Voice Cloning

Replicate a target speaker's voice characteristics from a limited reference sample (few-shot or zero-shot), enabling personalized speech synthesis. Voice cloning adapts a generic TTS model to a target speaker using minimal reference audio. Zero-shot methods (VALL-E, XTTS) use a speaker encoder that extracts a voice embedding from the reference and conditions the TTS model at inference without any fine-tuning. Few-shot methods use a short adaptation step (1-30 seconds of audio) to fine-tune a base model. The key challenges are maintaining naturalness while accurately reproducing the target voice, and preventing speaker leakage from the reference into the content.
