错误是对象引用未设置为对象的实例."

            voice.Speak("Hello World!", SpeechVoiceSpeakFlags.SVSFDefault);//<---- here is the error

推荐答案

Form_Load或Form_Shown中的错误可能被误吞了(我不记得在其上找到更多信息的网站). /> 因此，我认为voice = new SpVoice();失败了.您可以在其周围添加一个try-catch(在这种情况下，由于catch子句在同一函数中，因此它将被catch子句捕获)，从而获得有关失败原因的更多信息.
可能有32位与64位问题.

Errors in Form_Load or also Form_Shown may happen to be swallowed (I do not remember the web site where I found more information on it).
Hence I think that voice = new SpVoice(); failed. You can add a try-catch around it (in this case, the error will be caught by the catch clause because it is in the same function) and thus get more information about the reason of the failure.
There could be e.g. a 32bit vs. 64bit issue.
