  • A camera built into the dashboard also tracks your lip movements to improve the accuracy of speech recognition.
  • A voice analyzer then looks for signs of tiredness by checking to see if the answer matches your profile. Slow responses and lack of attention are signs of fatigue.

  • If your response is slow or doesn’t make sense, the voice analyzer assumes you are dropping off and acts to get your attention.
