Abstract
A video is classified as real or fake by extracting facial features, including facial modalities and facial emotions, and speech features, including speech modalities and speech emotions, from the video. The facial and speech modalities are passed through first and second neural networks, respectively, to generate facial and speech modality embeddings. The facial and speech emotions are passed through third and fourth neural networks, respectively, to generate facial and speech emotion embeddings. A first distance, d, between the facial modality embedding and the speech modality embedding is generated, together with a second distance, d, between the facial emotion embedding and the speech emotion embedding. The video is classified as fake if a sum of the first distance and the second distance exceeds a threshold distance. The networks may be trained using real and fake video pairs for multiple subjects.
