Evaluating the Efficacy of Opti-Speech, a 3D Visual Feedback System, for Speech Treatment

The purpose of this study is to determine if feedback from a three-dimensional real-time visualization of the tongue, a program called Opti-Speech, can be used to improve speech.

Participants will be asked to complete the Goldman Fristoe Test of Articulation along with several other assessment tests. Then speech treatment, guided by Opti-Speech, will be provided to the participant for up to 10 treatment sessions. The participant will be asked to come back after the final treatment for a 2-month follow-up assessment.
