That would be the LOWSPEED_9V flag?

I just might do that.

The chip used in the book I have is the SpeakJet
http://www.acroname.com/robotics/parts/R225-SPEAKJET.html It's a LOT
cheaper than the sp03, however, it uses a serial interface and would
be a lot more complicated. I'd have to figure out a way to convert
the i2c signals into serial commands and it works by sending
allophones instead of arbitrary text. I did find a page that
describes a way to add i2c to it, but it's a little beyond my
understanding at the moment
http://www.modularsynthesis.com/modules/synthmodules/PSIM-SpeakJet/PSIM-speakjet.htm
That or preload phrases and use the digital inputs to trigger them,
neither of which would be as nice as just sending an i2c message to
say "Shall we play a game". Although I must admit, the speakjet can
output some pretty cool bleeps and blops sound effects like r2d2 and
overall has a cooler sounding retro robot voice. :)

It sounds like the NXT probably doesn't have enough power available to run that chip, but you might look at using a BUC (Boost-Up Converter) component to bring the 4.3V supply up to a higher level?
