Answer 2

安装SpeechSDK51和 SpeechSDK51LangPack
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=5e86ec97-40a7-453f-b0ee-6583171b4530&displaylang=en
在vo.Speak(content, SSF);前，设置属性
vo.Voice = voice.GetVoices(string.Empty, string.Empty).Item(3)；SpeechSDK51LangPack支持中文发音，对应Item中参数3应该是个女音
我用speechlib是这样的，dotnetspeech中的不知道是不是一样
