What technology offers visual feedback for training correct oral articulation placements?

Electropalatography is a technology used to provide visual feedback to individuals who are training on correct oral articulation placements. It works by using a splint that contains sensors which detect the contact between the tongue and the tongue blade or the hard palate during speech. This contact information is displayed in real time, allowing both the speech-language pathologist and the client to see and monitor how the tongue is moving in relation to the roof of the mouth while producing speech sounds. This immediate feedback can be exceptionally beneficial for individuals who need to adjust their articulation, making it a valuable tool in speech therapy.

The other options, while related to speech, do not provide the same level of visual feedback regarding articulation placements. A nasometer is primarily used to assess nasal resonance and airflow during speech rather than oral placements. A stethoscope is designed to listen to sounds inside the body and is not utilized in speech therapy contexts for feedback on articulation. See-Scape™, which is often associated with assessing nasal vs. oral airflow or resonance, also does not offer the specific visual feedback on tongue placement that electropalatography provides.
