StepAudio 3 ASR Max

StepAudio 3 ASR Max combines acoustic modeling with language-model context. The model guide covers Chinese, English, dialects, mixed-language speech and specialist terms.

Use context to resolve similar sounds

The model is designed to use domain knowledge and surrounding meaning for names and technical words. This differs from a general audio conversation model that produces a free-form reply.StepFun stepaudio-3-asr guide

Review critical names in the result

Practical guidance. Context can improve a transcription, but it can also make an incorrect word look plausible. Compare proper names, numbers and specialist terms with the original recording. Use a representative set of your domain's audio for evaluation.
