Piper TTS as a windows integration

[SCBionicle]

Does anyone know of any Piper TTS based utility that allows you to install Piper as an SAPI5 or similar based application?

I have a bunch of games, and simulator plugins, that can use TTS generated voices for dialog but require them to use the windows speech synthesis API. I don't want to have to pay the data rates for Amazon Polly (I think) and Azure. Ultimately, I prefer something that works offline.

I wrote a SAPI5 TTS engine in Rust that works with piper models, you can find it at https://github.com/Lej77/windows-text-to-speech. It is a bit bare bones but it seems to works well enough for my needs. Note that I could not find any way to make it work with the Windows.Media.SpeechSynthesis.SpeechSynthesizer class and the Remarks on that page says:

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

So I suspect it is not easily fixed.
