If your child is not talking as much as other children their age, you are probably asking yourself whether you should be worried — or whether they will simply catch up on their own. It is one of the most common concerns raised by South African parents, and it is exactly the right question to ask early.
The short answer is this: early assessment is always better than waiting. A paediatric speech therapist in Johannesburg can identify whether your child has a speech delay, what is causing it, and what the most effective treatment path looks like — before the gap gets wider.
What Is a Speech Delay?
A speech delay means a child is not meeting the expected communication milestones for their age. This can involve how clearly they speak (articulation), how many words they use, how they put sentences together, or how well they understand what others are saying.
Speech delay is different from a language disorder, though they can occur together. A speech delay is about the rate of development — the child is on the same path but moving more slowly. A language disorder involves the way language is being processed or structured.
Both are treatable. Both respond best to early intervention.
Signs of Speech Delay by Age
Every child develops at their own pace, but the following milestones are generally expected. If your child is consistently missing several of these, a speech delay assessment in Johannesburg is worth booking.
By 12 months
- Babbles using a variety of sounds (ba, da, ma)
- Responds to their name
- Uses gestures like pointing or waving
- Says one or two recognisable words
By 18 months
- Uses at least 10 to 20 words consistently
- Points to pictures in books when named
- Understands simple instructions
- Tries to imitate words they hear
By 2 years
- Uses 50 or more words
- Combines two words (“more juice”, “daddy go”)
- Strangers can understand at least half of what they say
- Follows two-step instructions

- Asks and answers a wide variety of questions
What Causes Speech Delay in Children?
Speech delay does not usually have a single cause. The most common contributing factors include:
- Hearing loss — Even a mild or temporary hearing loss from ear infections can significantly affect speech development. A hearing assessment is often the first step in a speech delay evaluation.
- Oral-motor problems — Difficulties with the tongue, lips, or jaw can affect how clearly sounds are produced.
- Multilingual environments — Children growing up with two or more languages at home may take slightly longer to develop fluency in each language, but should not be significantly delayed across all of them.
- Limited language exposure — Children who do not hear a lot of spoken language at home, or who spend long periods with screens rather than conversation, may develop language more slowly.
- Developmental conditions — Conditions such as autism spectrum disorder, Down syndrome, or cerebral palsy often include speech and language challenges.
- Prematurity — Babies born prematurely may reach milestones slightly later than full-term peers.
A qualified speech therapist in Johannesburg will assess all relevant factors during an evaluation, not just the speech itself.
When Should You Book a Speech Delay Assessment?
You do not need to wait until your child is behind by years. A speech delay assessment in Johannesburg is appropriate any time you have a concern. Here are the clearest signals that it is time to act:
- Your child is not meeting the milestones listed above for their age group
- Your child loses skills they previously had (regression is always worth investigating)
- Your child is consistently frustrated when trying to communicate
- Family members or teachers have raised concerns
- Your child’s speech is not improving over a two to three month period
- Other children the same age seem significantly more verbal
If you are in any doubt, book the assessment. A good speech therapist will either confirm there is an issue and start treatment, or reassure you that your child is developing well. Either outcome is valuable.
What Happens During a Paediatric Speech Therapy Assessment in Johannesburg?
An assessment at a paediatric speech therapy practice like Speak Clearly is thorough but relaxed. It is designed to feel like play for the child while giving the therapist the information they need.
A typical assessment includes:
- Parent intake discussion — You will be asked about your child’s developmental history, home language, health history, and the specific concerns you have noticed.
- Formal standardised testing — Age-appropriate assessments that measure vocabulary, sentence structure, sound production, and language comprehension against South African norms where available.
- Informal observation — The therapist watches how your child communicates during structured play and interaction, which often reveals patterns formal tests do not capture.
- Hearing screening — A basic hearing check is included where indicated, because hearing ability directly affects speech development.
- Feedback and recommendations — At the end of the session, you receive a clear explanation of findings and a recommended plan.
You will leave knowing exactly where your child stands and what the next steps are.
What Does Speech Delay Treatment Involve?
Speech delay treatment in Johannesburg typically combines structured therapy sessions with activities and strategies you continue at home. The frequency and format depends on the severity of the delay and the child’s individual needs.
Therapy is play-based, especially for younger children. Sessions are engaging, purposeful, and tied to communication goals that your therapist tracks and adjusts over time. Parents are actively involved — what happens between sessions makes a significant difference to outcomes.
Most children with speech delays who receive early treatment show meaningful progress. The earlier intervention begins, the better the results.

Frequently Asked Questions
At what age should I be concerned about speech delay?
Any time your child is consistently missing milestones for their age group, it is worth booking an assessment. As a general guide: if your child has fewer than 10 words by 18 months, is not combining words by 24 months, or is not being understood by strangers by age 3, a speech therapist should evaluate them.
Will my child just catch up on their own?
Some children do catch up without intervention, especially early talkers who are slightly late. However, relying on “wait and see” is a risk. Children who receive early therapy consistently make faster and more complete progress than those who wait. If there is a concern, an assessment costs nothing more than the time — and the information it gives you is valuable either way.
Can speech delay be caused by too much screen time?
Excessive screen time can contribute to slower language development because it replaces face-to-face interaction, which is how children learn to communicate. Screens do not cause speech disorders, but reducing passive screen time and increasing back-and-forth conversation is one of the most effective home strategies for supporting language growth.
Is speech delay the same as being a late talker?
A late talker is a child, typically between 18 and 30 months, who has delayed expressive language (fewer words than expected) but shows normal comprehension and social development. Many late talkers do catch up, but around 25% go on to have persistent language difficulties. A speech therapist can assess which category applies and whether monitoring or treatment is appropriate.
Does growing up with two languages cause speech delay?
Bilingualism does not cause speech delay. Bilingual children may produce fewer words in each individual language, but their total vocabulary across both languages is typically on par with monolingual peers. If a child is behind in all languages, not just one, that is when assessment is needed.
What is the difference between a speech delay and a speech disorder?
A speech delay means the child is developing language in the typical pattern but more slowly than expected. A speech or language disorder involves a disruption to the typical developmental pattern itself — such as phonological disorders, language processing difficulties, or conditions like childhood apraxia of speech. Both are assessed and treated by speech therapists, and both respond well to early intervention.
How long does speech therapy take for a child with a speech delay?
Duration depends on the severity of the delay, the child’s age at the time treatment starts, and how consistently therapy strategies are carried over at home. Some children make significant progress in three to six months. Others with more complex needs may need ongoing support for a year or more. Your speech therapist will give you a realistic estimate after the assessment.
