Step-Audio-EditX

Apache-2.0

Re-edit the emotion or style of audio you already generated

Step-Audio-EditX from StepFun AI is built around iterative editing rather than one-shot generation: you can take audio you already made and regenerate just the emotion, style, or a paralinguistic detail (breathing, laughter) without touching the words or re-cloning the voice. It tops recent open-model Elo rankings for emotion control, and also handles Cantonese and Sichuanese dialects alongside standard Mandarin and English.
