Articulation Disorder

An articulation disorder refers to errors in speech sound production including deletion of sounds, substitution of sounds, adding sounds, or distorting sounds. It is appropriate for children at certain ages to produce sounds in error; however, if a child is producing an error with a sound that they should have acquired, they may have an articulation disorder. Articulation disorders may negatively impact a child’s speech intelligibility when communicating with peers and adults. There is a range of typical speech-sound development, though most children are 90% intelligible to a wider range of communication partners by age 4.
