Can AI help my child’s speech delay? What it can do and what it can’t

If you’re worried about your child’s speech, you are absolutely not alone. Many parents I work with tell me the same thing:

‘I’ve been Googling…’
‘I asked ChatGPT what activities to try…’
‘TikTok said we should practise this sound every day…’

It makes complete sense. When waiting lists are long, evenings are quiet, and your child is struggling to communicate, it’s natural to look for help wherever you can find it.

AI tools can actually be helpful in some ways. But they also have clear limits especially for children with significant speech delays or speech sound disorders.

Here’s an honest, balanced guide to what AI can do, and what it simply can’t.

✔️ What AI can help with

1. Explaining things in simple language

AI can be very helpful for explaining speech and language terms in a way that’s easy for parents to understand for example, what a phonological delay is, or what Childhood Apraxia of Speech means. It can also suggest possible reasons for a child’s speech delay based on the information you provide.

The difficulty is that parents (or teachers) can only ask questions based on what they notice or perceive to be the problem. In practice, this doesn’t always tell the full story. For example, parents often report that their child ‘can say certain words’, but during an assessment we may find those words are actually produced with consistent error patterns. These patterns give important clues about the underlying nature of the difficulty, whether it’s a delay or a disorder and they guide the speech therapist in choosing the most effective targets to improve intelligibility.

2. Suggesting games and activities

AI is very good at suggesting ideas for games and practice, such as word lists, simple play activities, sound practice games, book suggestions, and ways to encourage talking within everyday routines. These can be especially helpful when you feel stuck or want some fresh inspiration for supporting your child at home. It can help to think of AI as a big ideas bank, somewhere to dip into when you need new, playful ways to keep practice engaging.

3. Helping you prepare questions for a therapist

Some parents use AI to list questions before an assessment, understand reports and organise concerns.

This can make therapy feel less overwhelming and more collaborative.

Used this way, AI can actually support the therapy process.

❌ Where and why AI cannot replace real life speech therapy

There is substantial research supporting the effectiveness of real-life speech therapy compared to generic online resources or AI-generated suggestions. Here are some key points highlighting why in-person therapy is often more beneficial:

  • Personalisation: Speech therapists assess each child’s unique needs, strengths, and challenges through direct observation and interaction. This personalised approach allows for tailored interventions that address specific issues, which generic resources cannot provide.
  • Nuanced understanding: Therapists are trained to recognise subtle cues in speech production, including the nuances of sound articulation, language comprehension, and social communication. This expertise enables us to identify underlying issues that may not be apparent through generic assessments.
  • Motivational support: A speech therapist can provide encouragement, motivation, and emotional support, which can significantly enhance a child’s willingness to participate and engage in therapy. This relational aspect is crucial for building confidence and reducing anxiety around communication.
  • Evidence-based practices: As a highly trained and specialised speech therapist I utilise evidence-based practices that are grounded in research, ensuring that the techniques used are effective and up to date. This contrasts with generic online information, which may not always be reliable or validated.
  • Progress monitoring: In-person therapy allows for ongoing assessment and adjustments to the treatment plan. We track progress over time and modify strategies as needed, ensuring that the therapy remains effective and relevant.

Research studies consistently show that individualised, face-to-face interventions lead to better outcomes in speech therapy than generalised approaches. For parents and caregivers, seeking professional help tends to provide a more effective path toward improving their child’s communication skills.

The healthiest way to think about AI

AI works best as a starting point, not a substitute. You might use it to understand your child’s report and learn how speech develops,

But if your child has significant delay or difficulty being understood, what makes the real difference is:

  • A tailored assessment
  • A clear therapy plan
  • Expert target selection
  • Ongoing adjustment
  • Support for both child and you the parent!

Dear parents,

If you’ve been turning to AI for help, it doesn’t mean you’re doing anything wrong. It means you care!

But please know the best outcomes usually come from combining your daily support at home with guidance and support from your speech therapist who knows you and your child.

Many of my past and present clients tell me that they really value my ‘handholding’ and me guiding them in between the sessions. A quick check in is often all that is needed but it makes a huge difference!

If you’d like support or advice, please contact me and I can help guide the next steps.

    Unlocking communication: My daily life with the Saltillo 88 Core Board

    Introduction

    As an AAC speech and language therapist who uses the Saltillo 88 Core board every day, I can tell you it’s more than just a communication tool. It’s a doorway to independence, connection, and expressing my students’ unique voice.

    What is the Saltillo 88 and why do I use this one?

    In this blog post, I want to share practical, real-world examples of how I integrate the Saltillo 88 into various daily activities, empowering my students and parents to learn to communicate.

