Youre looking for Bismuth, the technical speedrun communicator. Hes perfect in everyway.

Also theres Tomatoanus, also speedrun comminicator, excellent work.

Isaac Arthur is a futurist I like for this, hell give you wonderful dreams.

3blueonebrowns visual communicatio style is excellent but ive fallen asleep to his videos tons of times.

Chyrosan22 has the voice of God and he reviews mechanical keyboards, absolutely love it

Donoteat01, justin rosczknyaiacs channel, has perfect shit in his Power Planning and Politics series, hypnotic, funny, and entrancing

Drachinifel is a naval historiographer whos excellent, highly reccomend his video on the second pacific sauadron

Emplemon also has some excellent content

Food Wishes is chef johns youtube channel and he has a very unique way if talking that i love

Hypohystericalhistory has excellent longform documentaries about warstuff

Hope thats enough thats off the top of my head and is through H of my subscriptions lol

I'm surprised no one has mentioned VaatiVidya yet. His voice is so calm and relaxing, he's a fantastic narrator. His content is mainly lore about FromSoftware games like Dark Souls and Elden Ring.

Northernlion's Binding of Isaac series is notorious for putting people to sleep regularly. Definitely a must-listen in my books

Ooh my time to shine with my long list

1. T90 Official plays age of empires games very soothing voice
2. Agadmator plays chess videos very rhythmic voice
3. 3blue1brown maths videos, even if you hate math he has a voice that is so calm
4. Real Civil Engineer plays indie or building games is a bit weird, 90% he is nice but sometimes he gets excited and I've been woken from my sleep, but still good as I fall back right after
5. Kurtzgezat science videos with great narration (may hurt your dreams tho)
6. Nicole Coenen woodcutting videos great voice great pace only downside very few videos in total so you burn through her videos quite fast.
7. Technology Connections, great videos about obscure day to day tech mazing voice
8. Primitive technology, no words a lot of nature sounds of him building stuff without technology

I'll add more if I remember.

The narrator from the game the Stanley parable

has one of the most smooth voices I've fond. Very chill process even to watch.

I also find very soothing.

https://www.youtube.com/@Luetin09 and https://www.youtube.com/@baldermort for Warhammer 40K stuff. But that may break rule 2

https://www.youtube.com/@ScottsThoughtsPokemon for Pokemon Yellow playthrough with every Pokemon and back porting some gen 2 Pokemon to gen 1.
If you prefer red and blue there is https://www.youtube.com/@Jrose11 but his voice may not be rule 1.

perun

If you've ever been in the military, and had to endure hour-long PowerPoint presentations, and felt very sleepy... This guy is for you.

Perun does deep dives into defense economics, for modern-day conflicts. Extremely interesting stuff. Easy to fall asleep to. Highly recommend.

Death by PowerPoint!

Joe Pera Talks You Back to Sleep

The whole series isn't on YouTube, unfortunately, but it is SO worth your time and fits the bill like nothing else.

Pete Complete, in particular his RimWorld series. His voice, relaxed tone and slow pacing with a lot of pause in his speech puts me to sleep even when I'm not trying to.

I watch a lot of tech related youtubers to fall asleep.

Techmoan, LGR, Bigclivedotcom, Usagi Electric, Tech tangents, technology connections.

Non-tech related youtubers: Baumgartner restorations, atomic shrimp, ashens

Professor David Kipping and his Cool Worlds youtube series / podcast.

https://www.youtube.com/@CoolWorldsLab/featured (sorry, linking to the channel instead of a specific video so can't use piped it seems

Try Drachinifel. It's about ships and naval stuff from previous centuries. Best sleep. https://youtube.com/@Drachinifel?si=hiHGva5RXNeSVopY

My big two are long form chemistry videos (codyslab, nilered) and old archived hours of the first version of the AI show Nothing Forever. Very easy listening IMO and should hit most of your bases. Maybe also look for podcasts on a topic you like, those can be hours long

Ethoslab and Docm77 are both older Minecraft YouTubers who have a pretty chill voice and calm demeaner, Etho especially.

