语音识别在此系统上不可用.无法找到SAPI和语音识别引擎

Question

美好的一天!我尝试使用Speech SDK 11编写简单的语音到文本引擎.所以尝试从这个例子执行测试.

所以,我只是创建控制台应用程序并运行代码.(有任务)

 Task speechRecognizer = new Task(DoWork);
        speechRecognizer.Start();
        speechRecognizer.Wait();

static void DoWork()
    {

        // Create a new SpeechRecognitionEngine instance.
        SpeechRecognitionEngine sre = new SpeechRecognitionEngine();

        // Configure the input to the recognizer.
        sre.SetInputToWaveFile(@"c:\Test\Colors.wav");

        // Create a simple grammar that recognizes "red", "green", or "blue".
        Choices colors = new Choices();
        colors.Add(new string[] { "red", "green", "blue" });

        // Create a GrammarBuilder object and append the Choices object.
        GrammarBuilder gb = new GrammarBuilder();
        gb.Append(colors);

        // 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();
    }

但我得到了这个例外:此系统无法使用语音识别功能.无法找到SAPI和语音识别引擎.我尝试安装SpeechSDK51,但没有结果.

你能告诉我如何解决这个错误吗？

谢谢!

PS错误出现在:

 // Create a new SpeechRecognitionEngine instance.
    SpeechRecognitionEngine sre = new SpeechRecognitionEngine();

您是否添加了运行时组件的x64和x86版本？它对我有用.