    There are literally hundreds of core boards out there and I have tried many different ones over the years. Which one should I use with this particular client? Should I make up my own? (I have made up tons!) or should I use a ready-made one like the one below which is what this blog is about.

    For me the best ones are boards with a good number of core words (at least 60) so that the board is versatile and can be used across a range of activities. The board needs to have a range of pronouns, verbs, descriptors, prepositions and question words to be useful and to stimulate not just requesting but commenting and asking questions. Another consideration is: can the board easily be transferred to a more robust AAC system. Once my student is used to the symbols and where they are could we move to an electronic talker/device. And if this answer is ’yes’ then we have a great board to get started with.

    Below is a picture of the Saltillo 88.

    Saltillo 88 Core Board
    Saltillo 88 Core Board

    It has 88 words and I find it really does suit most activities. The same board and design is also then found on the TOUCHCHAT AAC device which can be a seamless transition for our learner.

    Let me dive into how core words/board or AAC can be used daily:

    1.  Getting dressed

    Whilst choosing clothes for your little one and getting them ready for the day you can use the following words: want, like, get, finish. Always pack the words into little phrases you can speak naturally when using a board. I have tried to show you phrases that you could use below.

    The words in bold are the core words on the board and the other words are just words you say whilst pointing to the core word.

    • Goal: Express choices, needs, and preferences about clothing.
    • Ideas:
      • ‘I want this one [specific item of clothing: ‘shirt’, ‘pants’]’
      • ‘I like that one [colour/type of clothing]’
      • ‘Help me [put/get it on/take off]’
      • ‘let’s get your socks now’
      • finished let’s go’ (when dressed)

    2. Having a shower/bath

    • Goal: Bath time tends to happen daily and so it lends itself to using the same useful phrases and words to chat about temperature preferences, to ask for toys or for washing routines.
    • Ideas:
      • ‘let’s go have a bath/shower’
      • ‘let’s turn on the tap/water’
      • now turn it off
      • ‘let’s get/have more toys/water/bubbles/tickles’
      • all gone, what’s next?’
      • ‘how about washing your hands/feet’
      • ‘let’s do that again’
      • ‘need some help?’
      • Stop it now, let’s do something different’

    3. Mealtimes

    • Goal: Mealtimes can be (or should be) enjoyable and motivating to ask for specific things we like, and commenting about our eating experiences.
    • Ideas:
      • ‘I want/give me [food item: ‘apple’, ‘bread’]/[drink item: ‘water’, ‘juice’]’
      • More foods/drinks/snacks’
      • All done
      • ‘that’s messy we like that (not)’
      • ‘Like’/‘Don’t like’
      • Big’/‘Little’
      • ‘this is so nice!’

    4. Playing

    • Goal: This is where it’s at for children of course and we can use our core words to chat and engage with our little learners.
    • Ideas:
      • ‘I want play’
      • Go’/‘Stop
      • More/again’
      • ‘not it’s my My turn/’it’s Your turn
      • ‘that’s a Big one!’/‘let’s do Little bubbles (describing toys)
      • ‘let me Open it for you (for boxes, doors in play)
      • ‘I See it’ (to draw attention)
      • Help me’ (with a tricky toy)

    5. Opening boxes/doors/etc

    • Goal: Most kids love opening boxes, doors and cabinets to see what there is to play with. Help your child to ask for what they want.
    • Ideas:
      • let’s Open that box/bag/zip/door’
      • get me a (toy) out of here’
      • ‘Let’s Take it out and see what it is?’
      • finished’ (when finished with the task)
      • ‘I want [what’s inside]’
      • ‘What’s next? Let’s see’

    Tips for using AAC effectively

    • Consistency is key: Emphasise using it regularly, even for small things.
    • Modelling: this is crucial, the adults need to use the board for all situations first and foremost before we can expect our child to be interested.
    • Patience: Communication takes time and practice.
    • Celebrate successes: Acknowledge every communicative attempt.
    • Make it accessible: Keep the board within easy reach at all times.

    Conclusion

    If you’re considering the Saltillo 88, or TouchChat, or are already using it, I hope these examples inspire you. It’s a journey of discovery, and every word communicated is a step towards a more connected and independent life. What are your favourite ways to use the Saltillo 88 or which core board do you love using? I would love to hear your comments and stories.

    Using AAC in daily life

    Communication is a fundamental human right, a bridge that connects us to the world and each other. For many, spoken language is the primary mode, but for individuals with complex communication needs, Augmentative and Alternative Communication (AAC) offers a powerful pathway to expression and connection. This guide will demystify AAC, highlight the crucial role of modelling, and provide practical examples of how low-tech AAC can be seamlessly integrated into everyday activities.

