Alternatives to SRBox for voice-trigger?

[Christopher Maloof]

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
