macOS Dictation can be on-device in some cases, but it’s not guaranteed for every language/workflow. If you need fully offline dictation every time, use a tool that explicitly runs the recognizer locally.
How to check if your setup is offline-capable
- Turn off Wi‑Fi (or enable Airplane Mode).
- Dictate a short sentence in Notes.
- If it completes normally, your current Dictation setup likely runs on-device for that language.
- If it stalls or errors, your Dictation flow is probably using a server path for that language/settings.
How to guarantee offline dictation
- Use an on-device dictation app like Voice Type.
- Prefer a hold-to-dictate hotkey workflow to keep short dictations snappy.
- Keep mic input clean (steady distance, less background noise) to avoid re-dictation.
