I tried using Siri on Mac after my upgrade to macOS Sierra, and it works as expected, even I’m still using some basic commands. It’s just like they way I talk to Siri on my iPhone and iPad. Asking Siri is simple, just hit the Siri button on the menu bar, and send your command.

But, can we call Siri from a keyboard shortcut or even dictation? Yes, we can.

By default, Siri can be called by holding Command and Space. Just press the Command and Space on your keyboard. But, we can override this setup by making our own keyboard shortcut. Go to System Preferences, choose Siri and there is an option to change they Keyboard Shortcut value.

You can choose one of the option or create a new shortcut by choosing “Customize”. Right now, I use Control and Space as my custom keyboard shortcut. But, what about calling Siri using dictation command? These are some simple steps:

1. Go to Dictation menu tab under Keyboard settings from your System Preferences. Turn the Dictation “On” and tick the “Use Enhanced Dictation” option.
2. Go back to System Preference screen and choose Accessibility menu. From this screen, go to Dictation menu. Tick on “Enable the dictation keyword phrase:” and I type “Hey” (without quotes) because I want to use “Hey Siri!” as my dictation command. After this, hit the “Dictation Commands…” menu button on the same window.
3. Tick on “Enable advanced command” option so that we can add a new command by clicking on the “plus” button. Here are my current option values:
   • When I say: Siri
   • While using: Any Application
   • Perform: Press Keyboard Shortcut…
4. In the previous step, I choose Control and Space as my custom keyboard shortcut (to call Siri). So, I do the same here. Click “Done” to end this setup.

After the setup, I can now have Siri available both from keyboard shortcut or dictation. Look ma, hands free!
