There are several approaches for children with articulation delays. If the delay appears to be caused by muscle weakness, an oral-motor approach is typically used. This approach uses various exercises to strengthen the muscles in the jaw, lips and tongue. A phonological approach focuses on the child’s ability to hear the difference between sounds, learn the “rules” for each sound and then be able to reproduce that sound in words, phrases and sentences. Children with apraxia demonstrate difficulty coordinating muscle movements in order to consistently produce speech sounds. Therapy for these children involves various approaches including (but not limited to) systematic drill work, PROMPT, and the Kaufman Method.
