Can't change System Voice for accessibility options or announce time.

Has anyone found a workaround for when the Accessibility voice and/or System voice is stuck? Mine is on "Alex" which is alright, but I'm trying to change it to a higher khZ range so I can hear it better, and I just get the message that the voice "failed to download," or if I'm trying to change it via the Announce the Time option in the Clock settings, "Preferences Error: There was an error in Dock & Menu Bar preferences." When I deleted the Alex download, thinking it'd have to revert to the System Voice I set, it just didn't use any voice at all.

Every time I've tried to fix this, my WiFi's been on, I've restarted my computer, system preferences, and tried it both before and after the most recent software update. Doesn't have any forum results on here either. Anyone have the same thing happen to them?
