If you’ve called out, “Hey Siri” to your iPhone before, you know the joy of this Star Trek-style technology. You don’t even need to hold the Home button down. Sure, your iPhone needs to be plugged in, but it’s a pretty neat party trick.
Excitingly, you can do something similar on your Mac: activating dictation with a voice command. The next time you get a great idea and need to document it, you can just call to your Mac and dictate it right then. No pen, no paper, no walking all the way to your keyboard.
Set up voice command on your Mac
Launch System Preferences, either from your Dock or Apple Menu, and then click on Dictation & Speech. When you enable Dictation by clicking the On radio button the first time, you’ll be asked if you want to enable Enhanced Dictation, which is a 1.2 G download. Go ahead and do just that: it will allow you to dictate when offline as well as allow for a more natural speaking pattern.
Next, back out to the main System Preferences screen and click on Accessibility. Scroll to the bottom of the list in the left-hand pane and click on Dictation. Then, click on the Dictation Commands button to the right, and then click to check the Enable advanced commands checkbox.
Click the Done button, and then check the Enable the dictation keyword phrase checkbox. Enter the phrase you want your Mac to listen for to start dictation. Something pithy, like “Hey, Macintosh,” or (if you’re feeling sassy) “Hey, Mr. MacPants.”
Enable “Play sound when command is recognized” so you can hear if your Mac is ready to dictate. Otherwise, you’ll be chatting away to your computer and it won’t be listening. Insert marital joke here.
You probably also want to enable “Mute audio output while dictating,” so that any sounds from your Mac won’t interfere with your dictation. You can close System preferences, now.
Tell your Mac what to type
Now all you need to do is to test it out. Open something like TextEdit and then call out your command phrase. The little dictation window will appear, and the mic icon within it will have an animated level on it. Simply speak what you want it to type. There are a ton of other actions you can employ, too, like Select All, Undo That, Uppercase That, and more – all found in the Dictation Commands button in the Accessibility pane as above.
Dictation should work wherever you can type, including Safari, Reminders, Pages, and the like. If your Mac has trouble reacting to your voice command, try a simpler phrase, or just hit the Function key twice to bring up Dictation. Hooray!
