這篇文章主要為大家詳細(xì)介紹了C# windows語音識(shí)別與朗讀實(shí)例，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

C# windows語音識(shí)別與朗讀示例，供大家參考，具體內(nèi)容如下

本示例通過windows語音識(shí)別功能進(jìn)行語音識(shí)別和文本朗讀。

打開windows麥克風(fēng)，點(diǎn)擊start按鍵，大聲朗讀 “中國(guó)”、“美國(guó)”、“英國(guó)”，識(shí)別成功將發(fā)出“嘟”的提示音并朗讀對(duì)應(yīng)結(jié)果。

用到的語音識(shí)別模塊包括：

using System.Speech.Recognition;
using System.Speech.Synthesis;

動(dòng)態(tài)連接庫文件在我的資源中下載.System.Speach.dll

示例界面如下：

程序源碼如下：

using System;
using System.Runtime.InteropServices;
using System.Speech.Recognition;
using System.Speech.Synthesis;
using System.Threading;
using System.Windows.Forms;

namespace Test
{
    public partial class FormVoiceControl : Form
    {
        static SpeechSynthesizer SS = new SpeechSynthesizer();
        private SpeechRecognitionEngine SRE = new SpeechRecognitionEngine(); //語音識(shí)別模塊
        private bool SRE_listening = false;
        private int wordid;
        private string shibie;

        [DllImport("kernel32.dll")]
        public static extern bool Beep(int freq, int duration);

        public FormVoiceControl()
        {
            InitializeComponent();
        }

        public void InitVoice()  //語音識(shí)別初始化
        {
            //SS.SelectVoice("lily");
            SRE.SetInputToDefaultAudioDevice();  // 默認(rèn)的語音輸入設(shè)備，也可以設(shè)定為去識(shí)別一個(gè)WAV文

            GrammarBuilder GB = new GrammarBuilder();

            GB.Append(new Choices(new string[] { "中國(guó)", "美國(guó)", "英國(guó)"}));

            DictationGrammar DG = new DictationGrammar();

            Grammar G = new Grammar(GB);

            G.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(G_SpeechRecognized);  //注冊(cè)語音識(shí)別事件

            SRE.EndSilenceTimeout = TimeSpan.FromSeconds(2);

            SRE.LoadGrammar(G);

        }

        void G_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {
            Beep(500, 500);//已識(shí)別提示音

            string result = e.Result.Text;            
            switch (result)
            {
