Phono Learning Center (PLC) is a research-based speech therapy app designed for children with phonological or sound-system disorders. Based on the evidence-based Cycles Approach, PLC helps children who are highly unintelligible improve their sound production through engaging and structured activities. Created by a certified speech-language pathologist trained in the Cycles technique, PLC combines effective intervention strategies with motivating, child-friendly games that make therapy fun and productive. Evidence-Based and Flexible PLC follows the principles of Barbara W. Hodson’s Cycles for Phonological Pattern Remediation, using carefully selected target words that support correct co-articulation and facilitate speech development. The app can be used with a true Cycles framework or easily customized for traditional articulation therapy. Designed for Individual or Group Sessions PLC allows multiple players in one session, automatically tracking each child’s performance. Clinicians can collect detailed data on multiple utterances without losing time on manual scoring, making it an ideal tool for busy speech-language pathologists. Engaging Activities That Motivate Learning Each activity encourages repeated practice of target words at the word, phrase, or sentence level: • Auditory Bombardment: Tap balloons to hear target words and improve listening skills. • Hot-Air Balloon: Say a target word, drag it into the basket, and watch the balloon lift off. • Matching Game: Strengthen memory and production through a fun matching activity. • Basket Paper: Say the word, crumple the paper, and toss it into the basket for points. • Puzzle Game: Reveal a picture piece-by-piece by saying each target word correctly. Comprehensive Data Collection PLC includes two data collection options: • Standard Scoring: Correct, Almost, or Missed. • Level of Prompts: Prompted, Imitated, or Independent. Each session report includes percentage accuracy, targets, session duration, and scoring method. Data can be printed, emailed, or exported to the Therapy Report Center app for efficient progress monitoring and reporting. Homework and Home Practice PLC provides printable and emailable homework sheets for each target area, allowing for consistent practice between therapy sessions and at home. Features • Based on the Cycles Approach by Barbara Hodson • Four fun and motivating games • Word, phrase, and sentence levels • Individual and group data tracking • Customizable scoring systems • Compatible with Therapy Report Center • Supports literacy with printed text • Homework for each target area • Developed by Mary Huston, MS, CCC-SLP Professional Reviews “Instead of adapting apps to meet evidence-based strategies, PLC was built around them.” — The Speech Room News “It’s more engaging than most articulation apps, with real flexibility for Cycles therapy.” — Busy Bee Speech Empower Communication Through Play Phono Learning Center transforms research-based intervention into interactive learning. Designed for professionals, loved by kids, and trusted by SLPs worldwide.
