Articulation Disorder (speech sounds are substituted, deleted, added or distorted )
An articulation disorder means that a sound or a few sounds are not being produced correctly at the age of typical development. It is caused by difficulty getting the speech helpers (front/back tongue, lips, teeth, nose, upper ridge, front/back roof, and vocal cords) to form the sounds. This can affect the clarity of speech. If your child says /p/ when he/she is trying to say /b/, the lips are doing the correct action, but the client isn't turning on the voice. Or if the person says "dot" for "dog" they are moving the tongue to the front of the mouth when it should be /g/ made in the back of the mouth.
The individual learns to produce English sounds correctly with the use of videos, flashlights, mirrors, visual aids, modeling and other tools and techniques while participating in fun and engaging activities.