Here are some I enjoy. All have a good voice, not overly expressively and no sudden change in background tracks. No sudden screaming/explosions/anything that will wake you.

John Michael Godier Science/Speculative Scifi, Low Soothing voice, even has a sleep playlist.

Issac Arthur Sci-Fi, Calm voice, Good background track, Long Videos

Darth Gandalf Fantasy, Soothing Voice

Forgotten Weapons Firearms, Historical and Mechanical overviews and indepth discussions. I recommend you skip the shooting range stuff if you're trying to sleep.

Cool Worlds Science & Astronomy. Great Narrative Voice, Calm background tracks.

North02 Science, Anthropology & Natural history. Soothing Voice, nice selection of long videos.

Natural World Facts Deep Sea biology, excellent soothing narrations, very good soothing background tracks.

The History channels:

• History of the Universe
  • Found them on this channel
• History of the Earth
• History of Humankind
  • This is their new channel that they started just a short while ago.

It's really good long form fomat. You don't have to watch anything and just listen. It's long enough for me to fall asleep and not hear the whole video so next night I just go close enough to the end of what I heard/remember I heard and just continue listening. I don't mind relistening at all - I always miss something so I always learn something new.

Edit: the awesome thing is that these videos are told basically like a story. The narrator's voice is calming, there are no loud noises or anything. He really tells it like a good night story.

Dan Olson

If you like D&D then I can suggest D&D Deep Dive - roughly hour long videos building weird combos for D&D play but with the smoothest voice ever!

Didn't see Baumgartner Restoration here yet. Incredibly soothing art restoration

John Michael Godier, great sleep ready content about science and science fiction. One of my faves.

Thevolgun... Just don't listen to the really scary scps .....

If you like video games, try a search for a video game of choice and add the words "role play".

I was playing a lot of Kenshi and I found some YouTubers who make long playthroughs of games. Specifically I enjoyed Rycon Roleplays Kenshi which was something like 80 videos and each about an hr long. It would put me to sleep.

For speeling purposes have you tried ASMR content?

For example Let's Find Out makes ASMR content focused on anstronomy and physics stuff and mainly whispering things. Example: https://youtu.be/U6M7_Pt0d14?si=0By2q3YJ-r95K0TD.

You also have The French Whisperer ASMR, who does a bit of everything (history, some science, reading stories...)

For pure ASMR (but non informative nor anything) RaffyTaffyASMR puts out some solid content.

Let's talk religion. Barely sociable. Lemmino

I should mention audiobooks. I love listening to audiobooks, and sleeping to them is also great. There's some excellent works out there, especially voice work by Steven Fry, that's just magic to listen to.

https://www.proofreadingservices.com/pages/audiobooks-read-by-stephen-fry

"The Why Files" and "Kutzergart".

If I'm really not ready to sleepy, I find the content interesting. If I am ready to sleep but my brain won't shut down then I ignore the words and I find the voices very soothing and relaxing.

I love Wendigoon, he does interesting long term stories and is really calm

Madseasonshow. I found him when World of Warcraft Classic launched a handful of years ago. Thinking about it, he and Joe Pera have a very similar speech style.

I listen to my favorite British game show (QI and "8 out of 10 cat's does countdown") or the 10 hour loop of Joe Pera talks you to sleep https://youtu.be/91wX0NRjJqg?si=aMDe0U0oyoNmAbVR

Honestly Kitboga is just so soothing to listen to

I've heard there are a lot of people who listen to PBS Space Time to fall asleep.

Highly recommend History of the Universe and its sister channels, it is incredibly calming

ZFG. He has a nice deep voice. He mostly does Zelda Ocarina of Time speed runs, but as of lately he has focused on playing Zelda randomizers.

Northernlion, specifically his non-twitch content. I also enjoy his twitch content but he goes reaction mode for it and it's not the same rhythm

StezStix Fix has a soothing channel where he fixes electronics.

Probably NileRed if he isnt handling explosives...
Some vTubers from Hololive have awesome voices and the live stream content isnt packed with interesting content

History of the entire universe

And earth

And humanity is their newest channel
