Dictate messages and documents on Mac
With keyboard dictation, you can dictate text anywhere you can type it. Turn it on in the Dictation pane of Keyboard preferences—your dictated utterances are sent to Apple to process your requests. A feedback window gauges your speaking volume and provides basic dictation controls. See the Apple Support article Ask Siri, Dictation & Privacy.
If you need to dictate text and control your Mac using your voice instead of a keyboard and trackpad, use Voice Control. See Control your Mac and apps using Voice Control.
Note: When Voice Control is on, you can’t use keyboard dictation.

Click On. If a prompt appears, click Enable Dictation.
If you’re asked if you want to improve Siri and Dictation, do one of the following:
Share audio recordings: Click Share Audio Recordings to allow Apple to store audio of your Siri and Dictation interactions from your Mac. Apple may review a sample of stored audio.
Don’t share audio recordings: Click Not Now.
If you change your mind later and want to share or stop sharing audio recordings, select or deselect the Improve Siri & Dictation checkbox in the Analytics & Improvements section of Privacy preferences. See Change Privacy preferences.
Note: You can delete the audio interactions (which are associated with a random identifier and less than six months old) whenever you like—see Delete Siri and Dictation history.

if available in the row of function keys, use the dictation keyboard shortcut, or choose Edit > Start Dictation.Note: Press and release
to start dictation; press and hold to ask Siri (if Siri is enabled).When the feedback window shows a microphone icon
with a fluctuating loudness indicator, or you hear the tone that signals your Mac is ready for keyboard dictation, dictate your text.Note: For best results, speak for no more than 40 seconds at a time.
To insert a punctuation mark or perform simple formatting tasks, do any of the following:
Say the name of the punctuation mark, such as “exclamation mark.”
Say “new line” (equivalent to pressing the Return key once) or “new paragraph” (equivalent to pressing the Return key twice). After you say “new line,” the dictated text appears when you’re done dictating.
For a list of the commands you can use while dictating, see Commands for dictating text.
If you set up keyboard dictation for multiple languages and want to switch languages as you dictate, click the language in the feedback window, then choose the language you want.
For information about setting up keyboard dictation for multiple languages, see “Turn on keyboard dictation,” above.
When you’re done, press the dictation keyboard shortcut, the Return key, or click Done in the feedback window.
Ambiguous text is underlined in blue. If the text is wrong, click it and select an alternative. You can also type or dictate the correct text.
