粤语语音包，调用时候选择voice名称为ScanSoft Sin-Ji_Full_22kHz即可调用

Type type = Type.GetTypeFromProgID("SAPI.SpVoice"); dynamic spVoice = Activator.CreateInstance(type); for (int i = 0; i < spVoice.GetVoices(string.Empty, string.Empty).Count; i++) { if (spVoice.GetVoices(string.Empty, string.Empty).Item(i).GetDescription(0) == "ScanSoft Sin-Ji_Full_22kHz") { spVoice.Voice = spVoice.GetVoices(string.Empty, string.Empty).Item(i); } } spVoice.Rate = 3; spVoice.Speak("无资料");
