System.FormatException：波形文件无效

Question

请看下面的代码sn-p

using System.IO;



MemoryStream stream = new MemoryStream();


SpeechSynthesizer s = new SpeechSynthesizer();
s.setOutputToWaveStream(stream);
s.Speak("hello world");


SpeechRecognitionEngine e = new SpeechRecognitionEngine(new System.Globalization.CuntureInfo("en-US");


//Set grammar code goes here

e.SetInputToWaveStream(stream);

当它到达e.SetInputToWaveStream(stream); 时，它会抛出错误System.FormatException: Wave file not valid

这里有什么问题？

发现问题。在输入之前需要调用stream.Position = 0
