title: Keyword activated speech recognition on android
body: <p>Is it possible to use this cool voice activation feature of "google now" in you own application?</p>
  
  <p>So what I want is that the user does not have to trigger the activation by pressing a button or sth. like that.</p>
  
  <p>I'd rather like to have an automatic speech recognition activated by a keyword.
  For example: When "google now" is opened you only have to say: "google". After that command the system is listening for the actual input.</p>
  
  <p>Is this possible by using the android API? Or is there any open source library that provides this behavior?</p>
  
  <p>I know that this is possible with "open ears" but unfortunately open ears is not available for android.</p>
