Articulation is the process by which sounds, syllables, and words are formed when your tongue, jaw, teeth, lips, and palate alter the air stream coming from the vocal folds. An articulation disorder involves problems making these sounds. Sounds can be substituted, left off, added or changed. Young children often make these speech errors. For example – they produce a “w” sound where it’s normally an “r” sound. So “rabbit” becomes “wabbit”. They may also omit sounds from words such as saying “nana” for “banana”. These errors may make it hard for people to understand and this may be an indication of an articulation disorder – especially if these errors continue past the expected age for normal development.
