There are OneCore voices available from Microsoft for a very great many of the world's languages.
You can add them (Windows 10 & 11) via Settings, Time & Language Pane. I'm sitting in front of Windows 11, at the moment, but I believe the "Add a language" button is available in that pane for both 10 and 11. If it's not, the analogous button or link is pretty obvious under Windows 10.

It is much easier to be critical than to be correct.
