语言播报
csharp
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
csharp
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
csharp
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
csharp
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
csharp
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
csharp
//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");
