AB  - The recognition of human speakers by their voices is a remarkable cognitive 
      ability. Previous research has established a voice area in the right temporal 
      cortex involved in the integration of speaker-specific acoustic features. This 
      integration appears to occur rapidly, especially in case of familiar voices. 
      However, the exact time course of this process is less well understood. To this 
      end, we here investigated the automatic change detection response of the human 
      brain while listening to the famous voice of German chancellor Angela Merkel, 
      embedded in the context of acoustically matched voices. A classic passive oddball 
      paradigm contrasted short word stimuli uttered by Merkel with word stimuli 
      uttered by two unfamiliar female speakers. Electrophysiological voice processing 
      indices from 21 participants were quantified as mismatch negativities (MMNs) and 
      P3a differences. Cortical sources were approximated by variable resolution 
      electromagnetic tomography. The results showed amplitude and latency effects for 
      both MMN and P3a: The famous (familiar) voice elicited a smaller but earlier MMN 
      than the unfamiliar voices. The P3a, by contrast, was both larger and later for 
      the familiar than for the unfamiliar voices. Familiar-voice MMNs originated from 
      right-hemispheric regions in temporal cortex, overlapping with the temporal voice 
      area, while unfamiliar-voice MMNs stemmed from left superior temporal gyrus. 
      These results suggest that the processing of a very famous voice relies on 
      pre-attentive right temporal processing within the first 150 ms of the acoustic 
      signal. The findings further our understanding of the neural dynamics underlying 
      familiar voice processing.
