Which structure is visible using ultrasound in speech therapy?

• A. Pharyngeal walls
• B. Soft palate
• C. Tongue
• D. Hard palate

Answer: (C)

In ultrasound imaging for speech therapy, the primary thing you can see clearly is the tongue. The tongue sits just beneath the oral surface and moves a lot during speech, making it accessible to high-frequency ultrasound and easy to track in real time. This allows clinicians to visualize its shape, position, and movement during different sounds, providing useful biofeedback for articulatory therapy. The hard palate, being bone, doesn’t show up well with ultrasound because bone reflects and blocks the sound waves. The soft palate and pharyngeal walls lie deeper and often behind air spaces, which makes them harder to image reliably with standard clinical ultrasound. That’s why the tongue stands out as the structure visible in this context.
