Qwen ASR · Video Generation

File TranscriptionNEW

📌 What is this：Transcribe a recorded audio file into timestamped text. Submit returns a taskId; poll for the result. On succeeded, resultUrl is the transcription file URL (JSON with text and word-level timestamps, valid 24h).

💡 When to use：Use for meeting recordings, podcasts or long audio. fun-asr-mtl supports multiple languages.

Endpoints

Usage	Method	Path
Submit task	POST	/api/cqt/generator/qwen
Query Result	GET	/api/cqt/info/qwen?id={taskId}

⏱ Recommended polling interval：All 4 models return a taskId on submit; poll by taskId until status = succeeded / failed (every 5-10s). qwen3-asr-flash is fast and usually reaches succeeded quickly.
