By rearranging these structures, you alter the acoustical properties of your vocal tract, allowing you to create over 200 distinct sounds, or phonemes.
Humans vocalize by forcing air over the various structures of the vocal tract, including vocal folds, tongue and lips. This is not Morgan Freeman, but if you weren’t told that, how would you know? Organic vs. To detect audio deepfakes, we and our research colleagues at the University of Florida have developed a technique that measures the acoustic and fluid dynamic differences between voice samples created organically by human speakers and those generated synthetically by computers. These voice-only communications greatly expand the possibilities for attackers to use deepfakes. To detect deepfakes, many researchers have turned to analyzing visual artifacts-minute glitches and inconsistencies-found in video deepfakes.Īudio deepfakes potentially pose an even greater threat, because people often communicate verbally without video-for example, via phone calls, radio and voice recordings. Deepfakes have brought with them a new level of uncertainty around digital media.
The voice he heard was that of an audio deepfake, a machine-generated audio sample designed to sound exactly like his boss.Īttacks like this using recorded audio have already occurred, and conversational audio deepfakes might not be far off.ĭeepfakes, both audio and video, have been possible only with the development of sophisticated machine learning technologies in recent years. The voice on the other end of the call was not his boss. The worker sits back in his chair, takes a deep breath, and watches as his boss walks in the door.
