HERE’S HOW IT WORKS: Minimal Pairs Therapy, an evidence-based approach for helping children with speech difficulties, is at the heart of this app. This approach helps kids learn to say sounds correctly by contrasting words that differ by just one sound, e.g., "tea," "key." This speech language pathology (SLP) app covers each step of minimal pairs therapy: 1) Familiarization with the pictures and word meanings 2) Auditory discrimination (the ability to hear the difference between the sounds in words) 3) Production (saying the words). ● Select the category and choose the sounds you want to target in initial or final position of the word ● Use Flashcards to familiarize the child with the pictures and word meanings ● Work on auditory discrimination by playing Whack-a-Mole, Feeding Time, Balloon Pop, Fishing or Road Trip ● Play Stamp and Say, Coin Drop, Splashdown, Four in a Row or Raft Race to work on speech production. ● Record the child and play it back for instant feedback and self-monitoring. ● Adjust the word selection and other options to keep your therapy at the right level. ● Email the results to a parent or other adult user. Once you’re ready for the full experience, simply purchase all categories. It takes lots of repetition to master speech sounds—and that’s how we can help. Minimal Pairs Arcade makes it easy to get lots of speech practice done while keeping children motivated and engaged.
