C#: Speech Synth with PromptBuilder not working right

I'm of course guessing something is wrong with my computer, maybe a library somewhere.. not sure. First off, at home, I can't get a male voice. I figure this is because it has a different library at home, on Win7 Ultimate. If anyone has any thoughts, I'd appreciate it. On my work PC, winXP SP3 (.NET 4), I can get a male voice.... but... pbuilder doesn't work right:

pbuilder.StartStyle(pStyle);
pbuilder.StartParagraph();
pbuilder.StartVoice(VoiceGender.Male, VoiceAge.Teen, 2);
pbuilder.StartSentence();
pbuilder.AppendText("Checking current weather.");
pbuilder.EndSentence();
pbuilder.EndVoice();
pbuilder.EndParagraph();
pbuilder.EndStyle();
ss.SpeakAsync(pbuilder);

Works at home... but at work, all it says (and I'm not joking) is "Blah". If I put:

ss.SpeakAsync("Checking current开发者_运维技巧 weather");

Then it will say that. ???

In case anyone is interested, I'm working on building my own... mini Jarvis (from Iron Man) http://code.google.com/p/jarvisv2win7/

At the time of this writing, has speech recognition, will recognize given commands (Play Tchaikovsky.... Check email.. How cold is it?... etc)

You can't get a male voice on Windows 7 because there is no male voice installed on windows 7 by default.

XP has two English voices (Microsoft Sam and Microsoft Mary) installed by default, but Windows Vista and Windows 7 only have one English voice (Microsoft Anna) installed by default. Therefore, on Windows 7, you won't be able to select a male voice because one is not installed.

According to the documentation for the PromptBuilder class, Windows XP is not a supported platform.
