语言播报

            SpeechSynthesizer sp = new SpeechSynthesizer();                         sp.Rate = 1;//语速  -10 到 10 之间             sp.Volume = 50;//音量 （0 到 100）             PromptBuilder pb = new PromptBuilder();             pb.AppendText("123");             sp.Speak(pb); 

获取语言包、异步播报、暂停、停止、继续语言播报、保存音频

》》异步播报，就是不阻塞其它操作

            SpeechSynthesizer sp = new SpeechSynthesizer();                         sp.Rate = 1;//语速  -10 到 10 之间             sp.Volume = 50;//音量 （0 到 100）             PromptBuilder pb = new PromptBuilder();             pb.AppendText("1234564878564135415648145");             //同步播报             //sp.Speak(pb);             //异步播报             sp.SpeakAsync(pb); 

》》获取语言包

           SpeechSynthesizer sp = new SpeechSynthesizer();             foreach (var item in sp.GetInstalledVoices())             {                 this.comboBox1.Items.Add(item.VoiceInfo.Name);             } 

》》 异步播报 暂停、继续

if (sp.State == SynthesizerState.Speaking)             {                 // 正在播报 暂停                 sp.Pause();             }             else if (sp.State == SynthesizerState.Paused)             {                 // 已经 暂停，继续播放                 sp.Resume();             } 

》》停止

       if (sp.State == SynthesizerState.Speaking)             {                 //取消所有排队、异步、语音合成操作。                 sp.SpeakAsyncCancelAll();             } 

》》保存音频

          //使用using才能在结束后自动保存语音文件             using (SpeechSynthesizer sp = new SpeechSynthesizer())             {                 string path = @"D:\\zenvideo\";                 sp.SetOutputToWaveFile(path + "1.wav");                 //这句不会播报的，会把声音生成到1.wav                 sp.Speak("13213213213213");             }
