Model Studio Qwen ASR (Non-Realtime)

Validation

bash

mkdir -p output/alicloud-ai-audio-asr
python -m py_compile skills/ai/audio/alicloud-ai-audio-asr/scripts/transcribe_audio.py && echo "py_compile_ok" > output/alicloud-ai-audio-asr/validate.txt

Pass criteria: command exits 0 and output/alicloud-ai-audio-asr/validate.txt is generated.

Output And Evidence

• Store transcripts and API responses under output/alicloud-ai-audio-asr/.
• Keep one command log or sample response per run.

Use Qwen ASR for recorded audio transcription (non-realtime), including short audio sync calls and long audio async jobs.

Critical model names

Use one of these exact model strings:

• qwen3-asr-flash
• qwen-audio-asr
• qwen3-asr-flash-filetrans

Selection guidance:

• Use qwen3-asr-flash or qwen-audio-asr for short/normal recordings (sync).
• Use qwen3-asr-flash-filetrans for long-file transcription (async task workflow).

Prerequisites

• Install SDK dependencies (script uses Python stdlib only):

bash

python3 -m venv .venv
. .venv/bin/activate

• Set DASHSCOPE_API_KEY in environment, or add dashscope_api_key to ~/.alibabacloud/credentials.

Normalized interface (asr.transcribe)

Request

• audio (string, required): public URL or local file path.
• model (string, optional): default qwen3-asr-flash.
• language_hints (array, optional): e.g. zh, en.
• sample_rate (number, optional)
• vocabulary_id (string, optional)
• disfluency_removal_enabled (bool, optional)
• timestamp_granularities (array, optional): e.g. sentence.
• async (bool, optional): default false for sync models, true for qwen3-asr-flash-filetrans.

Response

• text (string): normalized transcript text.
• task_id (string, optional): present for async submission.
• status (string): SUCCEEDED or submission status.
• raw (object): original API response.

Quick start (official HTTP API)

Sync transcription (OpenAI-compatible protocol):

bash

curl -sS --location 'https://dashscope.aliyuncs.com/compatible-mode/v1/chat/completions' \
  --header "Authorization: Bearer $DASHSCOPE_API_KEY" \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "qwen3-asr-flash",
    "messages": [
      {
        "role": "user",
        "content": [
          {
            "type": "input_audio",
            "input_audio": {
              "data": "https://dashscope.oss-cn-beijing.aliyuncs.com/audios/welcome.mp3"
            }
          }
        ]
      }
    ],
    "stream": false,
    "asr_options": {
      "enable_itn": false
    }
  }'

Async long-file transcription (DashScope protocol):

bash

curl -sS --location 'https://dashscope.aliyuncs.com/api/v1/services/audio/asr/transcription' \
  --header "Authorization: Bearer $DASHSCOPE_API_KEY" \
  --header 'X-DashScope-Async: enable' \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "qwen3-asr-flash-filetrans",
    "input": {
      "file_url": "https://dashscope.oss-cn-beijing.aliyuncs.com/audios/welcome.mp3"
    }
  }'

Poll task result:

bash

curl -sS --location "https://dashscope.aliyuncs.com/api/v1/tasks/<task_id>" \
  --header "Authorization: Bearer $DASHSCOPE_API_KEY"

Local helper script

Use the bundled script for URL/local-file input and optional async polling:

bash

python skills/ai/audio/alicloud-ai-audio-asr/scripts/transcribe_audio.py \
  --audio "https://dashscope.oss-cn-beijing.aliyuncs.com/audios/welcome.mp3" \
  --model qwen3-asr-flash \
  --language-hints zh,en \
  --print-response

Long-file mode:

bash

python skills/ai/audio/alicloud-ai-audio-asr/scripts/transcribe_audio.py \
  --audio "https://dashscope.oss-cn-beijing.aliyuncs.com/audios/welcome.mp3" \
  --model qwen3-asr-flash-filetrans \
  --async \
  --wait

Operational guidance

• For local files, use input_audio.data (data URI) when direct URL is unavailable.
• Keep language_hints minimal to reduce recognition ambiguity.
• For async tasks, use 5-20s polling interval with max retry guard.
• Save normalized outputs under output/alicloud-ai-audio-asr/transcripts/.

Output location

• Default output: output/alicloud-ai-audio-asr/transcripts/
• Override base dir with OUTPUT_DIR.

Workflow

1. Confirm user intent, region, identifiers, and whether the operation is read-only or mutating.
2. Run one minimal read-only query first to verify connectivity and permissions.
3. Execute the target operation with explicit parameters and bounded scope.
4. Verify results and save output/evidence files.
