In a study conducted by the University of Zurich, researchers have discovered that the human brain can naturally detect deepfake voices.
This study, published in Communications Biology, sheds light on how the human brain processes natural voices differently than deepfakes, revealing the brain's inherent ability to recognize these artificial sounds.
The study involved 25 participants who were tasked with distinguishing between natural and deepfake voices. Researchers used advanced voice-synthesizing algorithms to create high-quality deepfake voices from recordings of four male speakers.
The participants listened to multiple voices and were asked to determine whether the identities of two voices were the same, either matching two natural voices or one natural and one deepfake voice.
The results showed that deepfake voices were correctly identified two-thirds of the time, indicating that while deepfakes have the potential to deceive, they are not foolproof.
