Dyslalia

Dyslalia is the incapacity to produce speech phonetically correctly in a language based on articulation organ anatomy disorders, without neurological disorders, and without hearing disorders. The impairment is brought on by incorrect lessons learned during the speaking process, but neither the condition of the central nor peripheral nervous systems is abnormal. Dyslalia has a variety of etiologies, including environmental factors, improper imitation of articulating patterns, persistence of errors made during articulation, and effects on the articulation of vision abnormalities.

Causes
Although there are several possible causes for dyslalia, the majority of cases seem to have something to do with immature neurons and speech-related processes.

Epidemiology
Dyslalia is more common in boys than in girls, with greater evidence of the condition in boys between the ages of five and seven.
