Question

我使用语音识别创建了一个C＃项目，其中我有一个具有下一个和最后一个按钮的表单我想要做的是当我说下一个按钮将把我带到下一个文件或者如果我说回来它将转到上一个文件。但是在调试项目时它只显示我说的而不是它。有谁知道我该如何修复它？

这是我制作的代码：

    private void Form1_Load(object sender, EventArgs e)
    {
        SpeechRecognizer recognizer = new SpeechRecognizer();
        Choices command = new Choices();
        command.Add(new string[] { "next", "last", "first" });

        GrammarBuilder gb = new GrammarBuilder();
        gb.Append(command);

        Grammar g = new Grammar(gb);
        recognizer.LoadGrammar(g);

        recognizer.SpeechRecognized +=
              new EventHandler<SpeechRecognizedEventArgs>(sre_SpeechRecognized); 
    }


    void sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
        MessageBox.Show("Speech recognized: " + e.Result.Text);
    }
}

几年前，我有一个关于这个主题的案例研究。如果您将我的代码与您的代码进行比较，您可以找到一些东西。下面的代码改变了灯泡的状态。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Speech.Recognition;
using System.Threading;


namespace SesTanima
{
    public partial class Form1 : Form
    {
        private SpeechRecognitionEngine recognizer = new SpeechRecognitionEngine();

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            LoadGrammars();
            StartRecognition();
        }


        private void LoadGrammars() 
        {
            Choices choices = new Choices( new string[] {"Lights on", "Exit", "Zoom out", "Zoom in", "Reset", "Lights off" } );
            GrammarBuilder grammarBuilder = new GrammarBuilder(choices);
            Grammar grammar = new Grammar(grammarBuilder);
            recognizer.LoadGrammar(grammar);
        }

        private void StartRecognition() 
        {
            recognizer.SpeechDetected += new EventHandler<SpeechDetectedEventArgs>(recognizer_SpeechDetected);
            recognizer.SpeechRecognitionRejected += new EventHandler<SpeechRecognitionRejectedEventArgs>(recognizer_SpeechRecognitionRejected);
            recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);
            recognizer.RecognizeCompleted += new EventHandler<RecognizeCompletedEventArgs>(recognizer_RecognizeCompleted);


            Thread t1 = new Thread(delegate()
            {            
                recognizer.SetInputToDefaultAudioDevice();
                recognizer.RecognizeAsync(RecognizeMode.Single);
            });
            t1.Start();
        }

        private void recognizer_SpeechDetected(object sender, SpeechDetectedEventArgs e) 
        {
            textBox1.Text = "Recognizing voice command...";     
        }

        private void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e) 
        {
            if (e.Result.Text == "Lights on")
            {
                pictureBox1.Image = Properties.Resources.lightsOn;
            }
            else if (e.Result.Text == "Lights off")
            {
                pictureBox1.Image = Properties.Resources.lightsOff;
            }
            else if ( e.Result.Text == "Exit" )
            {
                recognizer.Dispose();
                Application.Exit();

            }
            else if ( e.Result.Text == "Zoom out" )
            {
                pictureBox1.Size = new System.Drawing.Size( 135, 107 );
            }
            else if ( e.Result.Text == "Zoom in" )
            {
                pictureBox1.Size = new System.Drawing.Size( 538, 426 );
            }
            else if ( e.Result.Text == "Reset" )
            {
                pictureBox1.Size = new System.Drawing.Size( 269, 213 );
            }
            textBox1.Text = e.Result.Text;
        }

        private void recognizer_SpeechRecognitionRejected(object sender, SpeechRecognitionRejectedEventArgs e) 
        {
            textBox1.Text = "Failure.";
        }

        private void recognizer_RecognizeCompleted(object sender, RecognizeCompletedEventArgs e) 
        {
            recognizer.RecognizeAsync();
        }
    }
}
