Do you or others have difficulty understanding what your child is saying?

February 6, 2019

Do you have difficulty understanding what your child says when he/she is talking to you?

Do your child’s grandparents, siblings, peers, or unfamiliar listeners have difficulty understanding your child as well?

Does your child seem frustrated when you ask him/her to repeat what he/she has said?

Does it seem like your child has a lot to say but at times their speech is difficult to understand?

If so, your child may be presenting with symptoms consistent with a phonological disorder. Below is a quick guide to what a phonological disorder is, signs of a phonological disorder, and information about the diagnoses and treatment.

What is a phonological disorder?

It is common for children to make mistakes when they are learning new words. However, if mistakes continue past a certain age and include phonological processes (the organizing of sound patterns) a phonological disorder may occur. It is important to note that every sound has a certain range of ages when a child should produce the sound correctly. This means that phonological processes are normal up until a certain age.

Signs of a phonological disorder (in children)

  • Difficulty being understood by familiar & unfamiliar listeners (decreased intelligibility). Included below is a helpful chart from Flipsen (2006) in determining intelligibility in young children. For example, at 1 year of age 25% of what a child says should be intelligible, or understood, by strangers.

Age 1;0

25% intelligible to strangers

Age 2;0

50% intelligible to strangers

Age 3;0

75% intelligible to strangers

Age 4;0

100% intelligible to strangers

  • Phonological processes that persist past a certain age
    • Phonological processes occur when children attempt to simplify adult phonological patterns. Phonological processes are developmentally appropriate and predictable. However, as stated above, they become problematic when they occur past a certain age.
  • Substituting sounds in words - For example, when the word cup à t This is an example of “fronting”, where a child who has difficulty producing sounds in the back of his/her mouth moves the sound to the front because it’s easier for them to produce.
  • Omitting sounds in words - For example, when the word star à _ This is an example of cluster reduction, where a child takes away one of the sounds in the word because it is easier for them to produce.

Who can diagnose & treat a phonological disorder?

Speech-language pathologists diagnose & treat phonological disorders. During the assessment process, the therapist would administer a questionnaire/conduct a parent interview, administer a standardized sound assessment, perform an oral mechanism exam, and conduct a play-based assessment to listen to your child’s conversational speech.

If a child is diagnosed with a phonological disorder, a speech-language pathologist can create an effective intervention plan tailored in response to your child’s errors.   Therapy would focus on auditory bombardment (inputting the target sound/patterns to the child via auditory methods), feature awareness (teaching the child the idea of the features needed for the child to make a system change), and production of the target sound/pattern during structured and unstructured activities. Treatment outcomes should increase your child’s ability to be understood by multiple communication partners and target the correct formation of sounds.
