Choose the pattern that fits your architecture

Recommended

Webhook + Audio URL

Simplest — works with every provider

Your IVR provider calls your webhook. You return an audio URL. Works out of the box with Exotel, Knowlarity, Ozonetel, and MyOperator.

// Exotel greeting applet webhook
app.get('/api/ivr/greeting', (req, res) => {
  const { CallSid, From } = req.query;
  const audioUrl = await voislabs.tts({
    text: 'नमस्ते, VoisLabs में आपका स्वागत है',
    lang: 'hi-IN',
    format: 'wav',
    sampleRate: 8000,
  });
  res.type('text/plain').send(audioUrl);
});
Real-time

WebSocket Streaming

Real-time voice for AI bots

Bidirectional audio streaming for conversational AI. Send text, receive PCM frames in real-time. Under 200ms time-to-first-byte.

// Exotel Voicebot Applet — WebSocket
ws.on('message', async (data) => {
  const stream = voislabs.stream({
    text: agentResponse,
    lang: 'ta-IN',
    format: 'pcm16',
    sampleRate: 8000,
  });
  for await (const chunk of stream) {
    ws.send(base64Encode(chunk));
  }
});
High Volume

Pre-generated Library

Zero latency for static prompts

Pre-generate IVR menus, greetings, and common prompts. Cache on CDN for instant playback. Perfect for high-volume call centers.

// Pre-generate and cache on CDN
const prompts = [
  'मुख्य मेनू के लिए 1 दबाएं',
  'कृपया प्रतीक्षा करें...',
  'धन्यवाद, आपका कॉल महत्वपूर्ण है',
];
for (const text of prompts) {
  const audio = await voislabs.generate({
    text, lang: 'hi-IN', format: 'wav',
  });
  await cdn.upload(audio, contentHash(text));
}
