Nit: Was the move of friend classs.... under private intentional?
I think it should be in the same section of the dtor (which is the method that
requires the "friendship").
In this case, since this class is derived, the dtor needs to be protected, thus
the "friend " should be protected as well (not private).

Moved to protected.

 
-  virtual ~SpeechRecognizer() {}
-
   SpeechRecognitionEventListener* listener_;
   int session_id_;
 
   DISALLOW_COPY_AND_ASSIGN(SpeechRecognizer);
 };
