Articulation refers to the movement of speech mechanisms such as the tongue, lips, larynx, teeth, hard palate, nose, etc., These mechanisms may not work properly due to being weak, damaged, or malformed, which causes a speech sound disorder.
On the other hand, phonological disorders focus on the predictable rule-based errors in speech. An example of a phonological disorder is the repeated “fronting” of our velar sounds /k/ and /g/ and are replaced with the sounds /t/ or /d/.
Refer to the Little Bee Speech for a full list of phonological disorders and an approximate age these errors are eliminated.
