I don't understand why we need two function calls on recognizer_client_ here. 
What value does that add?

+  recognizer_client_->didStartSpeech(GetHandleFromID(request_id));
 }
 
 void SpeechRecognitionDispatcher::OnSoundEnded(int request_id) {
+  recognizer_client_->didEndSpeech(GetHandleFromID(request_id));

Ditto.

   recognizer_client_->didEndSound(GetHandleFromID(request_id));
 }
