title: Is Android speech recognition service busy?
body: <p>I use Android speech recognition service from my application.</p>
  
  <p>It turns out that when two clients attempt to send requests at the same time (say, the user started one voice search from an app, then switched to another application while the search is still active, and launched another search), the service stops working.</p>
  
  <p>Is there a way to determine that there's a voice recognition session in progress, so that I can refuse to start another one?</p>
