What is visual biofeedback?
Various technologies can be harnessed to provide visual biofeedback for speech. Our lab is currently investigating the effectiveness of three types of real-time visual biofeedback for speech sound disorders, motor speech disorders, including Childhood Apraxia of Speech, accent reduction and voice disorders. The three types we focus on are ultrasound, visual-acoustic and electropalatographic (EPG) biofeedback.

Ultrasound Biofeedback
Ultrasound Biofeedback
An ultrasound probe held beneath the chin generates an image of the client’s tongue during speech. The client is directed to match an individualized tongue shape.

Visual Acoustic Biofeedback
Visual Acoustic Biofeedback
The client views a computer-generated acoustic representation (e.g., LPC spectrum) of his/her speech. The client is directed to match the visual representation of their speech to a target frequency pattern.

Electropalatographic (EPG) Biofeedback
Electropalatographic (EPG) Biofeedback
The client uses a pseudopalate, which registers and displays areas of contact between the client’s tongue and palate. The client is directed to match a target tongue-to palate contact pattern.
