Recording & transcription
How transcription works, and how fast it is
On-device speech models give you real-time text that works offline.
Updated 2026-06-14
Your words become text as you speak. Echo Chamber transcribes on your device using Apple's Speech framework together with bundled open-source speech models, so there is no upload and no waiting on a server.
Speed depends on your device and the length of the recording, but short notes are usually ready the moment you stop, and longer recordings finish processing quickly in the background.
Models download once
The speech model downloads a single time over the internet. After that, recording and transcription keep working fully offline.
