Description
StepFun StepAudio 3 Audio Generation (preview) — scripted audio from the StepAudio 3 series on POST /v1/audio/generate: define roles with a name and a voice description in plain language, write the script line by line (lines in square brackets become sound effects or background music), add an overall instruction, and get the finished audio back as bytes (mp3 by default). Voices come from the role descriptions; preset voice names are not accepted. Request fields follow StepFun's API reference. Free while StepFun's preview runs; StepFun retires the preview name when the free period ends and releases a paid version, so plan for this model ID to stop working at that point.
