Summary
OpenBMB released VoxCPM2, a 2B-parameter tokenizer-free TTS system built on a diffusion autoregressive architecture and MiniCPM-4 backbone, supporting 30 languages with voice design from natural-language descriptions and controllable voice cloning from short reference clips. It outputs 48kHz studio-quality audio via an AudioVAE V2 asymmetric encode/decode with built-in super-resolution, achieves a real-time factor of ~0.13 when accelerated by vLLM-Omni's PagedAttention, and is fully open-sourced under Apache-2.0 for commercial use.
