📦 Installation

No install step is required. This skill bundles a Node.js CLI and SDK (no external npm dependencies).

🧩 Key Files

scripts/tts.js - CLI entrypoint

voice-ai-tts-sdk.js - Node.js SDK used by the CLI

voices.json - Voice definitions used by the CLI

voice-ai-tts.yaml - API specification

package.json - Skill metadata for tooling

Security Notes

See SECURITY.md for the full security and privacy overview.

This skill:

Makes outbound HTTPS requests only to https://dev.voice.ai

Reads local files: voices.json

Writes audio output to the --output path (default output.mp3)

Does not execute shell commands and does not modify system configuration files

🌐 API Endpoint

The SDK and spec use https://dev.voice.ai, which is the official Voice.ai production API domain.

---

🤖 OpenClaw Integration

OpenClaw can invoke the CLI script directly if your environment exposes VOICE_AI_API_KEY. Use the /tts commands as configured by your OpenClaw installation.

---

📝 Triggers

These chat commands work with OpenClaw:

| Command | Description | |---------|-------------| | /tts | Generate speech with default voice | | /tts --voice ellie | Generate speech with specific voice | | /tts --stream | Generate with streaming mode | | /voices | List available voices |

🌍 Supported Languages

| Code | Language | |------|------------| | en | English | | es | Spanish | | fr | French | | de | German | | it | Italian | | pt | Portuguese | | pl | Polish | | ru | Russian | | nl | Dutch | | sv | Swedish | | ca | Catalan |

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:

| Parameter | Range | Default | Description | |-----------|-------|---------|-------------| | temperature | 0-2 | 1.0 | Higher = more expressive, lower = more consistent | | top_p | 0-1 | 0.8 | Controls randomness in speech generation |

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

| Format | Description | Use Case | |--------|-------------|----------| | mp3 | Standard MP3 (32kHz) | General use | | wav | Uncompressed WAV | High quality | | pcm | Raw PCM audio | Processing | | opus_48000_128 | Opus 128kbps | Streaming | | mp3_44100_192 | High-quality MP3 | Professional |

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

💰 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
