🤖 Moltbot TTS Integration

Using with Moltbot's Built-in TTS

Moltbot has built-in TTS support that can use ElevenLabs. Configure in ~/.moltbot/moltbot.json:

{
  "tts": {
    "enabled": true,
    "provider": "elevenlabs",
    "elevenlabs": {
      "apiKey": "your-api-key-here",
      "voice": "rachel",
      "model": "eleven_multilingual_v2"
    }
  }
}

Triggering TTS in Chat

In Moltbot conversations:

• Use /tts on to enable automatic TTS
• Use the tts tool directly for one-off speech
• Request "read this aloud" or "speak this"

Using Skill Scripts from Moltbot

# Moltbot can run these scripts directly
exec python3 /path/to/skills/elevenlabs-voices/scripts/tts.py --text "Hello" --voice rachel

⚙️ Configuration

The scripts look for API key in this order:

1. ELEVEN_API_KEY or ELEVENLABS_API_KEY environment variable
2. Moltbot config (~/.moltbot/moltbot.json → tts.elevenlabs.apiKey)
3. Skill-local .env file

Create .env file:

echo 'ELEVEN_API_KEY=your-key-here' > .env

🎛️ Voice Settings

Each voice has tuned settings for optimal output:

📝 Triggers

• "use {voice_name} voice"
• "speak as {persona}"
• "list voices"
• "voice settings"
• "generate sound effect"
• "design a voice"
