VoxCPM2: A Next-Generation Speech Synthesis Model=====================================================Our team is excited to introduce VoxCPM2, a cutting-edge speech synthesis model designed to produce highly natural-sounding audio across multiple languages. By leveraging a conditional parameterization approach, we’ve managed to reduce the memory footprint by up to 60% while maintaining exceptional voice fidelity.This innovative architecture integrates a hierarchical encoder and a diffusion-based decoder, enabling real-time inference with latency under 150ms on standard hardware. What’s more, our built-in speaker adaptation module allows users to personalize voice models in just a few seconds of audio, eliminating the need for extensive retraining. This means that VoxCPM2 can be tailored to individual preferences and applications, making it an incredibly versatile tool.**Comparative Benchmark Results**We’re proud to share the results of our comparative benchmark, which showcases VoxCPM2’s superiority over prior models in key metrics:* MOS scores: 4.62 (VoxCPM2) vs. 4.31 (Prior Model)* Word error rates (%): 5.8 (VoxCPM2) vs. 7.4 (Prior Model)* Multilingual consistency: 92% (VoxCPM2) vs. 84% (Prior Model)**Technical Details**

By harnessing the power of VoxCPM2, we’re confident that our customers will experience unparalleled speech synthesis capabilities.
