• Realtime sessions generally require WebSocket or streaming session handling in the client.

Normalized interface (asr.realtime)

Request

• model (string, optional): default qwen3-asr-flash-realtime
• language_hints (array, optional)
• format (string, optional): e.g. pcm, wav
• sample_rate (int, optional): e.g. 16000
• chunk_ms (int, optional): frame size in milliseconds

Response

Quick start

Generate a request template:

python skills/ai/audio/alicloud-ai-audio-asr-realtime/scripts/prepare_realtime_asr_request.py \
  --output output/alicloud-ai-audio-asr-realtime/request.json

Operational guidance

• Prefer 16kHz mono PCM unless your client stack requires another format.
• Keep chunks small enough for responsive partial results.
• If you only have recorded files, use skills/ai/audio/alicloud-ai-audio-asr/ instead.
