Clinically reviewed by Hannah Chamberlain
Speech delay means a child's speech sound development is behind the typical age-based milestones. Many children catch up with the right early support.

What speech delay looks like
A speech delay is when a child's speech sound development falls noticeably behind what's typical for their age. This isn't the same thing as a language delay, though the two often overlap. A child with a speech delay can usually understand what's said to them — the gap is in producing clear, age-appropriate sounds.[]
Speech delay is one of the most common reasons families come to Hey Sprout. Most children referred for early intervention are between 2 and 6.
When to seek a speech pathologist
Pediatric speech pathologists in Australia look at a few signal flags. A child might benefit from an assessment if, by age 2, they aren't combining two words; by age 3, strangers have trouble understanding most of their speech; or by age 4, certain sounds (like k, g, f) still aren't emerging.[][]
These aren't hard cutoffs. Variability is normal. But waiting "to see if they catch up" past these points is the most common regret families share with us.
How NDIS funding works for speech
If your child has an NDIS plan, speech therapy is typically funded under either Capacity Building — Improved Daily Living or Capacity Building — Early Childhood (for children under 9).[] You can use Hey Sprout if your plan is self-managed or plan-managed. NDIA-managed plans can also be supported with a few extra steps — we'll walk you through it during intake.
What a Hey Sprout speech session looks like
Sessions run online via secure video. For young children, a parent or carer is in the room; for older kids, sessions can be one-on-one. The first session focuses on assessment — identifying which sounds are emerging, which are off-track, and what's most likely driving it. From there your therapist builds a short, focused plan with practice ideas you can use between sessions.
Most families see meaningful change in 8–12 sessions, though some children need more — and some less.
What to bring to the first session
A quiet space, a working camera and microphone, your child's NDIS plan number (if you have it handy), and any prior reports from a GP, pediatrician, or daycare.
Frequently asked questions
At what age should I see a speech pathologist?
If your child isn't combining two words by age 2, strangers struggle to understand most of their speech by age 3, or they aren't producing sounds like k, g, or f by age 4, an assessment is worth booking. These aren't hard cutoffs — variability is normal — but they're the most reliable signal flags.
How is a speech delay different from a language delay?
A speech delay is about producing sounds clearly. A language delay is about understanding and using words and sentences. A child can have one without the other, but they often co-occur. An assessment will tell you which is going on for your child.
Is speech therapy covered by NDIS?
Yes, when a child has an NDIS plan, speech pathology is typically funded under Capacity Building — Improved Daily Living, or Capacity Building — Early Childhood for kids under 9. Hey Sprout supports self-managed and plan-managed plans directly, and NDIA-managed plans with a few extra steps.
How many sessions does my child need?
Most children with a speech delay show meaningful progress within 8 to 12 sessions, though some need more and some less. Your speech pathologist will share an estimate after the first assessment session.
Can speech therapy work online?
Yes. Online speech pathology is well-evidenced for children from around age 3, and especially effective when a parent or carer is in the room for younger kids. Most Hey Sprout sessions are online.

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.
