Tongue Movements May Influence Speech Motor Learning

When we speak, although we may not be aware of it, we use our auditory and somatosensory systems to monitor the results of the movements of our tongue or lips. This sensory information plays a critical role in how we learn to speak and maintain accuracy in these behaviors throughout our lives. Since we cannot typically see our own faces and tongues while we speak, however, the potential role of visual feedback has remained less clear.
