An articulation disorder involves problems making sounds. Sounds can be substituted, left off, added or changed. These errors might make it difficult for a child to be understood by others and impact social interactions, school participation and academics (ex. Reading, writing, phonological awareness skills). Many children make speech errors, so factors such as age range in which children develop each sound is used when determining if sound errors are age-appropriate. If the articulation errors continue past the age that they are expected to be correct, the child may have an articulation disorder. Speech therapy for an articulation disorder will focus on the specific sound(s) with which a child is having difficulty.
