UUsage with Windows.Media.SpeechSynthesis

[w0615]

Hello guys. My apologies if this is not the correct place to post this. I was wondering if it is possible to use this tts adapter on a WinUI3 app which uses Windows.Media.SpeechSynthesis to read text. When I try to get the available voices on my WinUI3 app I can only see the one core voices I have installed via the language settings menu. I assume this is because Windows.Media.SpeechSynthesis is using one core voices as the tts engine, and it appears it is not possible to switch the engine.

I was able to access the voices through my screen reader (NVDa) but I'm not sure how can I access the voices on my WinUI3 app. Thanks in advance, any help will be appreciated.

Yes, Windows.Media.SpeechSynthesis is using OneCore voices, instead of SAPI5 voices. OneCore voices seem to be Microsoft-only, as there seems to be no third-party OneCore voices yet. From the documentation:

Only Microsoft-signed voices installed on the system can be used to generate speech with a SpeechSynthesizer.

If you want to use SAPI5 voices in .net, you may try System.Speech.Synthesis.SpeechSynthesizer instead.
