Researchers from Tianjin University and the Chinese University of Hong Kong found that while listeners often fail to consciously distinguish real human speech from synthetic AI voices, their brains begin to tag subtle acoustic differences after brief exposure. Using EEG caps, the study revealed early neural responses that separate real and AI speech within milliseconds, highlighting a gap between unconscious perception and conscious decision‑making. The findings suggest the auditory system is already adapting to AI‑generated voices, offering hope for future tools that could help people translate these neural cues into reliable detection of deepfake audio.
