Question

我已经在 C# 中创建了将文本转换为语音的程序，但无论我选择什么性别，它都会说相同的声音！性别总是相同的？我去了语音属性，它说我只有 Microsoft Anna 的声音。

从SpeechSynthesizer.SelectVoiceByHints方法的 MSDN 页面：

使用 GetInstalledVoices 方法和 VoiceInfo 类获取您可以选择的已安装文本到语音 (TTS) 语音的名称。 SpeechSynthesizer 对象选择第一个安装的声音，其 Gender 属性与性别参数匹配。

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，因此它可能默认为任何性别的第一个声音……这将是 Microsoft Anne，因为这是您唯一的声音已经安装。

安装声音的过程与 SO 无关，因为它与编程无关。 不过，这是 SuperUser 上的一个解决方案，涵盖了它。
