Dictate your email in Outlook for Mac

By Office Feature PM on May 11, 2020

Hi! I’m James Spotanski, a Program Manager bringing Speech features to Office. I’m excited to share that you will be able to dictate your email soon! The Dictate feature is coming to Outlook for Mac. It’s now available to Insiders Fast and will make its way to Insiders Slow in the coming weeks.


  • A microphone.
  • An Insiders build of Office for Mac 16.37 (20042602) or later.
  • Signed in to a Microsoft 365 account.
  • A stable Internet connection.

For the best results, we recommend using an external microphone or headset. This is the most noteworthy thing you can do to improve the accuracy of dictation!


  • Make sure your microphone-enabled device is on.

If you have problems with your microphone-enabled device, check the sound input settings in System Preferences or dictation troubleshooting instructions.

Dictate your email

1. Create an email or reply to an existing conversation.

2. We don’t currently auto-detect the language you’re speaking. So, click the down arrow on the Dictate button and select the language you want in the list.

3. Click the Dictate button on the Message tab of the ribbon and wait for the red dot to appear to the right of the microphone. You can also use the keyboard shortcut Opt+F1.

dictate your email4. Start talking and notice that the spoken words appear on your screen. If you see a mistake, move your cursor to fix it and move it back to continue dictating. You don’t need to toggle off the Dictate button while making corrections.

5. When you’re done, click the Dictate button.

Note: You can also use the Dictate feature in the new Outlook for Mac by following the procedure above or clicking the Dictate button in the formatting tools displayed in any messages.

Tips and tricks

  • When dictating:
    • Speak clearly and conversationally, but feel free to pause in between thoughts. The feature will automatically pause after 20 seconds of silence.
    • Add punctuation by saying the name of the punctuation mark you want to add out loud.
      • Period
      • Comma
      • Question mark
      • Exclamation point/mark
      • New line
      • Semicolon

      • Open quote(s)
      • Close quote(s)
  • This feature is powered by the Microsoft Azure Speech Services and built-in directly into Outlook.
