解决方案

如果您使用  等待 运算符，则在语音完成后才会返回。

 await synthesizer.SpeakTextAsync（" speech text"）; 
 //演讲结束

Hi Everyone,

how does one know when SpeakTextAsync is done? I have an app where it speaks some text, then need to prompt for a response. How do I know when the the SpeechSynthesizer has completed?

解决方案

If you use the await operator, it doesn't return until after the speech is completed.

    await synthesizer.SpeakTextAsync("speech text");
    // speech is completed
