Created by a speech-language pathologist, Score 4 Articulation makes speech practice fun, motivating, and effective. This innovative articulation app combines the excitement of a classic game with targeted speech sound practice to help children improve their articulation skills. Whether you're an SLP looking for a powerful speech therapy tool or a parent supporting speech at home, Score 4 Articulation is a game-changer. KEY FEATURES: Engaging Gameplay: Enjoy the classic challenge of connecting four in a row, now with a twist! Each turn begins with practicing a speech sound, making articulation practice an integral part of the game. Speech Mastery Through Play: Players can tap on each word to hear a clear pronunciation model. A visual counter tracks repetitions to encourage frequent practice and build speech accuracy. Targeted Sound Practice: Choose from a variety of game boards, each focusing on different sounds, including R (initial, vocalic, blends), S (initial, blends, final), L (initial, medial, blends), SH (initial, medial + final), CH (initial, final), J (initial, medial + final), and TH (voiceless). Target words have been meticulously selected by a speech-language pathologist, and a clear pronunciation model can be heard aloud by tapping on the image. Multiple Modes and Levels: Challenge the computer in single-player mode or play against a friend, SLP, or parent in two-player mode. Select from easy to difficult levels to suit the student’s skill level. Two players can even choose different sound targets, making it ideal for mixed speech groups. Rewards and Motivation: Win a game and color in three stars. Every 10 repetitions also earns stars or diamonds, helping kids stay engaged and motivated to practice more. Research-Based: Research suggests that massed practice, with many repetitions in a short period, enhances speech sound acquisition and motor learning (Maas et al., 2008; Bislick et al., 2012). This game leverages this principle to help children improve their speech more effectively. Score 4 Articulation turns speech therapy practice into a game kids will love. Download now to help your child or students make meaningful progress through play.
