Neuromagnetic responses were recorded to study their relationship to the omission of the second sound in triplet of speech sounds. The responses were separately averaged by standard, deviant and omission. In the omission response, a component related to the omission of the speech sound was observed over the right and/or left hemispheres in five out of six subjects, although its amplitude was very weak. In the subtracted waveforms, enlarged components were observed in the latency of 258-702 msec referenced to the onset of the second sound of the standard stimuli. Equivalent Current Dipole (ECDs) of the components were estimated in the right hemisphere of two subjects and in the left hemisphere of one subject.
