Which voice puts you under is not a preference anyone can argue you out of, and it is one of the few things about sleep audio worth choosing deliberately. Some people need a lower register to stop tracking the words; others find exactly that too close to a voice reading them the news.
These are the stories in the synthesised voices we call David from Oxford, Arthur from Ludlow, Brian from St Ives and Patrick from Block Island. What they have in common is not pitch but pacing: no performance, no characters, no leaning on a word to tell you it matters. The delivery flattens rather than dramatises, and the last third of every recording is quieter and slower than the first, on purpose, whether or not you are still awake to notice.
If none of them work, every one of them is written out in full to read if you would rather not listen at all. There are no ads and no music in any of them.
Long before plants or animals, tiny microbes changed the air and the Earth grew cold for the first time. Drift back from a Canadian lakeshore to icebergs on a silent sea.
Seventeen thousand years ago, people ground ochre by the fire and painted horses by the light of fat lamps. Spend one evening with them, from the river to the cave.
Every summer the Nile rose, left its black silt, and drew back again. Spend one evening in a village on the water, with warm bread, cloudy beer and a farmer's letters.
From far enough away, a black hole is simply something to go around. Settle into a slow orbit at the center of the galaxy and watch the starlight bend.
Five thousand years ago, the first writing was mostly receipts for barley. Spend one warm evening in Uruk, among reeds, canals and clay, as the city sleeps.
A candle, a pot of walnut-brown ink, and a man drawing the way water curls around a stone. Nothing in this room is in a hurry, and nothing is asked of you.
An evening in a walled garden, and the patient tunnel that brings its water in from the mountains. Nothing here is urgent and nothing needs remembering.
Nothing here was ever nailed, so nothing is ever finished. It has been taken apart and put back together for thirteen hundred years, and none of it needs watching tonight.
Somewhere on a cold coast tonight, a lighthouse keeper is turning a great patient light so that strangers can pass safely by. You are as watched-over as any ship out there.
Six centuries ago, a bell rang a whole valley to bed, fires were banked under clay covers, and travelers slept easy, all facing one fire. Borrow that old, whole kind of night.
