Offline Speech to Text on Mac: Dictate Without Internet or the Cloud

Offline speech to text on a Mac means your voice is turned into text on the Mac itself, with no internet connection and no audio sent to a server. It works on a plane, on a train, and on locked-down work networks, and your words never leave the device.

Not every dictation tool works this way. Here is how to check what your Mac does today, and which options run fully offline.

Why offline matters

• Privacy. If your audio never leaves the Mac, no company stores it, reviews it or trains on it. That matters for patient notes, client work, contracts and personal writing.
• It works anywhere. No Wi-Fi, weak hotel internet, airplane mode: offline tools do not care.
• Speed. No upload and no waiting for a server. Words can appear as you speak.
• No usage fees. Cloud transcription is often billed per minute. Local tools run on hardware you already own.

Does Mac Dictation work offline?

It depends on your Mac and the language you speak.

1. Open Apple menu > System Settings > Keyboard.
2. Look at the text under the Dictation switch.

That text says whether your speech is processed on your Mac or sent to Apple's servers. If it is sent to servers, built-in Dictation needs internet for that language.

There is also a separate setting for sharing recordings with Apple: System Settings > Privacy & Security > Analytics & Improvements > Improve Siri & Dictation. Turn it off if you do not want Apple to store and review samples of your audio.

The 10-second offline test

You can check any dictation app the same way:

1. Turn off Wi-Fi (and unplug the network cable if you use one).
2. Click in a text field and start dictating.
3. If text still appears, the tool runs offline.

Try it with long sentences and with each language you use. Some tools work offline for one language but not another.

How to get voice to text without internet on Mac

Set this up while you are still online, then test it before you travel. These steps are for built-in Dictation on macOS 27. Menu names can differ on older versions.

1. Open Apple menu > System Settings, then click Keyboard in the sidebar. You may need to scroll down.
2. Go to Dictation and turn it on. Click Enable if your Mac asks.
3. Read the text under the Dictation switch. You want it to say your speech is processed on your device.
4. Click Edit next to Languages and add each language you need.
5. Turn off Wi-Fi and dictate a few sentences in each language.

Do step 5 at home, not at the airport. Apple's Dictation page does not promise offline use, and it does not list what works without internet. Apple's Keyboard page mentions languages you have downloaded, but it does not say when that happens. Only your own test gives you a sure answer.

If a language fails the test, or the text says your speech goes to Apple, use an app that runs on your Mac. Install it and run the same test while you still have internet. A dictation app has to be on your Mac before you can use it offline.

Your offline options on Mac

Built-in Dictation

Free and already on your Mac. Where your Mac processes your language on the device, it is a good choice for short messages. It stops after 30 seconds of silence, and on-device support depends on your Mac and language. See how to dictate on Mac for setup.

Open-source Whisper tools

OpenAI released its Whisper speech model as open source, and developers have built free local versions such as whisper.cpp. They are accurate and fully offline. Some are command-line tools or simple file transcribers. Others, such as MacWhisper, Superwhisper and VoiceInk, wrap Whisper in a Mac app. Our guide to Whisper apps for Mac compares them.

TalkFlowy

TalkFlowy is a Mac app built for offline dictation in every app. It runs speech recognition on local AI models on your Mac, so it works 100% offline and your voice is never sent to a server.

• Press a system-wide shortcut, speak, and your words appear live, word by word.
• AutoPaste puts the text into whatever app you are using: Slack, Gmail, Outlook, Notion, Word, Google Docs, VS Code, Cursor, terminals and browsers. It is also copied to the clipboard.
• 50+ languages with one-click switching.
• Transcribes audio and video files locally too. See how to transcribe audio to text on Mac.
• One-time lifetime license, no subscription and no per-minute fees. There is a free trial with no credit card.

It needs an Apple Silicon Mac (M1 or newer) with macOS 14.6 or later. It does not run on Intel Macs.

Who needs offline dictation most

• Healthcare. Clinical notes contain sensitive patient details. See private, offline dictation for healthcare professionals.
• Legal. Client conversations are confidential. See private legal dictation on Mac.
• Developers. Prompts and docs often include internal code and client names. See voice dictation for developers.
• Travelers and remote workers. Anyone who writes on planes, trains or bad hotel Wi-Fi.

Quick checklist

1. Check the text under Keyboard > Dictation to see where your speech goes today.
2. Turn off Improve Siri & Dictation if you do not want recordings shared.
3. Run the Wi-Fi off test with every tool you rely on.
4. For private, offline dictation in every app, try TalkFlowy free.
