SetInputToWaveFile

Question

我是c#的新手，目前正在从事一个项目，该项目涉及到我使用音频文件作为输入，并将其作为文本写入。我有使用system.speech的代码。我从http://blog.thomascsherman.com/2009/08/getting-started-with-windows-voice-recognition/获得了这段代码并进行了编译，但我在运行时遇到了问题。一旦我运行它，代码就会崩溃，控制台会说“找不到输入文件”。我意识到输入文件的路径是什么，并且我知道文件在那个文件夹中。请帮我处理这个。我正在粘贴下面的代码。

使用系统；使用System.IO；使用System.Speech；使用System.Speech.Recognition；使用System.Speech.AudioFormat；

public static void Main()

     Hello hello= new Hello();
        hello.doStuff();


}



private void doStuff()
{
    SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
    sre.SpeechHypothesized += new EventHandler<SpeechHypothesizedEventArgs>(sre_SpeechHypothesized);
    sre.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(sre_SpeechRecognized);
    sre.RecognizeCompleted += new EventHandler<RecognizeCompletedEventArgs>(sre_RecognizeCompleted);
    sre.AudioSignalProblemOccurred += new EventHandler<AudioSignalProblemOccurredEventArgs>(sre_AudioSignalProblemOccurred);
    sre.SpeechDetected += new EventHandler<SpeechDetectedEventArgs>(sre_SpeechDetected);
    sre.SpeechRecognitionRejected += new EventHandler<SpeechRecognitionRejectedEventArgs>(sre_SpeechRecognitionRejected);



    DictationGrammar dg = new DictationGrammar();
    sre.LoadGrammar(dg);


    sre.SetInputToWaveFile("hello.wav");
    sre.EndSilenceTimeout = new TimeSpan(0, 0, 2);


    sre.RecognizeAsync();
}

 void sre_SpeechHypothesized(object sender, SpeechHypothesizedEventArgs e)
{
    Console.WriteLine(e.Result.Text);
}
 void sre_AudioSignalProblemOccurred(object sender, AudioSignalProblemOccurredEventArgs e)
{
    Console.WriteLine(e.AudioSignalProblem.ToString());
}

 void sre_SpeechRecognitionRejected(object sender, SpeechRecognitionRejectedEventArgs e)
{
Console.WriteLine("Rejected!");
}

 void sre_RecognizeCompleted(object sender, RecognizeCompletedEventArgs e)
{
Console.WriteLine("Recognition Complete!");
}

 void sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
Console.WriteLine(e.Result.Text);
}

 void sre_SpeechDetected(object sender, SpeechDetectedEventArgs e)
{
Console.WriteLine("Speech Detected!");
}


}

首先，尝试设置一个绝对路径(即@"C:/my/file/is/here/hello.wav")，以确定路径是问题所在还是其他原因。

还请注意，版本和Debug构建有不同的文件夹，有时会让人感到困惑。确保该文件确实位于正确的文件夹中(为了测试这是否是问题所在，首先将hello.wav放在really和Debug文件夹中)。
