Articulation refers to the correct production of speech sounds. Articulation errors occur due to faulty placement, timing, direction, pressure, speed or integration of the movement of the lips, tongue, velum, palate and pharynx.
There are several common articulation errors which include:
- Additions-the insertion of a sound not part of the word itself Ex: puhlease for please
- Distortions-the sound is acceptable for listeners but is produced incorrectly. Ex: s is slushy or sounds like it is coming out of the sides of the mouth
- Omissions- is the absence of a sound Ex: painer for painter
- Substitutions-is the replacement of one speech sound for another Ex: thoe for shoe
