Use dictation to enter text in Pages on Mac
Place the insertion point where you want to begin dictating, or select the text you want to replace (to select placeholder text, click it).
Choose Edit > Start Dictation (from the Edit menu at the top of your screen).
If you haven’t used dictation before, follow the guided setup instructions that appear.
Tip: If dictation is set up, you can also press the Function key (fn) on your keyboard twice to start dictation.
When the microphone appears, begin speaking.
To add punctuation, speak its name (for example, comma or apostrophe).
Click Done below the microphone when you’re finished.
To change the shortcut key for dictation, or to change the language, choose Apple menu > System Preferences > Keyboard > Dictation.
To learn more about using dictation, click the desktop to switch to the Finder, choose Help > macOS Help (from the Help menu at the top of your screen), then search for “dictation.”
