These are difficulties in pronouncing certain phonemes (letters), due to a phonological problem, immature articulation forms, an anatomical limitation or a problem at the CNS or PNS level.
Phonological disorder is the inappropriate production of the sound as a whole (in a word, sentence, etc.) that can be observed within normal vocabulary and grammar.
It is the systematic alteration in the pronunciation of a certain phoneme, resulting from the persistence of immature articulation forms.
It is a disorder of non-neurological central origin and caused by physical lesions or malformations of the peripheral articulatory organs.
