Self‐Supervised App‐Based Speech Training for Children With Speech Sound Disorder—A Single‐Case Experimental Design Study

What is already known on this subject To achieve high-enough intervention dose, home-training is often an important part of intervention for speech sound disorder (SSD). This is not always easy for families to attain, however, and digital speech training games may offer an attractive alternative or complement. What this paper adds to existing knowledge By tracking four children's usage and speech production over three weeks of playing a speech training game at home, the paper shows that the current version of the game and the implemented intervention delivery are not sufficient to promote more accurate production of targeted speech sounds. What are the potential or actual clinical implications of this work? Before recommending the speech training game for children with SSD, changes are recommended both with regard to the design of the game itself (e.g., refining the feedback provided in the game) and to the intervention delivery (e.g., increasing parental involvement).
