主题：关于语音库的问题

Dim sp As new DotNetSpeech.SpVoice()

For Each st As Dotnetspeech.SpObjectToken In sp.GetVoices
    Output.Show(st.GetDescription)
Next

运行以上代码，会显示:

Microsoft Sam

IQ Cherry

IQ John

IQ Annie

Microsoft Simplified Chinese

ScanSoft Sin-Ji_Full_22kHz

然后：

DIM n as integer = 0

sp.Voice = sp.GetVoices(String.Empty,String.Empty).Item(n) 

sp.rate = 0

sp.Speak("text", DotNetSpeech.SpeechVoiceSpeakFlags.SVSFlagsAsync)

当n=0,4,5都能正确播报语音，但n=1,2,3时就报错

我知道第1,2,3个语音库是安装得不正确，但现在怎样处理呢？
