A C++ inference library for running ONNX-based TTS, SVC (singing voice conversion), and SVS (singing voice synthesis) models, supporting architectures like Vits, BertVits2, SoVits, RVC, DiffusionSvc, and DiffSinger. It is callable from C, C++, and C#, and includes a fish-speech.cpp subproject rewritten with the ggml framework.

Use cases

• run tts models in c++ without python
• convert voice with rvc or so-vits-svc onnx models
• infer diffsinger singing voice synthesis models natively
• embed speech synthesis into a c# application
• run fish-speech inference with ggml

When to choose

• you need fast native C++ inference for TTS/SVC ONNX models
• you want to integrate voice conversion or synthesis into a C/C++/C# app
• you need CUDA or DirectML acceleration for speech model inference

When to avoid

• you need to train models rather than run inference
• you want a maintained GUI - the UI is no longer maintained
• you need models or architectures not in the supported list
