People are not very good at distinguishing between human voices and voices generated by artificial intelligence (AI), but our brains do respond differently to human and AI voices, according to research presented today (Tuesday) at the Federation of European Neuroscience Societies (FENS) Forum 2024. The study was presented by doctoral researcher Christine Skjegstad, and carried out by Ms Skjegstad and Professor Sascha Frühholz, both from the Department of Psychology at the University of Oslo (UiO), Norway. We already know that AI-generated voices have become so advanced that they are nearly indistinguishable from real human voices.
It's now possible to clone a person's voice from just a few seconds of recording, and scammers have used this technology to mimic a loved one in distress and trick victims into transferring money. While machine learning experts have been developing technological solutions to detect AI voices, much less is known about the human brain's response to these voices." Christine Skjegstad, Department of Psychology, University of Oslo The research involved 43 people who were asked to listen to human and AI-generated voices expressing five different emotions: neutral, angry, fear, happy, pleasure [2].
They were asked to identify the voices as synthetic or natural while their brains were studied using functional magnetic resonance imaging (fMRI). fMRI is used to detect changes to blood flow within the brain, indicating which parts of the brain are active. Th.
