The LinguiSystems Articulation Test (LAT) App for iPad is intended for use by certified speech-language pathologists to assess articulation disorders. A comparison study showed no statistical difference when comparing iPad versus paper administration. This app is:
The LAT App was designed to identify children and young adults with abnormal articulation patterns. It ensures a thorough examination of all sounds and blends by presenting several sounds more than one time in the same position. All positions at the word level are tested.
Test results, in combination with the stimulability and intelligibility ratings and a Childhood Apraxia of Speech Screening included with the LAT App, allow the SLP to make appropriate recommendations regarding the type and length of service. An accurate diagnosis leads to best practice therapy. The LAT App can also be used to measure progress in therapy.
The LAT App consists of five picture plates that assess all the consonant sounds in words, including initial blends. The vocalic /r/ is tested in multiple contexts. The Stimulability Assessment, administered immediately after an incorrect production is made, determines if the student is able to imitate a correct production.
The Intelligibility Rating Scale is based on the student's type and frequency of errors in single-word productions and helps you determine the type and severity of the speech-sound disorder. The LAT App is easy to administer, score, and interpret. (©2012)
