title: Any simple VAD implementation?
body: <p>I'm looking for some C/C++ code for VAD (Voice Activity Detection).</p>
  
  <p>Basically, my application is reading PCM frames from the device. I would like to know when the user is talking. I'm not looking for any speech recognition algorithm but only for voice detection.</p>
  
  <p>I would like to know when the user is talking and when he finishes:</p>
  
  <p>bool isVAD(short* pcm,size_t count);</p>
