Feishu Voice Loop

Provide a reusable three-step voice loop for OpenClaw:

1. 1. accept text or voice input
2. generate speech with OpenAI TTS
3. return the audio to Feishu or a web player

When the input is voice, transcribe it to text first, then continue through the same output pipeline.

Quick start

Prerequisites:

• - OPENAI_API_KEY is set for TTS
• Feishu app credentials exist in ~/.openclaw/openclaw.json under channels.feishu.appId/appSecret, or are passed explicitly
• INLINECODE3 and ffprobe are installed and available
• local audio transcription is configured in ~/.openclaw/openclaw.json under INLINECODE6

Main scripts:

• - INLINECODE7
• INLINECODE8

Tasks

1. Transcribe voice input

Use this when you have a local .ogg, .opus, .wav, or similar file and want text.

CODEBLOCK0

This script reuses the existing Whisper CLI configuration from ~/.openclaw/openclaw.json.

2. Generate and send voice output

Use this when you already have text and want to send a Feishu voice message.

CODEBLOCK1

The script will:

1. 1. call OpenAI INLINECODE13
2. save WAV audio temporarily
3. convert to Feishu-friendly Opus via INLINECODE14
4. upload the file to Feishu
5. send an audio message to the target INLINECODE16

3. Run the full voice loop

Use this skill when the goal is a reusable voice interaction pipeline:

1. 1. transcribe input audio to text
2. decide or generate the reply text
3. synthesize reply audio with OpenAI TTS
4. send the reply back to Feishu

Read references/input-output-workflow.md when building or explaining the end-to-end loop.

Default output style

Default preset is stored in references/presets.md.

Unless the user asks otherwise, use:

• - model: INLINECODE19
• voice: INLINECODE20
• default style: 年轻日系男声感、温柔里带一点撩、贴耳边私聊感、自然、不播音腔

When the user asks for a different flavor, either:

• - pass a custom INLINECODE21
• or adapt one of the presets in INLINECODE22

Handle failures

Common failure cases:

• - Missing OPENAI_API_KEY → ask for API key / env setup
• HTTP 429 from OpenAI → billing or quota issue
• missing Feishu app credentials → configure INLINECODE24
• missing ffmpeg or ffprobe → install locally before retrying
• missing transcription model config → configure INLINECODE27

When OpenAI billing is not enabled, say so directly instead of pretending the voice was generated.

Packaging and sharing

Package with:

CODEBLOCK2

The resulting .skill file can be shared or uploaded wherever the user distributes skills.
