var speechEngine = new SpVoiceClass();
SetVoice(speechEngine, job.Voice);

var fileMode = SpeechStreamFileMode.SSFMCreateForWrite;
var fileStream = new SpFileStream();
try
{
    fileStream.Open(filePath, fileMode, false);
    speechEngine.AudioOutputStream = fileStream;
    speechEngine.Speak(job.Script, SpeechVoiceSpeakFlags.SVSFPurgeBeforeSpeak | SpeechVoiceSpeakFlags.SVSFDefault); //TODO: Change to XML
    //Wait for 15 minutes only
    speechEngine.WaitUntilDone((uint)new TimeSpan(0, 15, 0).TotalMilliseconds);
}
finally
{
    fileStream.Close();
}

这个确切的代码在 WinForm 应用程序中工作，但是当我在 web 服务中运行它时，我得到以下

System.Runtime.InteropServices.COMException was unhandled
  Message="Exception from HRESULT: 0x80045003"
  Source="Interop.SpeechLib"
  ErrorCode=-2147201021

有谁知道可能导致此错误的原因？错误代码的意思

SPERR_UNSUPPORTED_FORMAT

为了完整起见，这里是 SetVoice 方法

void SetVoice(SpVoiceClass speechEngine, string voiceName)
{
    var voices = speechEngine.GetVoices(null, null);
    for (int index = 0; index < voices.Count; index++)
    {
        var currentToken = (SpObjectToken)voices.Item(index);
        if (currentToken.GetDescription(0) == voiceName)
        {
            speechEngine.SetVoice((ISpObjectToken)currentToken);
            return;
        }
    }
    throw new Exception("Voice not found: " + voiceName);
}

我已授予对要写入文件的文件夹 C:\Temp 上的用户的完全访问权限。任何帮助，将不胜感激！

我不认为 System.Speech 在 Windows 服务中工作。看起来对 Shell 存在依赖关系，而服务对它不可用。尝试与 SAPI 的 C++ 接口互操作。System.Runtime.InteropServices 中的某些类可能对此有所帮助。

Our naming convention requires us to use a non-standard file extension. This works fine in a Winforms app, but failed on our web server. Changing the file extension back to .wav solved this error for us.

Make sure you explicitly set the format on the SPFileStream object. ISpAudio::SetState (which gets called in a lower layer from speechEngine.Speak) will return SPERR_UNSUPPORTED_FORMAT if the format isn't supported.

I just got the webservice to spawn a console app to do the processing. PITA :-)
