Soundsensor/ Voice Onset

Builder
1

Hi everyone,

I am building a picture naming experiment in PsychoPy 2026.1.3 on Windows.

The experiment shows pictures from a conditions file and records spoken responses. What I need is voice onset latency: the time between picture onset and the participant’s first vocal response.

I tried using the Sound Sensor component, but the experiment crashes with this error:

AttributeError: ‘SoundSensor’ object has no attribute ‘device’

The microphone component records audio correctly, but I need an automatic voice onset RT saved to the CSV file.

Is there a recommended way in PsychoPy 2026.1.3 to measure vocal onset RT in a picture naming task? Should I use a specific component, settings, or a Code Component?

Thanks!

Dear B_A,

Did you set the device to the physical microphone?

If it’s not listed in the drop down, go to the device manager in psychopy and add it
(press the usb symbol under “window”).
