Mac 12.6.2 OS (Monterrey)
PsychoPy version: 2022.2.4
We’re having issues successfully running experiments in which verbal responses are recorded via microphone. Here’s a bit of background…
We present visual (e.g., a picture, a word) or auditory (e.g., a sentence or a piano melody) stimuli to participants for them to name into a microphone. We use a webcam connected via USB-C to a mac mini to audio record trials.
We have a separate microphone connected to a device that converts an utterance by the participant into a key press. That key press (equivalent to hitting the 0 key) is used as a trigger to record response time on each trial. We don’t ‘force end of routine’ when the button is pressed because that would prevent PsychoPy from recording the utterance via the webcam microphone.
Attached please find a 5-trial picture naming experiment that gives you an overview of how we collect verbal responses.

We’re having persistent issues recording audio and saving microphone responses. Our experiments will crash randomly and audio responses will not get saved out. Others have had this issue and have documented the problem here, for example:
It appears that a short-term fix is to open PsychoPy via the terminal. Others have noticed their experiments don’t crash when using this ‘version’ of PsychoPy. Unfortunately this option does not fix our issue. We still find that experiments will crash randomly. It would appear this is specific to microphone recording because we run button-press tasks and get good data consistently.
Is there a way, at minimum, to save trial-level data in real time? I’m wondering if we could at least get the data generated prior to a crash. It’s better than nothing at all. Any pointers/tips would be much appreciated.
Thanks in advance,
