Goal: image stimuli should disappear when the voice/microphone onset starts - how?

Windows 10
PsychoPy version v.2021.2.3

Hey all :slight_smile: I have to create an experiment in which people see image stimuli for 5s each, they have to name it and I’m going to use their onset time. So far so good. BUT: is it possible to make the image disappear as soon as they start speaking, so with the voice onset?
I’m pretty sure there must be a possibility to set the stop time for the images as a condition…does anybody know how?
Thank you so much for your answers, hope you can help me :slight_smile:
