# 语音播报 #

添加引用：System.Speech.Synthesis或Microsoft.Speech.Synthesis

public static void Speaking(string saying)
            {
                string say = saying;
                Task task = new Task(() =>
                {
                    SpeechSynthesizer speech = new SpeechSynthesizer();
                    speech.Volume = 100; //音量
                    speech.SetOutputToDefaultAudioDevice();//设定默认音频设备
                    CultureInfo keyboardCulture = System.Windows.Forms.InputLanguage.CurrentInputLanguage.Culture;//获取当前输入语言的区域性
                    InstalledVoice neededVoice = speech.GetInstalledVoices(keyboardCulture).FirstOrDefault();
                    if (neededVoice == null)
                    {
                        say = "未知的操作";
                    }
                    else
                    {
                        speech.SelectVoice(neededVoice.VoiceInfo.Name);
                    }
    
                    string str = say + "," + say + "," + say;
    
                    speech.SpeakAsync(str);//异步播报
                });
                task.Start();
    
            }

# 语音识别 #

添加引用：System.Speech.Recognition

SpeechRecognitionEngine recognizer = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("zh-CN"));//初始化中文引擎
                Choices conmmonds = new Choices();
                conmmonds.Add(new string[] { "导通", "断开" });//添加词条
                GrammarBuilder gBuilder = new GrammarBuilder();
                gBuilder.Append(conmmonds);
                Grammar grammar = new Grammar(gBuilder);
                recognizer.LoadGrammar(grammar);
                recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(Deal_SpeechRecongized);
                recognizer.SetInputToDefaultAudioDevice();//设置默认输入设备
                recognizer.RecognizeAsync(RecognizeMode.Multiple);//开始监控设备输入准备识别
    
                static void Deal_SpeechRecongized(object sender, SpeechRecognizedEventArgs e) //处理识别结果
                {
                    Console.WriteLine("识别结果：" + e.Result.Text);
                }

Windows7或XP系统语音播报会报BUG如图所下：

**检索COM类工厂中CLSID为\{D9F6EE60-58C9-458B-88E1-2F908FD7F87C\}的组件失败，原因是出现以下错误：8007007e找不到指定的模块**错误

解决方案：

1.  在项目引用中选中System.Speech，右键打开属性，将嵌入互操作类型及特定版本选为False，如下图所示
    
    1.  ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_Q1NETiBA5qix6Iqx6Iqx_size_17_color_FFFFFF_t_70_g_se_x_16][]
2.  检查系统存不存在语音识别模块，一部分Windows7系统可能由于安装系统时去除了一部分包括语音识别功能组件，导致sapi.dll文件不存在，所以就会爆出上述错误，没有讲述人语言包。
    
    1.  打开控制面板，切换为小图标，正常会看到语音识别图标，而功能缺乏的系统会找不到语音识别
    2.  ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_Q1NETiBA5qix6Iqx6Iqx_size_54_color_FFFFFF_t_70_g_se_x_16][]
    3.  如果没有则需要下载Windows7系统TTS修复，下载链接在文章底部，csdn 1积分下载，无积分上传审核不通过
    4.  需要注意的是即使下载修复软件进行修复后，控制面板中出现了语音识别图标，但运行语音识别软件后，但可能会爆出“无法创建所需的引擎ID”类似错误，这时需要将麦克风插入计算机中，然后重启软件，如果依然存在问题，说明修复未成功，Debug失败
