Breakthrough Voice Cloning Technology Explained
MegaTTS3's voice cloning feature realizes three technological breakthroughs:
- Sample requirements reduced from tens of minutes to 5-10 seconds for traditional solutions
- Supports cross-language tone migration (Chinese samples generate English speech)
- Dynamic control of timbre similarity via the t_w parameter (0-3)
At the level of technical realization, the system innovatively uses:
- Pre-training acoustic feature encoder to extract deep acoustic features
- Confrontation Training Strategies to Enhance Tone Generalization
- Attention-based duration prediction module guarantees rhyme naturalness
Practical tests show that on the LibriTTS test set, the system has a tone similarity MOS of 4.2 out of 5, which is significantly better than traditional Tacotron and other architectures. It is worth noting that this feature needs to be used in conjunction with the officially provided pre-extracted latents file, which is the security boundary of the current technical solution.
