Hello,
I try to realize some voicekey functionality (RT measurement of voice onset time) with Builder.

First I tried the microphone component. According to the help page the data tab contains:
Speaking Start/Stop Times: bool
Save onset/offset of speech.

I thought that would give me the necessary data, but unfortunately the microphone component does not have anything similar to Speaking Start/Stop Times: bool
Save onset/offset of speech.

Next I tried to use some coding and tried using psychopy.voicekey.OnsetVoiceKey. Unfortunately, even the import
import psychopy.voicekey as vk gives an error message saying that the module pyo could not be found.

Any idea where I can find some documentation on how to realize a voicekey in Builder. That would be very helpful.

Thanks in advance - Sven
