Visual feedback of the tongue influences speech adaptation to a physical modification of the oral cavity. The Journal of the Acoustical Society of America , 2021; 150 (2): 718 DOI: 10.1121/10.0005520 ...

One group received visual feedback of their tongue with a sensor under their chin oriented to provide an ultrasound image within the sagittal plane (a slice down the midline, front to back).

Visual feedback is just as important as a sense of body position when it comes to the involuntary reflexes that activate muscle movement, says a new study in the open-access journal eLife.
