🎙️ VideoAgent Audio Studio
Use when: User asks to generate speech, narrate text, create a voice-over, compose music, or produce a sound effect.
VideoAgent Audio Studio is a smart audio dispatcher. It analyzes your request and routes it to the best available model — ElevenLabs for speech and music, fal.ai for fast SFX — and returns a ready-to-use audio URL.
Quick Reference
| Request Type | Best Model | Latency |
|---|---|---|
| Narrate text / Voice-over | elevenlabs-tts-v3 | ~3s |
| Low-latency TTS (real-time) | elevenlabs-tts-turbo | <1s |
| Background music | cassetteai-music | ~15s |
| Sound effect | elevenlabs-sfx | ~5s |
| Clone a voice from audio | elevenlabs-voice-clone | ~10s |
How to Use
1. Start the AudioMind server (once per session)
bash {baseDir}/tools/start_server.sh
This starts the ElevenLabs MCP server on port 8124. The skill uses it for all audio generation.
2. Route the request
Analyze the user's request and call the appropriate tool via the MCP server:
Text-to-Speech (TTS)
When user asks to "narrate", "read aloud", "say", or "create a voice-over":
Use MCP tool: text_to_speech
text: "<the text to narrate>"
voice_id: "JBFqnCBsd6RMkjVDRZzb" # Default: "George" (professional, neutral)
model_id: "eleven_multilingual_v2" # Use "eleven_turbo_v2_5" for low latency
Music Generation
When user asks to "compose", "create background music", or "make a soundtrack":
Use MCP tool: text_to_sound_effects (via cassetteai-music on fal.ai)
prompt: "<music description, e.g. 'upbeat lo-fi hip hop, 90 seconds'>"
duration_seconds: <duration>
Sound Effect (SFX)
When user asks for a specific sound (e.g., "a door creaking", "rain on a window"):
Use MCP tool: text_to_sound_effects
text: "<sound description>"
duration_seconds: <1-22>
Voice Cloning
When user provides an audio sample and wants to clone the voice:
Use MCP tool: voice_add
name: "<voice name>"
files: ["<audio_file_url>"]
Example Conversations
User: "Voice this text for me: Welcome to our product launch"
→ Route to: text_to_speech
text: "Welcome to our product launch"
voice_id: "JBFqnCBsd6RMkjVDRZzb"
model_id: "eleven_multilingual_v2"
🎙️ Voiceover done! Listen here
User: "Generate 60 seconds of relaxing background music for a podcast"
→ Route to: cassetteai-music (fal.ai)
prompt: "relaxing lo-fi background music for a podcast, gentle piano and soft beats, 60 seconds"
duration_seconds: 60
🎵 Background music ready! Listen here
User: "Generate a sci-fi style door opening sound effect"
→ Route to: text_to_sound_effects
text: "a futuristic sci-fi door sliding open with a hydraulic hiss"
duration_seconds: 3
Setup
Required
Set ELEVENLABS_API_KEY in ~/.openclaw/openclaw.json:
{
"skills": {
"entries": {
"videoagent-audio-studio": {
"enabled": true,
"env": {
"ELEVENLABS_API_KEY": "your_elevenlabs_key_here"
}
}
}
}
}
Get your key at elevenlabs.io/app/settings/api-keys.
Optional (for fal.ai music & SFX models)
"FAL_KEY": "your_fal_key_here"
Get your key at fal.ai/dashboard/keys.
Self-Hosting the Proxy
The cli.js connects to a hosted proxy by default. If you want full control — or need to serve users in regions where vercel.app is blocked — you can deploy your own instance from the proxy/ directory.
Quick Deploy (Vercel)
cd proxy
npm install
vercel --prod
Environment Variables
Set these in your Vercel project (Dashboard → Settings → Environment Variables):
| Variable | Required For | Where to Get |
|---|---|---|
ELEVENLABS_API_KEY | TTS, SFX, Voice Clone | elevenlabs.io/app/settings/api-keys |
FAL_KEY | Music generation | fal.ai/dashboard/keys |
VALID_PRO_KEYS | (Optional) Restrict access | Comma-separated list of allowed client keys |
Point cli.js to Your Proxy
export AUDIOMIND_PROXY_URL="https://your-domain.com/api/audio"
Or set it in ~/.openclaw/openclaw.json:
{
"skills": {
"entries": {
"videoagent-audio-studio": {
"env": {
"AUDIOMIND_PROXY_URL": "https://your-domain.com/api/audio"
}
}
}
}
}
Custom Domain (Recommended)
If your users are in mainland China, bind a custom domain in Vercel Dashboard → Settings → Domains to avoid DNS issues with vercel.app.
