Every night, millions of people fall asleep to our voices. It’s fair to wonder whose voices they are.
The short answer: real people’s. Every episode of every show we make is narrated by a human being, written and edited by human writers, and mixed by a human audio engineer. We do use AI tools in a few specific places away from the storytelling — and because you’re trusting us with the most vulnerable hour of your day, we’d rather tell you exactly where than leave you guessing.
The voices are human — all of them
Every narrator on every Slumber Studios show is a real person — most of them based in and around London, which is why so many listeners fall asleep to British voices:
- Tom Jones hosts Get Sleepy, Snuggle, and Deep Sleep Sounds — with rotating casts of gentle guest narrators joining him on Get Sleepy and Snuggle.
- Simon Mattacks is the primary narrator of Sleepy History, alongside a rotating cast of guest narrators.
- Elizabeth Grace reads every book on The Sleepy Bookshelf.
- Andrew Bond hosts and narrates Send Me To Sleep.
We have never used an AI voice on any show, and we don’t plan to start. The thing listeners tell us works — the unhurried pacing, the warmth, the sense that someone is genuinely reading to you — is a performance. It’s the whole craft, and it doesn’t survive being synthesized.
The writing is human
Our stories are researched, written, and edited by people: our in-house team and the freelance writers we commission. Every script passes through human editors before it’s recorded, because “accurate but boring in the best way” is a surprisingly hard editorial standard to hit.
One thing we want to be straight about: on rare occasions, we’ve discovered after publication that a commissioned freelance writer leaned on AI tools without telling us. We weren’t happy about it, and we’ve since tightened how we commission and review scripts to catch it. We think honesty about the rare exception is worth more than a tidy claim of perfection.
The sound is human
A human audio engineer mixes every episode — the narration levels, the music beds, the long gentle fades that carry you from “listening” to “asleep.”
Most of our music is composed and performed by real artists — you can meet them, and hear their work, on our music pages. Some pieces are made with the help of AI tools; the majority are not.
Where we do use AI
We use AI where it doesn’t touch the storytelling:
- Artwork. Much of our episode and show art is AI-generated or AI-assisted, guided and selected by our team. Some of it is still made entirely by hand.
- This website. The copy you’re reading was drafted with AI tools and reviewed by our team.
- Our apps. The code behind our apps is mostly written by our developers, with AI assistance on some recent work.
What we don’t use it for: voices, ever; and the writing, editing, and sound of our shows, which remain human work.
Why we’re telling you this
Falling asleep to something is an act of trust. You’re at your least guarded, and you deserve to know there’s a person on the other side of the microphone — someone who read the story, thought about the pacing, and cared whether you drifted off by the second act.
If you ever have a question about how something we made was produced, ask us directly. A real person will answer that, too.
