Speech Sound Disorders: Early Signs and Treatment Options

Speech sound disorders occur when children have difficulty producing speech sounds correctly or fluently. The NIDCD reports that about 7.2 % of children aged 3–17 have voice, speech or language disorders. Speech sound disorders are most common in children aged three to six, with around 10.8 % affected. By first grade, approximately five per cent of children have noticeable speech sound disorders. Common disorders include articulation disorders (difficulty making particular sounds), phonological disorders (patterns of sound errors) and motor speech disorders such as childhood apraxia of speech.

Early signs of speech sound disorders include substituting one sound for another (“wabbit” for “rabbit”), omitting sounds (“pane” for “plane”) or distorting sounds. Children may have difficulty being understood by unfamiliar listeners, become frustrated when misunderstood or avoid speaking. While some errors are typical at certain ages (for example, using “w” for “r” up to age six), persistent errors beyond expected ages warrant assessment.

Speech‑language pathologists diagnose speech sound disorders through comprehensive evaluation. Assessment includes evaluating oral structures and motor skills, listening to the child’s speech in different contexts, analysing patterns of errors and considering the child’s hearing and language skills. Sometimes a hearing test is recommended to rule out hearing loss.

Treatment depends on the type and severity of the disorder. Therapy may focus on teaching the correct placement and movement of the articulators (lips, tongue and jaw), practising target sounds in syllables and words, and gradually increasing complexity to sentences and conversation. For phonological disorders, treatment might emphasise teaching sound patterns and contrasts rather than individual sounds. In motor speech disorders, therapy often targets planning and coordinating movements and may include rhythm or tactile cues.

Parents can support treatment by practising exercises at home. Read books that highlight target sounds, play games that emphasise sound discrimination and use visual cues or mirrors to help your child see how sounds are produced. Be patient and positive; avoid constant correction and instead model correct pronunciation in a natural way.

Children with speech sound disorders often make significant progress with intervention. Early identification is crucial; the longer a child practises incorrect patterns, the harder they are to change. If you suspect your child has a speech sound disorder, consult a speech‑language pathologist for an assessment and tailored therapy plan.
