Abstract : Gating of sensory information around the onset of movement is a characteristic of a range of voluntary behaviors. For speech, the amplitude of auditory cortical potentials is reduced during speech production, the so-called speech induced suppression. However, it is unknown whether somatosensory processing (or perception) is also suppressed during speech production. The current study focused on somatosensory event-related potentials (ERPs) associated with facial skin deformation and examined whether the somatosensory ERPs are changed during speech production tasks. Specifically, we investigated changes in the magnitude of somatosensory ERPs during speech posture with and without voicing together with changes associated with different speech utterances.
