Spoken Cues to Deception

Speaker: Julia Hirschberg , Columbia University
Date: April 8 2008
Time: 11:00AM to 12:00PM
Location: 32-G575 Stata Center
Host: Regina Barzilay, MIT CSAIL

This talk will discuss production and perception studies of deceptive speech. A large corpus of deceptive and non-deceptive speech was collected to identify acoustic/prosodic and lexical cues associated with deception. I will discuss machine learning experiments to predict deception, which achieve performance comparing favorably with the performance of human judges on the same data and task. Current findings on the role of personality factors in deception detection will also be described.

In collaboration with Frank Enos, Columbia University; Elizabeth Shriberg, Andreas Stolcke, and Martin Graciarena, SRI/ICSI; Stefan Benus, Brown University.
