JARVIS语音识别程序不听语音输入

Question

我最近决定查看C＃，因为我在YouTube上找到了一个关于在其中创建JARVIS语音识别程序的很酷的教程。我完全遵循了教程，并设法让它运行完全没有任何错误。但是，它没有响应我的语音输入，因为在代码中可以看到输入是＆＃34;你好＆＃34;我已经尝试过这个并且无法做出回应。根据对视频的评论，我不是唯一发生的事情，请你帮我找一下造成这种情况的原因？谢谢。这是完整的代码：

我也一直致力于c＃中的语音识别。 C＃语音识别并不像你想象的那样有效。它匹配获得的输入的最佳组合，然后根据它进行，因此您必须根据它进行编码。最好的方法是使用e.Result.Text来查找当你说出一个单词时它实际识别出来的内容，然后像这样编码。
