Voice activity detection
RMS-based detection captures only speech and skips silence. Records short clips, time-stamps every utterance, and never asks you to tap a button in the dark.
Some of us talk in our sleep — and never know what we said. Sleep Voice Memo records the words, transcribes them on-device, and gives you a peek at the dream behind them.
Features
RMS-based detection captures only speech and skips silence. Records short clips, time-stamps every utterance, and never asks you to tap a button in the dark.
Each clip is transcribed locally using Apple Speech while you sleep. By morning, your night is written down for you — sleep talk, half-awake notes, and everything in between.
Foundation Models suggest a gentle interpretation of each fragment. What might that 3 a.m. sentence have meant? A peek behind the words.
A chronological timeline of everything you said, in order, with playback. Save favourites. Share a transcript. Delete what you don’t want.
Weekly and monthly patterns of your sleep talking, with optional sleep-stage overlay if you grant Apple Health access.
Adjust detection sensitivity from quiet mumblers to loud sleep-talkers. Choose 7–90 day retention or wipe everything with one tap.
No account. No cloud. No analytics. Audio and transcripts live in your app sandbox. Capture stops the moment you tap stop.
Optional bedtime reminder so you don't forget to start a session, and a morning notification when your night is ready to review.
