Testing whether voicekey was triggered

Dear all.

I am using the integrated voicekey to get RTs for voice responses. I saw in a previous discussion that it is impossible to continue to the next trial based on a voicekey response/trigger, so I am asking participant to press the ENTER after they have given a response. The question is whether it is possible to make sure the voicekey was triggered is some way, when participants press the ENTER (i.e., to prevent ‘no-response’ trials).

Thanks in advance!

Hi Isaac, did you ever figure this out? Thanks!
