Listen: zero-shot voice cloning

20 clean reference voices that no training data contains (14 male, the rest female; EchoTTS speakers from SynDataLab-EN-Refs/echo-ref-speakers-4k-en, 44.1 kHz, chosen for the highest DNSMOS), each with its transcript, and a different sentence in each voice, synthesized by the snapshot at its operating point (32 Euler steps, guidance 5, prompt-rate duration). Single samples, seed 42, no reranking.
