C# 中的空白表单使用 speech.recognition

Blank Form in C# using speech.recognition

嗨,我遇到了这种情况,我不知道如何解决。这段代码很好,错误为 0,但每当我执行 F5 时,它都会显示一个空白表格,没有声音,也无法识别,请帮忙。请我真的需要帮助有人可以帮助我吗?
现在这条线只适用于 "it look like your post is mostly code; please add some more details";

从您发布的异常来看,我认为您没有正确初始化 Grammar 和 SpeechRecognitionEngine。看来您需要为其指定一种语言/文化。从文档中: https://msdn.microsoft.com/en-us/library/hh378426(v=office.14).aspx

// Create a new SpeechRecognitionEngine instance.
SpeechRecognitionEngine sre = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en-US"));
