Spoken Cues to Deception
Speaker: Julia Hirschberg , Columbia University
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.
