Alternatives to SRBox for voice-trigger?

[Sudevan, Padmanabhan]

Chris and Ben,

 

If memory serves me right,  think the SuperLab response box ( with
multiple buttons ) is supposed to work with E-Prime, but I don't know of
anything in the voice-triggered input department. How difficult would it
be to create such a relay in a lab machine shop?

 

I have also read that Empirisoft ( makers of MediaLab software ) have
modified keyboards that will work with most PCs. These keyboards will
help register keypresses with 1 msec variablity, they claim. I have no
idea if this will work with E-Prime.

i can't speak to the microphone issue, but in our lab we use a USB
"Gravis Game Pad Pro", which looks just like a PlayStation controller.

you can find them on froogle for about $20.  you program the various
buttons to mimic keyboard buttons, so when you design your eprime
experiment you don't enable the response box device.  works like a
charm.

Hello,

I have a question about people's experience using response boxes and 
microphones with E-Prime.  My lab is considering using E-Prime for our 
stimulus presentation programs; the only hurdle at this point is the 
high cost of the PST Serial Response Box, for ourselves and for several 
collaborators we share our experiments with.

Our experiments require precise timings for voice-trigger and 
button-press input.  My question is, has anyone managed to use E-Prime 
with hardware other than the PST SR Box, particularly for voice-trigger 
input?  For instance, is it possible to use a standard microphone with 
a good sound card for voice triggers, or a cheaper gamepad for button 
input?

(PST tech support says such methods aren't supported, but I can't tell 
if that means they're difficult/impossible or only that the company 
prefers people to buy their hardware.)

Thanks for any ideas or insight!

Chris
