If I'm understanding things correctly, could something like this work?
http://www.national.com/pf/LM/LM3354.html
It appears to be able to take 2.5 - 5.5v in and give up to 5v out at
up to 90mA. It would be great if it could be powered from the sensor
port directly instead of having to string another battery pack off the
side...

This is basically what that SpeakJet chip does. It would be hard to
fit enough phonemes into memory and I believe you'd need some way to
change the playback speed of the individual parts.

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?
