Hello,
Unfortunately, despite what the piper documentation suggests, CUDA gpu support is not in the latest release version (2023.11.14-2)(or whatever prior version Calibre uses). Thus replacing the onnxruntime dlls is not sufficient in of itself. (piper.exe --help will include "--use-cuda" if it is supported)
More over, even after building the latest version from source with (I believe) CUDA support enabled, the executable crashes silently when loading the voice data. It works fine w.o CUDA, so I don't know if I built it wrong or it is just unusable.
Regardless, several github issues on piper suggest it would be slower than CPU anyway. I don't know if this would hold true for very large data like ebooks, but I can't get it working anyway.
Thanks for you help and quick response.
