Speech Therapy
Speech sound disorder in children
Clinically reviewed by Hannah Chamberlain
When a child's speech is hard to understand — sounds left out, swapped, or distorted — speech therapy is highly effective, especially early.

What a speech sound disorder is
A speech sound disorder means a child has ongoing difficulty saying speech sounds clearly, beyond what's expected for their age — sounds may be left out, swapped, or distorted, making speech hard to understand.[] Clinicians distinguish two broad types: articulation difficulties (physically producing a sound, like a lisp) and phonological difficulties (pattern-based, where whole groups of sounds are simplified).[] A child can have either or both.
Being hard to understand affects more than speech — it can frustrate a child, hold back social confidence, and, for phonological difficulties, has links to later literacy.
What it looks like
- Speech that's harder to understand than other children the same age
- Leaving sounds off words ("at" for "cat"), or swapping them ("tup" for "cup")
- Simplifying patterns — dropping ends of words, or fronting back sounds
- Frustration when not understood; giving up or avoiding talking
- Older children self-conscious about specific sounds
How speech therapy helps
Speech sound disorders are highly responsive to speech pathology. Australian speech pathologists typically draw on a toolkit of evidence-based approaches — minimal pairs, traditional articulation work, auditory discrimination, and cued articulation — matched to the child's specific error pattern.[] Most children with a diagnosed disorder need speech therapy to resolve it.[]
A typical plan includes:
- Assessment of the exact sounds and patterns affected
- Targeted therapy matched to articulation vs phonological difficulties
- Playful, high-repetition practice — sound change comes from doing, a lot
- Parent coaching so practice carries into everyday talk
NDIS funding
Whether a speech sound disorder meets NDIS access criteria depends on its severity and functional impact, and whether it's part of a broader, permanent condition. A speech pathologist's assessment supports any access request. If approved, speech therapy is funded under Capacity Building — Improved Daily Living. For families without NDIS funding, sessions are private-pay at the NDIS rate.
What a Hey Sprout session looks like
Sessions run online via secure video. Speech sound work is playful and repetitive — games and activities that get lots of practice of the target sounds. Parents are coached to weave short, frequent practice into everyday routines, where most of the progress happens. We hold your slot before asking for any NDIS details.
Frequently asked questions
My child is hard to understand — is that normal for their age?
Some unclear speech is normal in early childhood, and there are rough guides — most people can understand a 4-year-old most of the time. If your child is harder to understand than peers, frustrated by not being understood, or you're worried, a speech pathologist can assess whether it's developmental or needs support.
What's the difference between articulation and phonological problems?
Articulation problems are about physically making sounds (e.g. a lisp on "s"). Phonological problems are pattern-based — a child simplifies whole groups of sounds (e.g. dropping all sounds at the ends of words). The assessment tells them apart, and the therapy approach differs.
Is this the same as a language disorder?
No. Speech sound difficulties are about how clearly words are pronounced. Language disorder is about understanding and using words and sentences. A child can have one, the other, or both — the assessment sorts this out.
Will my child grow out of it?
Some speech sound errors resolve naturally; others persist and become harder to change with age. Early therapy gets the best results, so it's worth assessing rather than waiting and hoping.
Does Hey Sprout diagnose and treat this?
Yes — assessing and treating speech sound disorders is core speech pathology. We assess the specific error patterns and build a targeted, playful therapy plan, with parent coaching for practice between sessions.

Autism (Level 1 and Level 2) in children
Autism is a lifelong neurodevelopmental difference. Level 1 and Level 2 children typically benefit from speech, OT, and psychology support — and most are NDIS-eligible.
Cerebral palsy — therapy support for children
Cerebral palsy affects movement and posture. Goal-directed OT and speech therapy build independence and communication, online and coordinated with your team.
Childhood apraxia of speech (CAS)
CAS is a motor speech disorder where the brain struggles to plan the movements for speech. It needs frequent, specific speech therapy — and responds to it.
Down syndrome — therapy support for children
Children with Down syndrome thrive with early, consistent therapy. Speech and OT build communication and daily-living skills, online and parent-coached.
