Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percent articulatory accuracy	Sound probe lists will be administered within 30 minutes of treatment. Probe lists will be scored as correct or incorrect. The percentage of probes correct will be calculated	within 30 minutes of treatment
Secondary	Change in Accuracy of Speech Sound Production from Pre-Treatment to Post-Treatment	The Goldman Fristoe Test of Articulation will be administered prior to any speech treatment with Opti-Speech and again 2 months after the final speech treatment session. The percentage of consonants correct (PCC) will be used to assess the change in accuracy of speech sound production from pre-treatment to post-treatment	Immediately prior to first speech treatment and 2 months after final treatment.
