Federation of European Neuroscience SocietiesJun 26 2024 People are not very good at distinguishing between human voices and voices generated by artificial intelligence , but our brains do respond differently to human and AI voices, according to research presented today at the Federation of European Neuroscience Societies Forum 2024.
Participants correctly identified human voices only 56% of the time and AI voices 50.5% of the time, meaning they were equally bad at identifying both types of voices. However, looking at the brain imaging, researchers found that human voices elicited stronger responses in areas of the brain associated with memory and empathy . AI voices elicited stronger responses in areas related to error detection and attention regulation .
"While we are not very good at identifying human from AI voices, there does seem to be a difference in the brain's response. AI voices may elicit heightened alertness while human voices may elicit a sense of relatedness."
