This page keeps the code used for the experiments in the paper:

   Rob Voigt, Robert J. Podesva and Dan Jurafsky. 2014. Body Movement Correlates with Prosodic Indicators of Engagement. Proceedings of Speech Prosody 7.

It is available here:

The readme file contained therein has a list of the YouTube videos used, and the script can be used to download and process them. is a bash script that assumes a Unix build (Linux or OSX should be okay); it has dependencies on python, ffmpeg, sox, pafy, and praat. Python, ffmpeg, and sox should be callable from the command line; you should edit the variables in to point to the locations of pafy and praat.

The code will not be maintained, but please feel free to contact us at robvoigt(at) with any questions!
