Dysarthria is the most common speech disorder in children with Cerebral Palsy. Therefore, the study aimed to verify the effectiveness of a speech program based on improving basic speech processes to reduce the severity of Dysarthria among children with Cerebral Palsy. To achieve the goal of the study, the study relied on the Semi-Experimental approach. Divided into an experimental sample and a control sample, each of which consists of 10 children with Dysarthria associating with Cerebral Palsy, making sure that their mental abilities are intact, and making sure that they have an internal language that the researcher relies on in conducting the study. The study relied on a set of tools: The advanced progressive matrices scale, the diagnostic scale for Dysarthria associating with Cerebral Palsy, and the speech program based on improving basic speech processes to reduce the severity of Dysarthria among children with Cerebral Palsy, The program was implemented in 60 sessions, 3 sessions per week for a period of 5 months. The study sample, and all study hypotheses are fulfilled. This confirms the effectiveness of the speech program based on improving basic speech processes to reduce the severity of Dysarthria among children with Cerebral Palsy.
