Elevate your speech therapy practice with the Articulation Assessment Toolkit Plus (AAT Plus)—the most comprehensive, dynamic, and intuitive criterion-referenced articulation assessment designed specifically for Speech-Language Pathologists. Whether you are determining baselines, monitoring progress, or writing highly targeted IEP goals, the AAT Plus transforms complex speech sound data into clear, actionable clinical insights. Moving far beyond simple raw scores, this tool provides a multi-dimensional analysis of your student's speech sound production, right from your iPad. KEY CLINICAL FEATURES Comprehensive Assessment Modules Quick Consonant Screener: Rapidly assess all English consonants in initial, medial, and final positions. Full Assessment: Evaluate all consonants plus a comprehensive Vowels Analysis (Singletons, Diphthongs, Tongue Advancement/Height, and Lip Rounding). Specialized R-Screener: Tackle the complex /r/ phoneme with a dedicated module targeting prevocalic /r/, vocalic /r/ (ar, er, ear, etc.), and R-blends. Features specialized visual badging for distortions ("dis") and gliding ("gl"). Sentence Screener: Evaluate connected speech to identify coarticulation errors and patterns that only appear in continuous dialogue. Advanced Analytics Dashboard Instantly view detailed color-coded breakdowns of your student's speech sound breakdown across six critical categories: Position in Word: Initial, Medial, and Final. Manner of Articulation: Fricatives, Plosives, Nasals, Glides, etc. Place of Articulation: Bilabial, Alveolar, Velar, Palatal, etc. Voicing Features: Differentiates voiced vs. voiceless consonant accuracy. Word-Level Breakdown: A complete phonetic transcript of target words, highlighted errors, and clinical notes. Error Types & Phonological Processes: Automatically identifies active error patterns (e.g., Final Consonant Deletion, Cluster Reduction) and provides built-in developmental suppression ages. Dynamic Stimulability Testing Automatically imports all missed targets from your assessment into an interactive stimulability dashboard. Test isolated sounds and specific word positions with built-in auditory/visual modeling prompts. Watch target statuses update in real-time (Untested, Stimulable, Not Stimulable) to effortlessly select your next therapy targets. Developmental Sound Profile Instantly overlay your student's assessment data onto standard developmental acquisition norms (adapted from Sander, 1972). Perfect for parent consultations to visually demonstrate whether an error is developmentally appropriate or requires intervention. Professional Reporting & Exporting Generate beautiful, multi-page PDF clinical reports with a single tap. Capture subjective Intelligibility Ratings (Single Word & Conversational) via intuitive sliders. Add custom clinical recommendations directly to the final report. Seamlessly share via Apple AirPrint, Email, or export directly to the Smarty Ears Therapy Report Center (TRC). Why SLPs Love AAT Plus: While standardized tests are required for initial eligibility, the AAT Plus is your essential companion for functional treatment planning. Because it is a criterion-referenced tool, you can use it continuously for progress monitoring, dynamic assessment, and baselining without the validity restrictions of standardized tests. Empower your clinical decision-making and streamline your report writing with the AAT Plus!

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.
