Abstract
We can often ‘fill in' missing or occluded sounds from a speech signal—an effect known as phoneme restoration. Leonard et al. found a real-time restoration of the missing sounds in the superior temporal auditory cortex in humans. Interestingly, neural activity in frontal regions prior to the stimulus can predict the word that the participant would later hear.
