If you don’t see the voice or language you want
You can add voices to the System Voice pop-up menu by choosing Customize. If you add a voice that’s not on your Mac, it’s automatically downloaded from Apple.

- Click the checkbox beside the voice to add.
To find a voice, enter its name, country, or language in the search field.
To sample a voice, select it, then click Play.
If a yellow warning sign appears beside the selected voice, it’s downloaded when you click OK.
- Click OK.
- Choose the voice from the System Voice pop-up menu.
The voice appears in the menu when the download is complete.
