SpeechSynthesizer.Speak 方法

定义

重载

注解

方法 Speak 以同步方式生成语音。 在完全朗读实例的内容之前， Speak 方法不会返回。 这是生成语音的最简单方法。 但是，如果应用程序需要在说话时执行任务，例如突出显示文本、绘制动画、监视控件或其他任务，请使用 SpeakAsync 方法或 SpeakSsmlAsync 方法异步生成语音。

在调用此方法期间， SpeechSynthesizer 可能会引发以下事件：

• StateChanged. 合成器说话状态更改时引发。

• SpeakStarted. 合成器开始生成语音时引发。

• PhonemeReached. 合成器每次到达构成语言中谨慎语音的字母或字母组合时引发。

• SpeakProgress. 合成器每次说完单词时引发。

• VisemeReached. 每次发出语音输出时，都需要改变用于生成语音的嘴或面部肌肉的位置。

• BookmarkReached. 当合成器在提示符中遇到书签时引发。

• VoiceChange. 合成器语音更改时引发。

处理SpeechSynthesizer任何Speak方法时， 不会引发 SpeakCompleted 事件。
