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.wavsp.Speak("13213213213213");}
