What is Feishu Edge TTS Voice Sender (Windows)?
This skill enables developers and teams to automate voice communications within the Feishu (Lark) ecosystem on Windows environments. By leveraging Microsoft's free Edge TTS engine, it generates natural-sounding speech from text and handles the complex conversion and API upload process required to display these as interactive voice bubbles rather than static file attachments. As a powerful addition to the Openclaw Skills library, it simplifies the workflow of programmatically interacting with corporate messaging platforms using neural voice technology.
Feishu Edge TTS Voice Sender (Windows) Use Cases
- Sending automated status updates via voice in Feishu groups.
- Enhancing accessibility for team notifications through audio feedback.
- Integrating with AI agents to provide verbal responses in chat interfaces.
- Developing interactive bots that respond with high-quality, human-like voice bubbles.
How Feishu Edge TTS Voice Sender (Windows) Works
- The script utilizes the edge-tts library to convert user-provided text into a high-quality MP3 audio file.
- It calls ffmpeg to transcode the MP3 into the OPUS format, which is the specific standard required for native Feishu voice messages.
- The skill interacts with the Feishu API to upload the processed OPUS file and retrieve a unique file_key.
- A final API message request is sent with msg_type set to audio, ensuring the recipient receives a playable voice bubble in their chat UI.
Feishu Edge TTS Voice Sender (Windows) Setup
First, install the required Python dependency:
pip install edge-tts
You must also have ffmpeg installed and available in your system PATH. Verify your installation with:
ffmpeg -version
Ensure your Feishu credentials (appId and appSecret) are configured in your global Openclaw configuration file. You can then run the skill using the following command structure:
python .\send_voice.py "Your Message Text" YOUR_FEISHU_OPEN_ID --voice zh-CN-XiaoxiaoNeural --config %USERPROFILE%\.openclaw\openclaw.json
Feishu Edge TTS Voice Sender (Windows) Data Schema & Taxonomy
The skill utilizes the following metadata and configuration structure to process requests within the Openclaw Skills framework:
| Parameter | Source | Description |
|---|---|---|
| appId | openclaw.json | Your Feishu application identification string. |
| appSecret | openclaw.json | Your Feishu application secret key. |
| voice | CLI Argument | The specific neural voice model (default: zh-CN-XiaoxiaoNeural). |
| open_id | CLI Argument | The unique identifier for the recipient or chat group. |
| file_key | Feishu API | A temporary key generated during the audio upload process. |
Feishu Edge TTS Voice Sender (Windows) Advanced Features
- Uses Microsoft Edge's advanced neural TTS for high-fidelity, free-to-use speech synthesis.
- Automated transcoding logic ensures compatibility with the Feishu voice bubble UI.
- Seamless integration with existing Openclaw Skills configuration files for centralized credential management.
- Direct support for the zh-CN-XiaoxiaoNeural voice for natural Chinese language delivery.
