VoxCPM2 is a nextâgeneration speech synthesis model designed to generate highly naturalâsounding audio across dozens of languages. It leverages a conditional parameterization approach that reduces memory footprint by up to 60â¯% while preserving voice fidelity. The architecture integrates a hierarchical encoder and a diffusionâbased decoder, enabling realâtime inference with latency under 150â¯ms on standard hardware. A builtâin speaker adaptation module allows users to personalize voice models with just a few seconds of audio, eliminating the need for extensive retraining. These capabilities are showcased in a comparative benchmark where VoxCPM2 outperforms prior models on MOS scores, word error rates, and multilingual consistency, as detailed in the table below.
| Metric | VoxCPM2 | Prior Model |
|---|---|---|
| MOS Score | 4.62 | 4.31 |
| Word Error Rate (%) | 5.8 | 7.4 |
| Multilingual Consistency | 92% | 84% |
