The model of auditory feedback processing for speech proposed by Houde & Nagarajan (2007). It is based on an internal model of feedback generation that includes a model of the vocal apparatus and a model of feedback loop delays incurred by motor responses and sensory feedback processing. If the expected speech sound from the internal model closely matches the actual speech sound, the prediction error is small, which is seen as small activity in auditory cortex. However, if the actual speech sound does not match the prediction, there is a greater prediction error and thus greater activity in auditory cortex.
