Phonological Therapy targets the reduction of phonological processes by helping children reduce the production of errors on sound blends, the omission of initial and final consonants in words, or sound substitutions, to assist in clear speech production. A phonological process is a normal pattern in which all children simplify adult speech. However, as a child ages, these processes should begin to disappear.
Phonological therapy is aimed at correcting errors in sound production. There are several evidence based treatments which target the reduction of the processes which are retained past an approriate age.
