****The jungle/safari theme is adorable! The kids loved the board game and all wanted to land on the hippo and the snake. I like the multiple ways to target the processes. (Carries Speech Corner)**** ****If you choose the Game Board option, you get to have some fun in the jungle!! My students are always asking if we are playing the jungle game each time I pull out my iPad! This app is great for data collection and sharing information with parents and teachers! (Kristin C., SLP and blogger)**** The Phonological Processes app was created by a certified speech and language pathologist for children ages 4 and up who exhibit phonological disorders or delays. This research-based app implements a linguistic approach for treatment of phonological disorders by engaging users in minimal pair contrast therapy. Children will have fun drilling with flashcards while playing a colorful animated board game full of surprises. In addition, children can record their productions and compare them with the targeted productions pre-recorded in this app. Phonological Processes app includes the most common phonological processes in the following activities: -Auditory bombardment with minimal pairs -Auditory discrimination with minimal pairs -Minimal pair production -Single word production Phonological processes addressed in this app include the following : -Affrication -Deaffrication -Cluster reduction (with “ L”) -Cluster reduction (with “R”) -Cluster reduction (with “S”) -Cluster reduction (mixed) -Final consonant deletion -Fronting -Gliding (with “L”) -Gliding (with “R”) -Gliding (mixed) -Prevocalic voicing -Stopping of fricatives -Stopping of affricates -Stopping (mixed) The Phonological Processes app is easy to navigate and allows users to employ several tools to perform the following tasks: -Enter multiple students -Change settings and use randomization -Select auto-scoring -Select alternate counts for multiple students -Track correct and incorrect responses -E-mail results at the end of the session Background Phonological processes refer to typical patterns that are used by children to simplify their speech. For example, a young child may say “tar” for “car” or “may” for “make.” Phonological processes are very common among three- and four-year-old children, but most of them should spontaneously resolve by approximately age 5. If phonological processes do not disappear by this age, the child may need formal speech evaluation and intervention. Treatment of Phonological Disorders The Phonological Processes app employs minimal pair contrast therapy. The minimal pair approach to phonological remediation teaches children the function of sounds, emphasizing that changing sounds changes the meaning of a word (Barlow & Gierut, 2002). Minimal contrast therapy targets pairs of words that differ only by one sound. It may focus on the perception of contrast or production of contrast. In the perception task, the child is asked to point to target words when presented with two or more pictures (minimal pairs). In the production task, the child is asked to verbally produce minimal pairs (Bernthal and Bankson 1998). REFERENCES Barlow, J. A., and Gierut, J. A. (2002).

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.
