In this paper, we explore the hypothesis that multimodal features as well as demographic information can play an important role in increasing the performance of automatic lie detection. We introduce a large, multimodal deception detection dataset balanced across genders, and we analyze the patterns associated with the thermal, linguistic, and visual responses of liars and truth-tellers. We show that our multimodal noncontact deception detection approach can lead to a performance in the range of 60%–80%, with different modalities, different genders, and different domain settings playing a role in the accuracy of the system.
