One of the most common questions parents ask is, “Should my child be saying that sound yet?” It’s natural to compare your child’s speech with other children, but speech sound development is a gradual process, and every child develops at their own pace.
Some sounds are easier for children to produce and develop earlier, while others take longer to master. Knowing what is typical can help you understand when to seek advice from a speech pathologist.
The short answer
Children do not learn every speech sound at the same time. Simpler sounds usually develop first, while more complex sounds may continue developing into the early school years.
What’s most important is how well your child can be understood, rather than whether every sound is perfect.
If your child’s speech is difficult for others to understand or you’re concerned about their speech development, a speech pathology assessment can help.
How do speech sounds develop?
Speech develops over many years as children learn to coordinate their lips, tongue, jaw and breathing to produce different sounds.
Children usually:
- Babble before saying words.
- Learn easier speech sounds first.
- Gradually develop clearer speech.
- Continue refining speech throughout preschool and the early primary school years.
Speech development is not a race. There is a wide range of typical development.
Typical speech sound development
While every child is different, children generally begin using sounds in this order.
Around 1–2 years
Children often use earlier-developing sounds such as:
- M
- B
- P
- N
- D
- H
- W
Words may still be simplified. For example:
- “Nana”
- “Mama”
- “Ball”
- “Bye”
This is a normal part of learning to talk.
Around 2–3 years
Many children begin producing:
- T
- K
- G
- F
- Y
Speech becomes easier for familiar adults to understand, although unfamiliar listeners may still have difficulty understanding some words.
Around 3–4 years
Children continue developing:
- L
- J
- CH
- SH
Some speech errors are still expected during this stage.
Around 4–5 years
Many children are becoming easier for unfamiliar people to understand.
More complex sounds continue to develop, including:
- V
- S
- Z
Some children may still be learning these sounds, which can be within the typical range.
Around 5–7 years
The later-developing sounds often include:
- R
- TH (as in thumb and this)
- ZH (as in measure)
Some children continue refining these sounds during the early primary school years.
How clear should my child’s speech be?
As a general guide:
- Around 2 years: Parents and familiar adults understand much of what their child says, although unfamiliar listeners may find speech difficult to understand.
- Around 3 years: Familiar adults understand most of the child’s speech, and unfamiliar listeners understand more of what is said.
- Around 4 years: Most of a child’s speech should be understood by both familiar and unfamiliar listeners.
If your child is frequently difficult to understand beyond these ages, it may be helpful to seek advice from a speech pathologist.
What are speech sound errors?
As children learn to speak, they often simplify words.
For example, they might:
- Leave sounds out (“ca” instead of “cat”)
- Replace one sound with another (“tat” instead of “cat”)
- Simplify longer words
Many of these patterns are a normal part of development and gradually disappear as children grow.
However, if these patterns continue beyond the expected age or significantly affect intelligibility, assessment may be recommended.
When should I see a speech pathologist?
Consider seeking advice if your child:
- Is difficult for unfamiliar people to understand.
- Becomes frustrated when communicating.
- Is not producing many different speech sounds.
- Continues using speech patterns that don’t seem to be improving.
- Is avoiding talking because others don’t understand them.
- You are concerned about their speech development.
You don’t need to wait until your child starts school. Early support can help children develop clear, confident communication.
How can I support speech development at home?
You can encourage speech by:
- Talking together throughout the day.
- Reading books regularly.
- Singing songs and nursery rhymes.
- Modelling words clearly without asking your child to repeat them.
- Expanding on what your child says.
- Keeping communication fun and pressure-free.
Children learn best through positive, responsive interactions with the important people in their lives.

Frequently Asked Questions
Is it normal for my child to pronounce words incorrectly?
Yes. Many speech errors are a typical part of development as children learn new speech sounds. The type of error and your child’s age help determine whether the pattern is expected or whether further assessment is recommended.
When should my child be able to say the “R” sound?
The “R” sound is one of the later-developing speech sounds and may continue developing into the early primary school years.
Should I correct my child’s speech?
Rather than asking your child to repeat words correctly, it’s often more helpful to model the correct pronunciation naturally.
For example:
Child: “Tat!”
Adult: “Yes, it’s a cat! The cat is sleeping.”
This provides a clear model without creating pressure.
Do I need a referral?
No. Speech pathologists are first-contact practitioners, so you can book an assessment without a referral. If you’re eligible for Medicare or NDIS funding, our team can also discuss your funding options.
