在初始化时SpeechSynthesizer UnauthorizedAccessException [英] UnauthorizedAccessException when initializing SpeechSynthesizer

问题描述

我使用微软SpeechSynthesizer为我的Windows Phone应用程序创建音频输出。我使用此代码

 专用异步无效TextToSpeech_Tap（对象发件人，System.Windows.Input.GestureEventArgs E）
 { 
 SpeechSynthesizer合成=新SpeechSynthesizer（）; 
 
等待synth.SpeakTextAsync（你必须在15分钟内与Peter开会。）; 
} 
  

我得到这个异​​常：

  {System.UnauthorizedAccessException的：访问被拒绝。 
 
在Windows.Phone.Speech.Synthesis.SpeechSynthesizer..ctor（）
在NerdQuiz.Question< TextToSpeech_Tap> d__1.MoveNext（）
 ---完从以前的位置，引发异常--- 
在System.Runtime.CompilerServices.AsyncMethodBuilderCore<堆栈跟踪; ThrowAsync> b__0（对象状态）} 
  

我发现，在

 新SpeechSynthesizer（） ; 
  

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).
