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. LEARN WITH SPEECH THERAPY STEP 4 - The only speech therapy app that rewards your child proportionally to the improvement of their articulation. - Uses scientifically proven video modeling for effective speech development. - Voice-activated functionality provides a fun, interactive learning experience. - The app basic version is completely FREE! - No ads. SCIENTIFICALLY-PROVEN LEARNING TECHNIQUES Speech Therapy Step 4 uses video modeling to create an immersive learning environment. When children watch model videos in real time, their MIRROR NEURONS are engaged. This is scientifically proven to be highly effective in speech development. FROM THE DEVELOPERS OF THE CLINICALLY-VALIDATED LANGUAGE THERAPY APPLICATION MITA Speech Therapy Step 4 is developed by Dr. A. Vyshedskiy, a neuroscientist from Boston University; R. Dunn, a Harvard-educated early-child-development specialist; MIT-educated, J. Elgart and a group of award-winning artists and developers working alongside experienced therapists.

Start learning the /s/ sound today with LispApp’s interactive exercises! LispApp is a mobile application designed to support speech therapy and to be used for practice at home. The app has been developed together with American speech-language pathologists. Both the content and structure follow effective methods used in speech therapy for practicing the /s/ sound. LispApp is suitable for children of all ages, from 3 years old up to the teenage years. However, we recommend that an adult and child use LispApp together – this way the adult can support the child when needed, while also spending quality time learning together. The structure of LispApp: Auditory bombardments – First, we learn what the /s/ sound is like. The child listens to many model words where /s/ appears in different positions. Listening for /s/ – Next, the child practices recognizing whether /s/ appears in a word or not. This strengthens awareness of the sound. Oral motor exercises – Then we practice tongue and mouth motor skills, making it possible to produce the /s/ sound at all. These exercises strengthen tongue control and airflow. Making the /s/ sound – Fourth, we start shaping the /s/ sound through the /t/ sound (t → tsss → s). This helps the child find the correct tongue placement and airflow. /s/ in syllables – After that, we move to syllable practice. The child works on using /s/ in simple syllables such as sa, si, su, as, is, us. /s/ in words – The final section is placing /s/ into words in different positions, as well as practicing common consonant blends. The app includes a variety of fun activities for practicing speech. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
