*** This is the FREE version of Clusters Complex Pro. This version includes /shr-/ and five themes. *** The full version, Clusters Complex Pro features: • CC and sCC clusters (/θr-/, /fl-/, /fr-/, /sl-/, /shr-/, /str-/, /skr-/, /spr-/, /skw-/, /spl-/) • English targets – Words (88) – Phrases (440) – Sentences (440) • Colorful photos and videos • Over 30 themes (sports, animals, activities) for students to choose from; each comes with its own customized buttons, backgrounds, and reward videos • Randomization option • Self-monitoring • Progress monitoring • Customized messages for students • Data collection features include audio recordings which can be emailed, backed up to computer, or stored on your Apple device Welcome to the Clusters Complex! Our app targets the ten most complex clusters, including three-element clusters and complex two-element clusters. It includes 968 photographs depicting 88 words, 440 phrases and 440 sentences. Children may select motivating themes based on specific animals, activities and sports. A randomization option presents the photographs in mixed order. Furthermore, children can engage in self-monitoring and view short reward videos if they achieve a high level of accuracy. SLPs have the option to monitor progress through recordings and data collection over time, all of which can be backed up on a computer or emailed. All words in this app were carefully selected for the above complex clusters. Ideally, the targets also include early-developing sounds in the medial or final word position. For instance, among /skw-/ words are “squad,” “squeaky” and “squeeze.” We did not select “square” or “squabble” because the final sounds may distract from the challenging initial clusters. Additionally, the phrases and sentences were judiciously chosen. As much as possible, they are loaded with early-developing sounds so that the child may focus on the cluster target. For example, the /fl-/ phrase “white floppy hat” allows the child to focus on the /fl-/ target because it is surrounded by the early sounds, /w t p h/. Likewise, the /fl-/ sentence “We took a flight to Maine” provides a facilitative context.

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. This app can be used in therapy to target: ● Articulation ● Apraxia ● Phonological Awareness & Disorders ● Minimal Pairs ● Speech Perception for Deaf and Hard of Hearing HEAR FROM OUR USERS Join the growing community of users who praise Minimal Pairs Arcade!
