对COM组件的调用返回了SpeechRecognitionEngine错误HRESULT E_FAIL

Question

我正在运行一些简单的main方法代码，该代码实例化一个SpeechRecognitionEngine并将一些语法数据传递给它。我似乎找不到为什么错误总是出现。我尝试删除.csproj和.suo，但没有任何变化。

        SpeechRecognitionEngine spe = new SpeechRecognitionEngine();
        Choices commands = new Choices();
        commands.Add("hello", "what is your name");
        GrammarBuilder gB = new GrammarBuilder(commands);
        Grammar g = new Grammar(gB);

        //every single call to spe.SomeMethod() breaks with the error in the title
        spe.LoadGrammarAsync(g);
        spe.SetInputToDefaultAudioDevice();

        spe.RecognizeAsync(RecognizeMode.Multiple);

Answer 1

好了，弄明白了:转到: Build>Configuration Manager>Active Solution Platform单击“Any CPU”下拉列表。选择Set the platform to the compatible Speech SDK type (在我的例子中是x64)，享受正在开发的机器人服务程序

ps。省去麻烦，使用RecognizeAsync()和not Recognize()。由于某些原因，Recognize喜欢执行两次。
