语音识别器delphi XE5

Question

我找到了一个旅行＆＃34; Android Text To Speech JNI Translation＆＃34;在论坛中。但我想将语音转换为文本，与＃34; Voice Recognize＆＃34;相同。 。 然后我在下面有几个代码：

{ TForm1.TRecognitionListener }

 constructor TForm1.TRecognitionListener.Create(AParent: TForm1);
  begin
    inherited Create;
    FParent := AParent;
  end;
 procedure TForm1.ButtonInitSpeechClick(Sender: TObject);
 var
  b : Boolean;

 begin
   b := TJSpeechRecognizer.JavaClass.isRecognitionAvailable(SharedActivityContext);
   if b then
   begin
     SpeechRecognizer :=       TJSpeechRecognizer.JavaClass.createSpeechRecognizer(SharedActivityContext);
     RecListener := TRecognitionListener.Create(self);
     RecognizerIntent :=     TJRecognizerIntent.JavaClass.getVoiceDetailsIntent(SharedActivityContext);
     RecognizerIntent.putExtra(TJRecognizerIntent.JavaClass.EXTRA_LANGUAGE_MODEL, StringToJString('en-US'));
     SpeechRecognizer.setRecognitionListener(RecListener);

  end;
end;

它有bug：＆＃34; SpeechRecognize应该来自应用程序的主要内容＆＃34; 这就是全部; Plz告诉我是什么原因？以及如何解决它。
