Recognition Listener not listen

Question

I created this service to listen in the background, career service, but do not know if the listener listen or not, yet only show in the Logcat message when the service starts ... I have read others questions in stackoberflow but anything run in my case.

public class ServicioVoz extends RecognitionService {

private SpeechRecognizer sr;
private VoiceResultsListener vrl;
public Principal principal;

@Override
public void onCreate() {
    super.onCreate();
    Log.i("Dins del servei", "Arrancat");
}

@Override
public void onDestroy() {
    super.onDestroy();
    Log.i("SimpleVoiceService", "Service stopped");
}

@Override
protected void onCancel(Callback listener) {
    sr.cancel();
}

@Override
protected void onStartListening(Intent recognizerIntent, Callback listener) {
    Log.e("escoltant", "________________________________");
    sr.setRecognitionListener(new VoiceResultsListener(listener));
    sr.startListening(recognizerIntent);
}

@Override
protected void onStopListening(Callback listener) {
    sr.stopListening();
    Log.e("Atura d'escoltar", "________________________________");
}
