Question

當使用system.speech.synthesis這樣的：

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

我得到這個錯誤：

System.AccessViolationException was unhandled 
Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

當創建一個不發生錯誤語音合成器的對象，但使用它時發生。 FX。改變費率，數量等

有沒有人有這種問題的解決方案？解？提示？有什麼可以幫助解決這個惱人的問題？

只是一個猜測，你打電話給_speech.SpeakAsync（文本）;這意味着您正在使用語音異步，在下一行中通過關閉使用來處理_speech對象。我可以想象這會導致問題。處理結果後，應該拋棄_speech對象。
