is there a way to record the volume of a vocal response within Eprime itself?

[David McFarlane]

Well, to start with, sound "volume" is a very fuzzy notion:  Does it 
mean total integral power across the audio spectrum for the full 
duration of a vocal response?  Does it mean spectral power sliced 
into time samples, say for every 100 ms period?  And would this be 
weighted for human auditory sensitivity?  Etc.

Beyond that, you face several technical hurdles, unless you can find 
a machine that just does the job for you.  Offhand I would say that 
you would have to have EP2 record the full sound from the 
subject.  Then, after the experiment, you would run each response 
sound file through an audio spectrum analysis program to calculate 
whatever measure you like.  But you would still have to take account 
of amplifications and attenuations introduced by your recording 
equipment.  No small order!  OTOH, if you wanted merely *relative* 
audio intensity rather than *absolute* intensity then that would 
simplify matters a bit.

So the simple answer is no, I cannot see anyway to do what you wish 
with E-Prime.
