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: pipeline.zip
The readme file contained therein has a list of the YouTube videos used, and the pipeline.sh script can be used to download and process them.
Pipeline.sh 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 pipeline.sh 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)stanford.edu with any questions!
