ASP.NET文本到语音代码在本地开发机器上工作，但不在生产服务器上

我有一个ASP.NET应用程序，它可以处理文本到语音TTS。该代码在本地机器上正常工作，但是当我将其部署在Windows 2008 R2服务器Enterprise 64位上时，应用程序池只会崩溃。该应用程序由v4.0 .NET框架构成。我在服务器上使用IIS 7。以下是应用程序池崩溃时的错误。ASP.NET文本到语音代码在本地开发机器上工作，但不在生产服务器上

Service Unavailable 

HTTP Error 503. The service is unavailable.

这是我应该添加哪些代码ealier

 MemoryStream ms = new MemoryStream(); 

     context.Response.ContentType = "audio/wav"; 

     Thread t = new Thread(() => 
     { 
      SpeechSynthesizer ss = new SpeechSynthesizer(); 
      ss.SetOutputToWaveStream(ms); 
      ss.Speak(context.Request.QueryString["tts"]); 
     }); 
     t.Start(); 

     t.Join(); 
     ms.Position = 0; 
     ms.WriteTo(context.Response.OutputStream); 
     context.Response.End();

任何帮助将不胜感激

感谢

这里是异常

的更多细节。我已将IIS_USRS的完整权限授予C：\ Program Files（x86）\ Microsoft Speech SDK 5.1 \ Bin \ TTSEng.dll文件。现在错误更改为

我的服务器上没有任何声音设备。这个例外是否正确？
