uwp语音识别

Question

我做了一个简单的UWP应用程序来测试语音识别功能，但是我有一些错误，它显示: System.UnauthorizedAccessException: '访问被拒绝。 (HRESULT 异常: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;


    }



}
