来自 SpeechSynthesizer.SelectVoiceByHints 方法的 MSDN 页面：

使用 GetInstalledVoices 方法和 VoiceInfo 类来获取您可以选择的已安装文本转语音 (TTS) 语音的名称。 SpeechSynthesizer 对象选择 Gender 属性与性别参数匹配的第一个已安装语音。

因此，如果您选择女性，那么它将选择 Microsoft Anne。如果您选择男性，它将寻找男性声音，但由于您没有安装任何声音，因此可能默认为 any 性别的第一个声音......这将是 Microsoft Anne ，因为这是您安装的唯一一个。

安装声音的过程与 SO 无关，因为它与编程无关。 Here's a solution on SuperUser that covers it, though.
