I am attempting to set up an experiment in which the participant will be asked to determine which facial expression the actor is displaying. I am wondering if it is possible to use a normal microphone to detect the time in which the first time it recognizes a human voice when saying the word.
I also have the Cedrus rb410/rb610 response pad which does have a microphone activation feature. Is there any way to set this up, or do i need the SV-1 voice key?
Thanks a lot for your help.
