Phonological disorder

A phonological disorder refers to a speech sound issue observed in children deviating from the normal trajectory of speech development. These children may exhibit sound inaccuracies not typical in the speech progression of their peers who are developing typically.Our speech and language therapists can assess your child’s speech skills to identify what speech errors your child is making as well as the impact of these errors on your child’s communication skills. Our speech and language therapists use the information from the assessment to create a therapy programme that works on removing atypical speech errors identified in your child’s assessment as well as increasing the overall clarity of your child’s speech.

Speech and language therapy can help your child to produce speech that can be understood by others by reducing and removing their use of non-developmental phonological errors as well as delayed developmental phonological errors.

What is a phonological disorder?

A phonological disorder occurs when a child struggles to understand the sound system and the rules surrounding speech. This is usually something most children achieve naturally, however children with a phonological disorder may need therapy to be taught how to use their sound system appropriately. Children who have a phonological disorder may produce a sound or some sounds correctly in one word but then struggle to produce the same sound or sounds in other words. Some children may say the ‘s’ in sun but struggle to produce the ‘s’ in pass.

There are two types of phonological disorders:

Consistent phonological disorder

The child presents with phonological errors that are idiosyncratic (specific to the child) or unusual and are not seen in typically developing children. The child may also present with delayed developmental phonological errors that are not typical for their age range.

Inconsistent phonological disorder

The child presents with phonological errors that are unusual, or idiosyncratic (specific to the child), as well as possible delayed developmental phonological errors. In addition to this the child’s production of single words shows high variability, for that reason the child may produce one word in many different ways.

A phonological error (process) is the name given to error patterns or simplifications of speech used by children in speech development. Many phonological processes are developmental and are normal part of speech development. As a child’s speech matures and develops these phonological errors start to fade out and eliminate. If a child presents with these errors 6 months after they should have eliminated the child may have a phonological delay. A child who has a phonological disorder may present with a phonological delay as well as unusual or idiosyncratic (specific to the child) phonological errors.

Developmental phonological errors

Developmental phonological errors are error patterns in children’s speech that are normal and occur as part of the speech development process. These error patterns start to fade out as children get older and their speech sound repertoire increases. Developmental phonological errors include:

  1. Reduplication
  2. Consonant harmony
  3. Context-sensitive voicing
  4. Devoicing
  5. Fronting
  6. Final consonant deletion
  7. Cluster reduction
  8. Weak syllable deletion
  9. Stopping
  10. Gliding

Impact of a phonological disorder

A phonological disorder can impact a child’s speech and other aspects of their life, for example:

Unintelligible speech.

Increased chances of being misunderstood by others.

Difficulties with social aspects of life that require speech.

Possible difficulties with literacy and reading skills.

Increased frustration.

Reduced confidence levels.

May require longer to respond and produce speech.

Long term impact on social, academic and vocational well being.

Our speech and language therapists can help children who have a phonological disorder by providing a therapy programme that works on increasing their intelligibility to others. Our speech and language therapists aim to create a therapy programme that can be implemented across the child’s communicative settings.
