美好的一天！这是关于Microsoft Server Speech SDK v11.0（服务器版）的。

我在 MSDN sample 运行了测试示例。所以英语短语 -red,blue - 被很好地识别。但我也想识别俄语 - 安装 Microsoft Speech Recognition Language -TELE (ru-RU) 并运行我的应用程序/

代码：

 static void DoWork()
    {

        Thread.CurrentThread.CurrentCulture = new CultureInfo("ru-RU");
        Thread.CurrentThread.CurrentUICulture = new CultureInfo("ru-RU");

        // Create a new SpeechRecognitionEngine instance.
        SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
        
        // Configure the input to the recognizer.
        sre.SetInputToWaveFile(@"c:\Test\красный.wav");
        
        // Create a simple grammar that recognizes "red", "green", or "blue".
        Choices colors = new Choices(); 
       // colors.Add(new string[] { "red", "green", "blue","красный" });
        colors.Add(new string[] { "красный" }); //russian word- "red"
        
        // Create a GrammarBuilder object and append the Choices object.
        GrammarBuilder gb = new GrammarBuilder();
        gb.Culture = new CultureInfo("ru-RU"); // add Culture Info

        gb.Append(colors);

        Console.WriteLine(gb.Culture.CultureTypes);

        // Create the Grammar instance and load it into the speech recognition engine.
        Grammar g = new Grammar(gb);
        sre.LoadGrammar(g);

        // Register a handler for the SpeechRecognized event.
        sre.SpeechRecognized +=
          new EventHandler<SpeechRecognizedEventArgs>(sre_SpeechRecognized);

        // Start recognition.
        sre.Recognize();
    }
   
    // Create a simple handler for the SpeechRecognized event.
    static void sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
        Console.WriteLine(String.Format("Speech recognized: {0}",e.Result.Text));
      
    }

错误出现在这一行：

 sre.LoadGrammar(g);

The language for the grammar does not match the language of the speech recognizer.

那么，如何解决这个错误呢？我尝试设置 CultureInfo，但它不起作用... 谢谢！

【解决方案1】：

更改GrammarBuilder.Culture 属性将解决此错误。

之后：

GrammarBuilder gb = new GrammarBuilder();

添加：

gb.Culture = Thread.CurrentThread.CurrentCulture

使语法文化与识别器匹配。

【讨论】：

这个答案是错误的。线程的文化完全无关紧要，它可以是任何东西。您必须设置 GrammarBuilder.Culture = myCulture 和 new SpeechRecognitionEngine(myCulture);然后异常就消失了。

【解决方案2】：

看来你需要

SpeechRecognitionEngine recognizer =
        new SpeechRecognitionEngine(
          new System.Globalization.CultureInfo("ru-RU")))

【解决方案3】：

语法构建器文化必须与语音识别器相匹配。最简单的方法是将语法文化设置为与语音识别器相同，如下所示：

var sr = new SpeechRecognizer();
var gb = new GrammarBuilder();

// set the culture
gb.Culture = sr.RecognizerInfo.Culture;
