To make this work properly, you need to make sure you have the right speech pack installed:
The other thing, is to make sure the voices you want to use are enabled correctly.
On Windows 10 – and I have not tested this on anything else, so use it at your own risk!
You will need to run a PowerShell Script, as outlined here: https://gist.github.com/hiepxanh/8b6ad80f6d620cd3eaaaa5c1d2c660b2
add-voice.ps
$sourcePath = 'HKLM:\software\Microsoft\Speech_OneCore\Voices\Tokens' #Where the OneCore voices live
$destinationPath = 'HKLM:\SOFTWARE\Microsoft\Speech\Voices\Tokens' #For 64-bit apps
$destinationPath2 = 'HKLM:\SOFTWARE\WOW6432Node\Microsoft\SPEECH\Voices\Tokens' #For 32-bit apps
cd $destinationPath
$listVoices = Get-ChildItem $sourcePath
foreach($voice in $listVoices)
{
$source = $voice.PSPath #Get the path of this voices key
copy -Path $source -Destination $destinationPath -Recurse
copy -Path $source -Destination $destinationPath2 -Recurse
}
Do NOT run this script more than once, because you will get double entries, and who knows if it will break things.
Basically, what it will do is read the voices you have listed as installed, and then copy some registry values to enable them in third party programs, as explained here: https://www.ghacks.net/2018/08/11/unlock-all-windows-10-tts-voices-system-wide-to-get-more-of-them/
If you don’t understand Power Shell, or Regedit, then don’t be running these scripts.
Sometimes, you may get security problems, so elevating the script may also be required.
This is what happens when the aforementioned happens.
However, when it does run, our registry entries look like this originally:
Then, they look like this:
Next steps are getting a program called Balabolka.

We are going to need the console version for this task.
If you don’t have the correct voice fix installed, you will not be able to use the correct voice you want.
I wanted to have James, but I couldn’t.
But after those fixes, James worked.
I’d also suggest that if you want to script this, it may be easier to use a config file.
balcon.cfg
-f c:\balabolka\script.txt -w c:\balabolka\script.wav -n James -s -1 -p -1 -v 95 -e 300 -d d:\Dict\rules.bxd
So, when you now run balcon.exe, you get a wave file with the text file the script.
You can listen to the weather script here without any fixes. This is the Microsoft James voice.
After fixing the paragraphs and changing the voice, this is the Microsoft Catherine voice.
It doesn’t sound great at first, but it’s workable. You can also hear where the end of the line is. This can probably fixed with automation, but it’s a bit of fun.
This is where the script came from: ftp://ftp.bom.gov.au/anon/gen/fwo/IDD10111.txt
If will not be the same as this one below, as it changes regularly, but as an example, you get the idea.
As a trial run, this is the script:
