uwp Speech Recognition

Question

I made a simple UWP application to test speech recognition function, But I have some error, it shows: System.UnauthorizedAccessException: 'Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))'

  public sealed partial class MainPage : Page
{

    public MainPage()
    {
        this.InitializeComponent();
    }

    SpeechRecognizer recognizer = new SpeechRecognizer();


    private async void Record_Click(object sender, RoutedEventArgs e)
    {

        var topUserLanguage = GlobalizationPreferences.Languages[0];
        var language = new Language(topUserLanguage);
        recognizer = new SpeechRecognizer(language);
        await recognizer.CompileConstraintsAsync();

        recognizer.Timeouts.InitialSilenceTimeout = TimeSpan.FromDays(1);

        var recordResult = await this.recognizer.RecognizeAsync();

        result.Text = recordResult.Text;


    }



}
