何が起きたか: Baseten published a fine-tuning recipe for Qwen3-TTS that improves voice cloning quality by training on larger speaker-specific datasets rather than relying on zero-shot cloning alone.
なぜ重要か: Matters for engineers building voice products who need better expressiveness and consistency than instant cloning provides, especially with limited reference audio budgets.
注意点: Fine-tuning on 1.5 hours of audio showed perceptual improvements in expressiveness but did not materially beat zero-shot on similarity metrics or quality scores, suggesting diminishing returns on smaller datasets.
