Voice SDK - Languages

I am posting here as it doesn't let me post in the the SDK forums.

I am trying to understand how to use the Dictation feature of the Voice SDK in languages other than English. I think I can set the default to a language and maybe change the configuration? Not sure. Also how could I have more than one language active? I would like it to detect and understand different languages, or at worst be able to change from some menu setting at runtime.
