Description

I am attempting to add more voices to my local Piper TTS. I found this repo that contains several pre-trained models. It seems that I can convert from the downloaded RVC Model to ONNX, however, Piper also requires a .onnx.json file to run. Is there a tool to create such a file? Or perhaps another method?

I have also tried to simply convert onnx to json but it seems that the .onnx.json file needs to be in a specific format.

Research direction

Start by examining how the downloaded RVC models are converted to ONNX and compare the resulting artifacts with Piper's required .onnx.json format. The issue names no repository files or tests; done would be a documented, working conversion path or a clear explanation of whether such an export is supported.
