qwen-audio-lab

Hybrid text-to-speech, reusable voice cloning, and narrated audio generation for macOS plus Aliyun Qwen. Use when the user wants to convert text into speech, clone and reuse a voice from a reference recording, generate narration files from plain text or text files, or create PPT speaker-note voiceovers.

Use this skill for text-to-speech on macOS or with Aliyun Qwen.

Choose the backend

• Use mac-say for fast local playback, notifications, and low-friction speech on a Mac.
• Use qwen-tts when the user wants better naturalness, reusable output files, custom voices, or voice cloning.
• If DASHSCOPE_API_KEY is missing, fall back to mac-say for local playback.

Environment

• DASHSCOPE_API_KEY: required for Qwen synthesis and voice cloning.
• QWEN_AUDIO_REGION: optional, cn (default) or intl.
• QWEN_AUDIO_OUTPUT_DIR: optional directory for generated audio files. Defaults to ~/.openclaw/data/qwen-audio-lab/output.
• QWEN_AUDIO_STATE_DIR: optional directory for local state such as remembered voices. Defaults to ~/.openclaw/data/qwen-audio-lab/state.

Commands

Run all commands through:

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py <command> [...]

Preferred high-level commands

Use these first for most user-facing narration tasks:

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py narrate-text --text "这是要转成语音的正文"
python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py narrate-file --text-file /path/to/script.txt
python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py narrate-ppt --ppt /path/to/file.pptx

Use the older commands only when you specifically want the legacy workflow names. Generated audio and remembered voice state now default to ~/.openclaw/data/qwen-audio-lab/ instead of the skill folder.

Local macOS speech

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py mac-say \
  --text "开会了，别忘了带电脑" \
  --voice Tingting

Qwen TTS from inline text

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py qwen-tts \
  --text "你好，我是你的语音助手。" \
  --voice Cherry \
  --model qwen3-tts-flash \
  --language-type Chinese \
  --download

Qwen TTS from a text file

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py qwen-tts \
  --text-file /path/to/script.txt \
  --voice Cherry \
  --download

Qwen TTS from stdin

bash

cat /path/to/script.txt | python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py qwen-tts \
  --stdin \
  --voice Cherry \
  --download

Clone a voice

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py clone-voice \
  --audio /path/to/reference.mp3 \
  --name claw-voice-01 \
  --target-model qwen3-tts-vc-2026-01-22

• Keep the cloning target-model aligned with the synthesis model family.
• Use a clean speech sample with minimal background noise.
• Ask before cloning a third party voice when consent is unclear.

Design a voice from a text prompt

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py design-voice \
  --prompt "沉稳的中年男性播音员，音色低沉浑厚，适合纪录片旁白。" \
  --name doc-voice-01 \
  --target-model qwen3-tts-vd-2026-01-26 \
  --preview-format wav

Legacy command: reuse the latest cloned voice

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py speak-last-cloned \
  --text "你好，这是我的声音测试。" \
  --download

High-level narration from any text source

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py narrate-text \
  --text "这是要转成语音的正文" \
  --output narration.wav

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py narrate-file \
  --text-file /path/to/script.txt

• Default voice source is last-cloned.
• Use --voice-source last-designed to use the latest designed voice instead.
• Use --voice and optionally --model to force a specific voice id and synthesis model.

Legacy command: narrate PPT speaker notes with the latest cloned voice

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py ppt-own-voice   --ppt "/path/to/file.pptx"

High-level PPT narration

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py narrate-ppt   --ppt "/path/to/file.pptx"

• Default voice source is last-cloned.
• Use --voice-source last-designed to switch to the latest designed voice.
• Use --voice and optionally --model to force a specific voice id and synthesis model.
• Keep ppt-own-voice as the backward-compatible alias for the original workflow.

Inspect or manage remembered voices

bash

python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py list-voices
python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py show-last-voice --kind cloned
python3 ~/.openclaw/skills/qwen-audio-lab/scripts/qwen_audio.py delete-voice --voice claw-voice-01

Workflow rules

• Reuse an existing cloned voice before asking for a new sample.
• Ask for a reference recording if the user wants their own voice and no cloned voice exists yet.
• Prefer the narrate-* commands as the primary high-level interface for narration tasks.
• Keep speak-last-cloned and ppt-own-voice for backward compatibility with older workflows.
• Keep only final outputs by default after segmented synthesis unless the user explicitly asks to keep fragments.
