当像这样使用 system.speech.synthesis 时：

using (_speech)
{
    _speech.SelectVoice("Anne");
    _speech.SpeakCompleted += OnSpeakCompleted;
    _speech.Rate = Convert.ToInt32(Rate);
    _speech.Volume = Convert.ToInt32(Volume);
    _speech.SpeakAsync(text);
}

我收到此错误：

System.AccessViolationException was unhandled

InnerException:

创建语音合成器的对象时不会发生错误，但在使用它时会发生错误。外汇。改变速率、音量等。

有没有人有解决这种问题的方法？解决方案？提示？有什么可以帮助解决这个烦人的问题吗？

只是猜测，您正在调用 _speech.SpeakAsync(text); 这意味着您正在使用语音异步，在下一行中，您通过关闭 using 来处理 _speech 对象。我可以想象这会导致问题。在获得处理结果后，您应该处置 _speech 对象。
