Send TTS audio to Feishu as a playable audio message (msg_type=audio), not a file attachment.
Why This Skill Exists
OpenClaw's message tool sends audio as a generic file. Feishu requires a two-step API flow to display it as a playable voice message:
1. Upload with file_type=opus
2. Send with msg_type=audio
Quick Usage
bash /root/.openclaw/skills/feishu-audio/scripts/send_audio.sh
"要说的内容"
"<chat_id or user open_id>"
[voice] # optional, default: zh-CN-XiaoyiNeural
receive_id_type is always chat_id. For group chats use oc_xxx; for DMs use ou_xxx (open_id).
Common Voices
| Language | Voice |
|---|---|
| Chinese (F) | zh-CN-XiaoyiNeural (default) |
| Chinese (M) | zh-CN-YunxiNeural |
| English (F) | en-US-AriaNeural |
| English (M) | en-US-GuyNeural |
Credentials
Auto-read from /root/.openclaw/openclaw.json → channels.feishu.accounts.main. No manual setup needed in standard OpenClaw deployments.
Two-Step API Flow (for custom integrations)
# Step 1: Upload (file_type=opus is required regardless of actual format)
curl -X POST "https://open.feishu.cn/open-apis/im/v1/files"
-H "Authorization: Bearer $TOKEN"
-F "file_type=opus" -F "file_name=voice.opus" -F "[email protected]"
# → returns file_key
# Step 2: Send (msg_type=audio, NOT file)
curl -X POST "https://open.feishu.cn/open-apis/im/v1/messages?receive_id_type=chat_id"
-H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json"
-d '{"receive_id":"oc_xxx","msg_type":"audio","content":"{"file_key":"..."}"}'
Key pitfalls:
- file_type must be opus (not mp3) or upload returns 234001
- msg_type must be audio (not file) or it shows as attachment
