Sensory basis of speech motor learning and memory

Changes to speech offer a quantifiable means to assess speech motor learning, and the resulting memory is thought to be motor in nature. Here, we evaluate this idea and show instead that memory for speech movements has a sensory basis. Speech motor learning, using altered auditory feedback, provides an experimental model to address this question as it involves auditory, somatosensory, and motor components to learning. Transcranial magnetic stimulation was used to disrupt auditory (superior tempo
