花了一上午来弄这个。。结果到群里问了下。。给了个更简单的。。直接调用系统内置的。。
private void Button_Click(object sender, RoutedEventArgs e)
{
// Initialize a new instance of the SpeechSynthesizer.
using (SpeechSynthesizer synth = new SpeechSynthesizer())
{
// Configure the audio output.
synth.SetOutputToDefaultAudioDevice();
// Speak a string synchronously.
synth.Speak("请第38号患者李娟娟到华兴诊室就诊");
}
}
