我正在开发一个新应用程序，我在其中使用 windows phone 8 的语音识别功能。但是，我收到以下异常：

HRESULT 异常：0x800455BC

在 System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务） 在 System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification（任务任务） 在 System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() 在 ExcerciseMod7Voice.MainPage.d__4.MoveNext ()

这是我尝试使用的代码：

 private async void btnSpeak_Click(object sender, RoutedEventArgs e)
 {
         var recognizer = new SpeechRecognizerUI();
         recognizer.Settings.ShowConfirmation = true;
         recognizer.Settings.ReadoutEnabled = false;

         try
         {
             var result = await recognizer.RecognizeWithUIAsync();
             if (result.ResultStatus == SpeechRecognitionUIStatus.Succeeded)
             {
                 MessageBox.Show(result.RecognitionResult.Text);
             }
         }
         catch (Exception ex)
         {
             MessageBox.Show(ex.Message);
         }
 }

当我运行应用程序并单击按钮说话时，它会显示消息确认几秒钟然后消失。

注意：我直接在我的手机上测试这个应用程序。（诺基亚 Lumia 920）

That error message means that the language isn't supported. I'm not sure what your language settings are but you can get the recognizer with your locale using this (swap en-GB with the culture you want)

var localRec = InstalledSpeechRecognizers.All
                       .Where(r => r.Language == "en-GB").FirstOrDefault();

Then set your recognizer with that language

if(localRec != null)
  recognizer.Recognizer.SetRecognizer(localRec);
else
  MessageBox.Show("Recognizer with the language not found");

If you don't explicitly set the locale above then the system will use the language set in the phone's Speech settings.
