The developer of the only clinically-validated language therapy application MITA that was downloaded by over 3 million families, brings you a series of Speech Therapy apps: Speech Therapy Step 1 – Preverbal exercises Speech Therapy Step 2 – Learn to sequence sounds Speech Therapy Step 3 – Learn to say 500+ words Speech Therapy Step 4 – Learn to say complex words Speech Therapy Step 5 – Record your own model words and exercise articulation Speech Therapy Step 4 is for children who already learned many words and want to exercise on their articulation. HOW IT WORKS? Speech Therapy Step 4 uses 1000+ prerecorded video exercises. These videos encourage children to mirror words’ pronunciation. A proprietary AI algorithm measures similarity between model words and children’s vocalizations. Improvements are rewarded with reinforcers and PlayTime. This technique was demonstrated to improve speech production in toddlers, late talkers (speech delay), children with Apraxia of Speech, Stuttering, Autism, ADHD, Down Syndrome, Sensory Processing Disorder, Dysarthria. Video exercises are followed by a PlayTime. Improvements in performance are rewarded with reinforcers and a longer PlayTime. In order to achieve a longer PlayTime, children try to improve their articulation. In this way the app works autonomously all the time encouraging children to improve articulation.
