Remove (or hide) individual Microsoft TTS voices.

I'm using: Windows 10 Home, version 1909.

Hello, I use a program called Balabolka that can detect the Microsoft voices installed in your system and read texts to you using those TTS voices.

I have installed the voice packages for several languages through: Settings/Time & Language/Speech/Add voices.

Many of these voices remain hidden to other applications. But, I was able to make the necessary changes for individual voices to be detected (in this case by Balabolka) using something along the lines of: Unlock all Windows 10 TTS voices system-wide to get more of them - gHacks Tech News

PROBLEM:
Now I wonder if it would be possible to delete, or at least hide from other apps, some of the Microsoft voices I don't use. For instance: keep Microsoft Zira but delete Microsoft David (both US English, https://support.microsoft.com/en-us/...guages-voices/) and so on.

I created a restore point and I tried to modify or delete those voices using regedit as an administrator (and also in safe mode) but it gave me an error about permissions. I couldn't gain control of the entries, either.

Does anyone know a way of accomplishing this? Thank you!

I think you can do also so this via Registry Editor I guess.
