Prof. Karl Schaller, Giannina Rita Iannotti, Pavo Orepic and many more studied the Spatiotemporal Patterns Underlying Self-other Voice Discrimination. During their research, they combined psychophysics, voice-morphing technology, and high-density EEG to identify the pattern.
With 26 healthy participants, both with air-and bone-conducted stimuli, they found a self-voice-specific EEG topographic map occurring around 345 ms post-stimulus and activating a network involving insula, cingulate cortex, and medial temporal lobe structures. Specifically, the better participants performed at SOVD task, the less frequently they activated this network.
