Description
StepFun StepAudio 2.5 Chat — end-to-end speech understanding model: it takes audio or text in and returns text, reading paralinguistic signal such as hesitation and laughter from the waveform itself rather than from a transcript. Supports extensive persona customization covering character, speech habits, and emotional range. Audio is supplied as input_audio content parts on the chat completions endpoint. For spoken replies use a TTS model.
