JARVIS 语音识别程序不听语音输入

Question

我最近决定研究 C#，因为我在 YouTube 上找到了一个关于用它创建 JARVIS 语音识别程序的很棒的教程。我完全按照教程进行了操作，并且成功地完成了运行，没有任何错误。但是，它没有响应我的语音输入，从代码中可以看出，输入是 "hello" 我已经尝试过，但无法让它响应。根据视频的评论，我不是唯一发生这种情况的人，您能帮我找出造成这种情况的原因吗？谢谢你。这是完整的代码：

我也一直在使用 C# 进行语音识别。 C# 语音识别并不像你想象的那样工作。它匹配获得的输入的最佳组合，然后根据它进行，所以你必须根据它进行编码。最好的方法是使用 e.Result.Text 找到当你说一个词时它实际识别的内容，然后像这样编码。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Speech.Recognition;
using System.Speech.Synthesis;
using System.IO;
using System.Xml;

namespace J.A.R.V.I.S
{
    public partial class Form1 : Form
    {
        SpeechRecognitionEngine _recognizer = new SpeechRecognitionEngine();
        SpeechSynthesizer JARVIS = new SpeechSynthesizer();
        string QEvent;
        string ProcWindow;
        double timer = 10;
        int count = 1;

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        _recognizer.SetInputToDefaultAudioDevice();
        _recognizer.LoadGrammar(new DictationGrammar());
        _recognizer.LoadGrammar(new Grammar(new GrammarBuilder(new Choices(File.ReadAllLines(@"C:\Users\chaye\Documents\Commands.txt")))));
        _recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(_recognizer_SpeechRecognized);
        _recognizer.RecognizeAsync(RecognizeMode.Multiple);
    }

    void _recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {

        string speech = e.Result.Text;
        MessageBox.Show(speech);
        string[] start_array={"start","some other words that sounds same as start or result from e.Result.Text when you say start"};
        if(start_array.Contains(speech))
          {
            SendKeys.SendWait("^{ESC}");
          }

    }
  }
}
