⚙️ Configuration

The scripts look for your API key in this order:

1. VOICE_AI_API_KEY environment variable
2. OpenClaw config (~/.openclaw/openclaw.json)
3. Skill-local .env file

Get your API key: Voice.ai Dashboard

Create .env file (Recommended)

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

Or export directly

export VOICE_AI_API_KEY="your-api-key"

---

🤖 OpenClaw Integration

    "voice-ai-tts": {
      "enabled": true,
      "api_key": "your-voice-ai-api-key",
      "default_voice": "ellie",
      "default_format": "mp3"
    }
  },
  "tts": {
    "skill": "voice-ai-tts",
    "voice_id": "d1bf0f33-8e0e-4fbf-acf8-45c3c6262513",

  }
}

🎙️ Available Voices

🌍 Supported Languages

Use the multilingual model for non-English languages:

const audio = await client.generateSpeech({
  text: 'Bonjour le monde!',
  voice_id: 'ellie-voice-id',
  model: 'voiceai-tts-multilingual-v1-latest',
  language: 'fr'
});

---

🎨 Voice Design

Customize voice output with these parameters:

Example:

const audio = await client.generateSpeech({
  text: 'This will sound very expressive!',
  voice_id: 'ellie-voice-id',
  temperature: 1.8,
  top_p: 0.9
});

---

📡 Streaming Mode

Generate audio with real-time streaming (recommended for long texts):

# Stream audio as it generates
node scripts/tts.js --text "This is a long story..." --voice ellie --stream

# Streaming with custom output
node scripts/tts.js --text "Chapter one..." --voice oliver --stream --output chapter1.mp3

SDK streaming:

const stream = await client.streamSpeech({
  text: 'Long text here...',
  voice_id: 'ellie-voice-id'
});

// Pipe to file
stream.pipe(fs.createWriteStream('output.mp3'));

// Or handle chunks
stream.on('data', chunk => {
  // Process audio chunk
});

🔊 Audio Formats

See voice-ai-tts-sdk.js for all format options.

🧬 Voice Cloning

Clone any voice from an audio sample:

const VoiceAI = require('./voice-ai-tts-sdk');
const client = new VoiceAI(process.env.VOICE_AI_API_KEY);

// Clone from file
const result = await client.cloneVoice({
  file: './my-voice-sample.mp3',
  name: 'My Custom Voice',
  visibility: 'PRIVATE',
  language: 'en'
});

console.log('Voice ID:', result.voice_id);
console.log('Status:', result.status);

// Wait for voice to be ready
const voice = await client.waitForVoice(result.voice_id);
console.log('Voice ready!', voice);

Requirements:

• Audio sample: 10-30 seconds recommended
• Clear speech, minimal background noise
• Supported formats: MP3, WAV, M4A

💰 Cost & Usage

Voice.ai uses a credit-based system. Check your usage:

// The SDK tracks usage via API responses
const voices = await client.listVoices();
// Check response headers for rate limit info

Tips to reduce costs:

• Use streaming for long texts (more efficient)
• Cache generated audio when possible
• Use appropriate audio quality for your use case
