Children with articulation disorders can be known to delete sounds, substitute sounds, add sounds, or distort sounds.
There is no exact cause of articulation disorder. Several factors like hearing loss, illness, developmental disorders, neurological disorders, or genetic orders could all be causes of an articulation disorder.
Physical differences in the mouth can also (but not always) have an effect on a child’s articulation. Some examples are:
Ankyloglossia: tongue tie, this is when the flap of skin under your tongue is too short.
A cleft lip or palate.
Over bite: top teeth extend past bottom teeth
Under bite: bottom teeth extend past top teeth.
Open bite: Teeth do not fully close when mouth is at rest.
Crossbite: Lower jaw is to the right or left of upper jaw.
A sign of articulation disorder can be if relatives or strangers can only understand a child less than 75% of the time.
While young children often make speech errors, it becomes a disorder when these errors continue past a certain age of development.
