Articulation is the production of speech sounds. Speech sounds are created by movements of the articulators (lips, tongue and jaw) and the vocal cords.

An articulation disorder is the mispronunciation of speech sounds and may include sound omissions, substitutions, distortions and additions. Children should be able to produce all speech sounds correctly by age 8. However, if an articulation disorder is present and not addressed, it may persist into adulthood.

Articulation disorders differ from phonological disorders, but they can occur together.

Treatment for articulation disorders focuses on teaching the difference between correct and incorrect productions, correct placement of the articulators and practicing the sound in words, sentences and ultimately, spontaneous speech.
