Feishu Voice Bot

Send native voice bubbles via Feishu using edge-tts + ffmpeg. Converts text to OGG/Opus audio and sends as a playable blue voice bubble. Use when: (1) User sends a voice message and expects voice reply. (2) User says "语音回复" or "用语音". (3) Any TTS/voice output to Feishu. Requires: edge-tts skill (scripts/tts-converter.js), ffmpeg, message tool with channel=feishu.

Feishu Voice Bubble

Send native voice bubbles (蓝色可播放气泡) via Feishu using bot identity.

Workflow

text → edge-tts (mp3) → ffmpeg (ogg/opus) → message tool (media=) → 原生气泡

Quick Usage

# One-liner via the helper script
node scripts/voice-bubble.mjs "你好陛下" --voice zh-CN-XiaoxiaoNeural

Or use the message tool directly after generating the audio:

# Step 1: Generate
cd ~/.openclaw/workspace/skills/edge-tts/scripts
node tts-converter.js "文本" --voice zh-CN-XiaoxiaoNeural --output /tmp/voice.mp3

# Step 2: Convert
ffmpeg -i /tmp/voice.mp3 -c:a libopus -b:a 32k /tmp/voice.ogg -y

# Step 3: Send via message tool
message(action=send, channel=feishu, target=<open_id_or_chat_id>, media=/tmp/voice.ogg)

Notes

• 无需用户 OAuth — 机器人身份 + message tool + media= 即可发送原生气泡
• 格式 — 飞书要求 OGG/Opus 格式，edge-tts 输出 MP3，需 ffmpeg 转换
• 临时文件 — 生成的音频存于 /tmp/，不会自动清理
• 中文默认 — 未指定 voice 时使用 zh-CN-XiaoxiaoNeural
