Open-source 48kHz TTS with voice design and cloning
VoxCPM2 is a 2B open-source TTS model with 30-language support, 48kHz output, voice design from text alone, controllable voice cloning, and real-time streaming fast enough for production voice workflows.
VoxCPM2 is the next-generation open-source audio model from the @MiniCPM family, and it perfectly continues their signature trait of incredible "capability density" — packing all of these features into a model that is only 2B parameters!
Despite its highly compact size, the feature set it brings to the table is quite rare for an open-source release:
Voice Design: Instead of hunting for the perfect reference audio to clone, you can just prompt the model directly (e.g., (A young woman, gentle and sweet voice) Hello world.). It generates a completely novel voice on the fly.
Native 48kHz Output: It has a built-in super-resolution VAE, meaning no external upsamplers are needed to get studio-quality audio.
Controllable Voice Cloning: You can clone a voice from a short clip, but still steer the emotion, pacing, and style using text prompts.
Production-Ready: It hits an RTF of ~0.13 for real-time streaming and is fully open-source under the Apache-2.0 license.
It is incredibly refreshing to see this level of controllable, high-fidelity audio hit the open-source ecosystem in such a lightweight package.
