Change the voice your Mac uses to speak text
You can change the voice your Mac uses to speak text in a window or in alert messages.
Choose a voice

Add a new voice
You can add voices to the System Voice pop-up menu. If you add a voice that’s not on your Mac, it’s automatically downloaded from Apple (you must be connected to the internet).
On your Mac, choose Apple menu
Click the System Voice pop-up menu, then choose Customize.
Select the checkbox beside the voices you want to add.
To find a voice, enter its name, country or region, or language in the search field.
To sample a voice, select it, then click Play.
When you’re done selecting voices, click OK.
Click the System Voice pop-up menu, then choose a voice you added.
Voices that are downloaded aren’t available until the download is complete.
Delete a downloaded voice
You can delete a voice that you downloaded to your Mac.
On your Mac, choose Apple menu

Deselect the checkbox for the voice you want to delete.
Click OK, then click Delete.
If your computer is speaking and you want it to stop, try one of these solutions:
In the menu bar of the app you’re using, choose Edit > Speech > Stop Speaking.
If VoiceOver (the built-in screen reader) is speaking, press Command-F5 to turn it off.
