在System.Runtime.CompilerServices.AsyncMethodBuilderCore<堆栈跟踪; ThrowAsync> b__0(对象状态)}
我发现,在

解决方案
请确保您已经添加的能力 ID_CAP_SPEECH_RECOGNITION
应用程序清单(WMAppManifest.xml)。
I'm using Microsofts SpeechSynthesizer to create audio output for my Windows Phone app. I use this code
private async void TextToSpeech_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
SpeechSynthesizer synth = new SpeechSynthesizer();
await synth.SpeakTextAsync("You have a meeting with Peter in 15 minutes.");
}
I get this exception:
{System.UnauthorizedAccessException: Access is denied.
at Windows.Phone.Speech.Synthesis.SpeechSynthesizer..ctor()
at NerdQuiz.Question.<TextToSpeech_Tap>d__1.MoveNext()
--- End of stack trace from previous location where exception was thrown ---
at System.Runtime.CompilerServices.AsyncMethodBuilderCore.<ThrowAsync>b__0(Object state)}
I found out that the error occurs at
new SpeechSynthesizer();
解决方案
Make sure you have added the capability ID_CAP_SPEECH_RECOGNITION
to the application manifest (WMAppManifest.xml).
