Based on the child's unique phonetic/phonemic inventory and stimulable sounds, a small set of specific words/phrases is created and used to improve motor planning/programming through practice. Principles of motor learning support increased practice, including increased sessions and practice of targets during sessions. DTTC offers a hierarchy of support for the child to learn and practice accurate movements through direct imitation, simultaneous production, slowed rate, and other visual/tactile cues as needed. Feedback gives the child information about accuracy and how to change their movement for accurate production, reducing the rate and type of feedback over time. AAC is simultaneously introduced to increase functional communication and decrease frustration while the child improves verbal communication.
