You could have Dr. Sbaitso say whatever you typed, by telling him to 'say' something. As pre-teens, my sister and I used to laugh maniacally with this basic TTS system. Typing in 'winkle tinkle' like a dozen times and hearing him say it in his special cadence still kind of cracks me up.

I also won the middle school science fair with a program that came with the SB Pro, called VEDIT2, if I recall. I set up a tape recording of a standard sound and moved a dish-shaped snow sled different distances from the microphone while recording the standard sound. I used VEDIT2 to measure the peak amplitude and then compared with expectations from a parabolic focusing reflector. Any middle schooler using the word 'directrix' was sure to win in my small town.

And yeah my dad helped with the math.

Good old SBPro though.

EDIT: ah this site has a thing for SB Pro too, and it has vedit2: http://www.vgmpf.com/Wiki/index.php/Sound_Blaster_Pro_(DOS)
