const voice = createVoiceAssistant({
  // Wake word
  wakeWord: 'hey clodds',
  wakeWordSensitivity: 0.5,  // 0-1

  // Speech-to-text
  stt: {
    provider: 'whisper',  // 'whisper' | 'vosk' | 'google'

  },

  // Timeouts
  silenceTimeoutMs: 3000,
  maxRecordingMs: 30000,
});

voice.on('transcript', (result) => {
  console.log(`Final: ${result.text}`);
  console.log(`Confidence: ${result.confidence}`);
  console.log(`Duration: ${result.durationMs}ms`);
});
