GitHub·medium signal

OpenBMB/VoxCPM's VoxCPM2 release is a 2B-parameter text-to-speech model trained on 2M+ hours of multilingual speech data, generating 48kHz studio-quality audio without discrete tokenization. The end-to-end diffusion autoregressive architecture (LocEnc→TSLM→RALM→LocDiT) operates entirely in AudioVAE V2 latent space, enabling voice cloning from short reference clips and brand-new voice creation from natural language descriptions. Apache-2.0 licensed with full weights and code.
