem for me.

I watch most non action-focused YouTube videos and podcasts at 1.5-2x speed and I honestly don’t lose any comprehension at all with the speed bump

I use this Firefox extension to get 1.10 or 1.15 speed on Youtube: https://github.com/WaldiPL/playbackSpeed
