Speech sound disorders, speech sounds and parts of speech (phonotactic rules that determine syllable shape, structure, stress and prosody) occur at one or all levels of phonological representation, perception and motor production and
Removing speech sounds is called articulation. Incorrect production of the origin, form, timing and pressure of these sounds is defined as articulation disorder. For example, the individual uses 'Key' instead of 'Bird'; 'Ayaba' instead of 'car'; He might say 'song' instead of 'song'. Individuals with articulation disorders fail to reproduce sounds in isolation or in phonetic contexts.
Phonological disorder is the difficulty in acquiring organizational knowledge of speech sounds, which forms the basis of the grammatical rules of the language. In individuals with phonological disorders, the displacement of various speech sounds (eg, saying /kipat/ /truck/ instead of /kipat/ /kamon/), lowering them (eg: /op/ instead of /top/), changing sounds (/eyebrow) Confusion or misuse of word phrases (such as saying /kace/ instead of /) is observed. Errors in the speech of children with this problem may be inconsistent. Individuals with phonological disorders may produce a sound in one word and incorrectly produce the same sound in another word. For this reason, it is extremely difficult to understand the speech of individuals with phonological disorders. Children with phonological disorders can write letters as they say when they write.
