Speech and language therapy – Articulation and phonological disorder

A single sound made by a single letter of combination of letter is called a Phoneme. A child or an adult is expected to reproduce the correct sound that they have heard. Some of them may have difficulty is reproducing some particular sounds. When a child or an adult is not pronouncing the word correctly, then those around them have a difficulty in understanding them resulting in miscommunication and misunderstanding.

While Articulation disorder refers to the correct reproduction of the sound heard, phonological disorder refers to a pattern of errors in speech. The child with the phonological disorder may shift the sounds within a word, or may replace one sound with another. This makes is much more difficult to understand the child. A child which is having difficulty in reproducing a sound may also drop the sound from the word thus totally producing a different word than intended.
