编译器错误-c#中的语音识别
本文关键字：语音识别 -c# 错误 编译器 | 更新日期: 2023-09-27 17:58:23
我试图用C#做一个简单的语音识别表单，但遇到了问题。这方面很新，所以请帮忙！
面临2个错误：第一个错误是："[预期]"第二个错误是：无效的令牌"；"在类、结构或接口成员声明中
以下是我的代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Speech.Recognition;
using System.Text.RegularExpressions;
using System.Diagnostics;
namespace Speech
{
public class Grammar;
public partial class Form1 : Form
{
private SpeechRecognitionEngine recognitionEngine;
public Form1()
{
InitializeComponent();
recognitionEngine = new SpeechRecognitionEngine();
recognitionEngine.SetInputToDefaultAudioDevice();
recognitionEngine.SpeechRecognized += (s, args) =>
{
string line = "";
foreach (RecognizedWordUnit word in args.Result.Words)
{
if (word.Confidence > 0.8f)
line += word.Text + " ";
}
string command = Regex.Replace(line, "Start", "").Trim();
switch (command)
{
case "Notepad":
Process.Start("notepad.exe");
break;
case "Calculator":
Process.Start("calc.exe");
break;
case "Paint":
Process.Start("mspaint.exe");
break;
}
txtOutput.Text += line;
txtOutput.Text += Environment.NewLine;
};
recognitionEngine.LoadGrammar(CreateGrammarObject());
}
private void button_start_Click(object sender, EventArgs e)
{
recognitionEngine.RecognizeAsync(RecognizeMode.Multiple);
}
private void button_stop_Click(object sender, EventArgs e)
{
recognitionEngine.RecognizeAsyncStop();
}
}
private Grammar CreateGrammarObject()
{
Choices commandChoices = new Choices("Calculator", "Notepad", "Internet Explorer", "Paint");
GrammarBuilder grammarBuilder = new GrammarBuilder("Start");
grammarBuilder.Append(commandChoices);
Grammar g = new Grammar(grammarBuilder);
return g;
}
}
}
这是什么？：
public class Grammar;
public partial class Form1 : Form
从类的结构来看，您似乎正在构建一个Form。那么Grammar是从哪里来的呢？完全删除第一个类声明至少可以修复语法错误：
public partial class Form1 : Form
必须在VisualStudio中添加：dataAI文本框、startBtn按钮、BtnClear按钮、stopBtn按钮和textBox1文本框+Speech。如果你有任何问题，请联系我！
