system.speech.synthesis中的访问冲突异常

本文关键字：访问冲突 异常 speech synthesis system | 更新日期: 2023-09-27 18:09:41

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);
}

我得到这个错误:

System.AccessViolationException was unhandled

InnerException:

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

谁有解决这种问题的办法?解决方案吗?提示?有什么可以帮助解决这个恼人的问题吗?

system.speech.synthesis中的访问冲突异常

只是猜测，你正在调用_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。我可以想象这可能会导致问题。您应该在获得处理结果后处理_speech对象。
