Do you feel that it would be strongly advantageous to set these on the 
SynthesisDriver rather than the Voice?  Some of your suggestions seem to 
me to belong very much to the Speaker, for instance dialect, number 
mode, and probably dictionary.  Unless there is a compelling reason why 
these cannot or should not be applied to Speaker, I'd prefer to use the 
existing Speaker API for setting them.
