AI Voices Fool Humans, But Brain Responses Differ

People struggle to distinguish between human and AI-generated voices, identifying them correctly only about half the time. Despite this, brain scans revealed different neural responses to human and AI voices, with human voices triggering areas related to memory and empathy, while AI voices activated regions for error detection and attention regulation. These findings highlight both the challenges and potential of advanced AI voice technology. Further research will explore how personality traits affect the ability to discern voice origins.
