Magnifier 'Read from here' intergration
Not so much an issue, but the natural voices do not show as options for the Magnifier accessibility tool for the 'Read from here' function. I prefer it much more than the Narrator's inbuilt navigation as it is a lot more easier to use. Currently using Windows 10.
As far as I know, Magnifier requires OneCore voices, so any third-party SAPI5 voices, including this adapter, cannot work with Magnifier. Things that also require OneCore voices instead of SAPI5 ones include UWP apps, Chromium browsers, and Electron-based apps.
Unfortunately, OneCore voices are not as open as SAPI5 voices. There's Microsoft documentation about how to make third-party SAPI5 voices, which is what my work is based on, but there's no such thing for OneCore voices. So OneCore voices are probably Microsoft-exclusive. They even state this in the OneCore voice documentation:
Only Microsoft-signed voices installed on the system can be used to generate speech with a SpeechSynthesizer.
So we can only wait until Microsoft publish an open document about how to write third-party OneCore voices, or someone find a way to "hack" into the OneCore speech system.
