If your child struggles to be understood, has difficulty putting sentences together, or seems behind their peers when it comes to talking, you are not alone. Speech and language difficulties are among the most common developmental concerns in young children, and getting the right support early can make a real difference.
In this post, we break down the most common speech disorders seen in children, explain the difference between a speech delay and a speech disorder, and outline when it may be time to see a Speech Pathologist.
What Is a Speech Disorder?
A speech disorder occurs when a child has ongoing difficulty producing sounds, words, or sentences clearly enough for others to understand them. This is different from a language disorder, which relates to how a child understands or uses words to express ideas.
It is important to know that both can exist separately or at the same time. For example, a child may pronounce words clearly but have trouble forming full sentences. Another child might use long sentences but be very hard to understand because of how they produce certain sounds.
Around 8 to 9 per cent of young children experience speech sound disorders, and by the time they reach primary school, roughly 5 per cent still have noticeable difficulties with speech.
Speech Delay Versus Speech Disorder: What Is the Difference?
A speech delay means a child is developing their speech skills in the right order, just at a slower pace than expected. Many children who are considered “late talkers” will catch up over time, sometimes with support and sometimes on their own.
A speech disorder, on the other hand, means the pattern of speech development is not following the typical sequence. The difficulties tend to be more persistent and may not resolve without professional intervention.
Understanding this distinction matters because it shapes what kind of support your child needs and how urgently they need it.
Common Speech Disorders in Children
1. Articulation Disorder
An articulation disorder happens when a child has trouble placing their tongue, lips, or jaw correctly to produce certain sounds. This can result in sounds being substituted, left out, or changed. For instance, a child might say “wabbit” instead of “rabbit” or drop the ending sounds of words entirely.
Most children master the full range of speech sounds by age four to five. If a child continues to have trouble producing specific sounds beyond this age, an assessment by a Speech Pathologist is recommended.
2. Phonological Disorder
While similar to an articulation disorder, a phonological disorder involves predictable patterns of sound errors rather than difficulty with individual sounds. A child might consistently replace one type of sound with another, such as saying “tat” instead of “cat” or “do” instead of “go.”
These patterns are a normal part of early speech development, but when they persist past the expected age, they can significantly affect how well a child is understood by teachers, peers, and unfamiliar listeners.
3. Childhood Apraxia of Speech
Childhood Apraxia of Speech is a motor-based speech disorder where the brain has difficulty planning and coordinating the muscle movements needed for speech. A child with apraxia knows what they want to say, but the message between the brain and the mouth gets disrupted.
This condition is rare, affecting approximately one to two children per thousand in Australia. It is a lifelong condition that does not resolve on its own and requires intensive, ongoing Speech Pathology intervention. Children diagnosed with Childhood Apraxia of Speech may be eligible for National Disability Insurance Scheme funding to support their therapy.
4. Stuttering (Fluency Disorder)
Stuttering is a disruption in the flow of speech. It can present as repetitions of sounds or words, prolonged sounds, or blocks where a child appears to get “stuck” before a word comes out.
Many young children go through a brief period of typical disfluency as they learn to talk, and this often resolves within a few months. However, if stuttering continues for more than six months, begins after the age of three, or is causing your child noticeable frustration or avoidance, a Speech Pathology assessment is a good next step.
5. Language Delay
Although not technically a speech disorder, language delay is closely related and is one of the most common reasons families seek Speech Pathology support. A child with a language delay may have a smaller vocabulary than expected for their age, struggle to follow instructions, or find it hard to put words together into sentences.
Language delays can affect both how a child expresses themselves (expressive language) and how they understand what others are saying (receptive language). Early intervention before the age of three is linked with significantly better outcomes for children experiencing language difficulties.
When Should You Seek Help?
There is no need to wait for a formal diagnosis before reaching out. If you have noticed any of the following, it is worth speaking with a Speech Pathologist:
Your child’s speech is hard for others to understand at an age when it should be clearer. They seem frustrated when trying to communicate. They are not meeting expected speech and language milestones. A teacher, childcare worker, or family member has raised concerns. Stuttering is affecting their confidence or willingness to speak.
Early support gives children the best opportunity to develop strong communication skills, which flow into literacy, social connection, and confidence in the classroom and beyond.
