Progressing after 5 seconds of silence, is it possible?

Michelle

Hi

I’m afraid I’ve little experience with OpenSesame it’s on my to do list. I’m wondering is it possible to do the following with it?

Present a word
The participant will then talk about the word
Then I want to display the next word 5 seconds after the participant stops talking

So the next word is displayed after 5 seconds of silence. I don’t need it to record the participants responses that will be done externally. I have a Cedrus sv-1 voice key which I could use for voice input.

Many Thanks
Michelle

Hi Michelle,

This should be possible. There have been similar threads over time, like this one http://forum.cogsci.nl/index.php?p=/discussion/6/solved-voicekey-input-triggering-responses-through-sound-input/p1

A quick glance suggests that you can indeed process recorded audio on the go, use thresholds etcetera. I think it would be best to continuously collect audiosamples (with a duration of, say, 3000ms) in a while loop (python syntax, using an inline_script item, see http://osdoc.cogsci.nl/python/). You then want to break from the while loop when the last collected audiosample didn't pass a certain threshold (due to silence).

Cheers,

Thanks so much for that Josh will spend some time on coming to grasps with it.
