Mac dictation keyboard shortcut
Short answer: the default keyboard shortcut for Dictation on a Mac is to press the Fn (Function) key twice. You set or change it under the Apple menu › System Settings › Keyboard › Dictation, where the Shortcut pop-up menu also offers pressing the Globe key twice, pressing Control twice, or a custom combination like Option-Z. The detail worth knowing before you pick one: every built-in shortcut is a double-tap toggle that turns an always-listening session on, and the session ends on its own after about 30 seconds of silence. This page is part of the wider guide to on-device dictation for Mac. Below is how to set the shortcut, why it behaves like a toggle, how to start and stop dictation, and the push-to-talk alternative.
Set or change the shortcut
The dictation shortcut lives in one place, and changing it takes a few clicks. First make sure Dictation is turned on, then choose which keys trigger it.
- Open the Apple menu and choose System Settings.
- Click Keyboard in the sidebar, then go to Dictation and turn it on if it is off.
- Click the Shortcut pop-up menu in the Dictation settings.
- Pick one of the built-in options, or choose Customize and press your own keys, such as Option-Z.
Apple documents the same steps on its keyboard dictation support page. Here is what each option in the Shortcut menu actually does.
| Shortcut option | What it does |
|---|---|
| Press Fn (Function) Key Twice | The default. Tap the Fn key two times to start a listening session. |
| Press Globe Key Twice | Tap the Globe key twice. Useful if you already use Fn for switching input sources or emoji. |
| Press Control Twice | Tap the Control key twice. A good choice on a keyboard with no Fn or Globe key handy. |
| Customize | Press your own key combination, for example Option-Z, and that becomes the trigger. |
Notice that three of the four are a double tap of a single modifier and the fourth is a chord you press once. None of them is a key you hold. That design choice is the thing that shapes how dictation feels in practice, which is the next section.
Why it’s a double-tap toggle, not hold-to-talk
Every built-in dictation shortcut is a toggle: you tap it to switch listening on, and the session keeps running on its own until you stop it or it times out. Apple Dictation stops automatically after about 30 seconds of no speech, so a pause to gather a thought can end the session before you have finished talking. This is by design rather than a bug, and it is the most common reason people find their Mac dictation cutting off mid-sentence.
The toggle model also means you are managing state. You start a session, you talk, and then you have to remember to stop it, or it sits there listening. A hold-to-talk model removes that bookkeeping because the session is tied to the key: it exists while you hold, and it ends the moment you let go. I wrote a fuller comparison of the two models in push-to-talk against always-on dictation, since the difference is the whole reason I built Parakeety the way I did.
Start and stop dictation
There are three ways to start Apple Dictation once it is turned on. You can press the Microphone key if your keyboard has one, use the keyboard shortcut you set above, or choose Edit › Start Dictation from the menu bar. All three open the same listening session, so the shortcut is just the fastest of the three.
To stop dictation you press Escape, press the Microphone key, or press your dictation shortcut again. Because the shortcut is a toggle, pressing it a second time is how you end a session you started by hand. And if you simply stop speaking, the session ends on its own after roughly 30 seconds of silence, whether or not you meant it to. The full setup, including granting permissions the first time, is in the walkthrough on getting dictation working on a Mac. For the spoken words that control formatting and editing, see the Mac dictation commands list.
Push-to-talk instead: hold one key
Parakeety takes the opposite approach to the shortcut. Instead of tapping a key twice to toggle a session on, you hold one key, the section key (§) below Esc, while you talk, then release to stop. The session lasts exactly as long as you hold the key, so there is no toggle to remember and no 30-second silence timer to fight. When you let go, the text pastes at the cursor in whatever app you are in.
The reason this is possible is architectural. Parakeety runs NVIDIA’s Parakeet TDT 0.6B v3 model on the Apple Neural Engine, on-device, so the listening, the transcribing and the pasting all happen on your Mac with the audio never leaving the machine. Holding a key for the duration of speech is a natural fit for that local model, where Apple’s built-in shortcut was built around a different, session-based design. If you want the side-by-side, the head-to-head on Parakeety versus Apple Dictation walks through where each one fits.
FAQ
- What is the keyboard shortcut for Dictation on a Mac?
- By default you press the Fn (Function) key twice to start Apple Dictation. You set or change this under the Apple menu > System Settings > Keyboard > Dictation, using the Shortcut pop-up menu. The other built-in choices are pressing the Globe key twice, pressing Control twice, or a custom key combination such as Option-Z. There is no separate microphone-key option to set here, though a Microphone key on the keyboard, if your Mac has one, also starts dictation.
- How do I change the Dictation shortcut on a Mac?
- Open the Apple menu, choose System Settings, click Keyboard in the sidebar, then go to Dictation. Click the Shortcut pop-up menu and pick Press Fn (Function) Key Twice, Press Globe Key Twice, Press Control Twice, or Customize. If you choose Customize, press the keys you want to use, for example Option-Z, and that becomes your shortcut. The change takes effect right away with no restart.
- Why does my Mac dictation stop after a few seconds?
- Apple Dictation stops automatically after about 30 seconds with no speech. Each built-in shortcut starts an always-listening session rather than a hold-to-talk one, so if you pause to think, the silence timer runs out and the session ends. You can also stop it yourself by pressing Escape, the Microphone key, or your dictation shortcut. To avoid the cutoff entirely you would need a push-to-talk model, where the session lasts exactly as long as you hold the key.
- Is there a push-to-talk dictation shortcut on a Mac?
- Apple Dictation does not have a true hold-to-talk shortcut built in; every option is a tap-twice toggle that switches a listening session on and off. Parakeety adds real push-to-talk: you hold the section key below Esc while you talk and release to stop, and the text pastes at the cursor. The session lasts as long as you hold the key, so there is no 30-second silence cutoff to work around.
Try it
Parakeety is a Mac menu-bar app with one shortcut you hold rather than tap. Hold the section key, talk, release; your words paste at the cursor, and the audio never leaves your Mac. It runs on-device on Apple Silicon, macOS 14 and later. There is a free 7-day trial with no card required. After that it is $30 once.