    What is AAC in a nutshell?

    AAC encompasses a wide range of tools and strategies that supplement or replace spoken language. It’s not about replacing speech, but rather about providing additional ways for individuals to communicate effectively. Think of it as a spectrum:

    • Unaided AAC: This involves using only your body, such as gestures, facial expressions, body language, and sign language.
    • Aided AAC: This involves external tools or devices. These can range from low-tech options like picture boards and communication books to high-tech speech-generating devices (SGDs) and apps on tablets.

    The beauty of AAC lies in its flexibility and personalisation. It empowers individuals to express their wants, needs, thoughts, and feelings, fostering independence and participation in all aspects of life.

    Modelling is KEY: Showing, not just telling

    Imagine trying to learn a new language without ever hearing it spoken. It would be incredibly difficult, right? The same principle applies to AAC. Modelling is the single most important strategy for teaching and supporting AAC users. It means actively using the AAC system yourself while talking, demonstrating how to navigate the system and express messages.

    Here’s why modelling is so vital:

    • It’s how we learn language: Typically developing children learn language by hearing it constantly around them. AAC users need the same immersion.
    • It reduces pressure: When you model, you’re not asking the individual to communicate, you’re just showing them how it’s done. This takes the pressure off and makes learning more enjoyable.
    • It expands vocabulary and concepts: By modelling a variety of words and phrases, you introduce new vocabulary and demonstrate how to combine symbols to create more complex messages.
    • It demonstrates purpose: Modelling shows that AAC is a functional and effective way to communicate, not just a set of pictures.

    So, how do you model? It’s simple: point to the symbols on the communication board or device as you speak the words. For example, if you say, ‘Time to eat breakfast,’ you might point to ‘time’, ‘eat’, and ‘breakfast’ on the board.

    Low-tech AAC in action: Everyday activities

    Low-tech AAC, such as communication boards, books, or single-page displays, is incredibly versatile and can be easily incorporated into daily routines. These can be as simple as printed pages with symbols, laminated for durability.

    Let’s explore how low-tech AAC can be used throughout a typical day, with examples of symbols:

    1. Getting ready for nursery

    Mornings can be busy, but they also offer rich communication opportunities. A ‘Getting Ready’ communication board can help sequence activities and offer choices.

    Activity example:

    ‘Time to get up!’ (point to GET UP). ‘What do you want to wear today, the blue shirt or the red shirt?’ (point to GET DRESSED) ‘Then, we brush teeth’ (point to TOOTHBRUSH) and so on.

    AAC mornings symbol examples

    2. Breakfast Time

    Mealtimes are perfect for making choices, expressing preferences, and commenting. A ‘Breakfast’ communication board can focus on food items, actions, and social comments.

    Example symbols:

    AAC meal times symbol examples

    Activity example:

    ‘What do you want to eat for breakfast?’ (point to EAT). ‘Do you want cereal or toast?’ (point to CEREAL or TOAST). If they finish their milk, you could say, ‘Are you ALL DONE or do you want MORE MILK?’ (point to symbols).

    3. Catching the Bus

    Even routine transitions like catching the bus can be communication rich. A small, portable ‘Travel’ board can be useful.

    Example symbols:

    AAC catching the bus symbol examples

    3. Being on the playground

    The playground is a dynamic environment perfect for commenting, requesting actions, and engaging in social play.

    AAC playground symbol examples

    Activity example:

    ‘Let’s PLAY!’ (point to PLAY). ‘Do you want to go on the SWING or the SLIDE?’ (point to symbols). If they are on the swing, you can say, ‘Do you want to go FAST or SLOW?’ (point to symbols) and ‘Push AGAIN!’ (point to PUSH) You can also model social language like ‘It’s MY TURN.’

    Beyond the symbols: Key takeaways

    • Consistency is key: Use AAC consistently across all environments and with all communication partners.
    • Be patient: Learning a new language takes time. Celebrate small successes.
    • Make it fun: Integrate AAC into play and enjoyable activities.
    • Follow the individual’s lead: Respond to all communication attempts, even if they are imperfect.

    In the video below I model how to integrate AAC into everyday activities with a few more examples and I discuss the difference between AAC and PECS.

    If you need some inspiration with using AAC or would like your child assessed for the right type of AAC then please get in touch.

    The joyful language toolkit: Strategies for connecting with your child through play

    As parents and therapists, we all want to help our children communicate. But sometimes, the process can feel like ‘work’. If I had a penny for every parent saying ‘I find it so boring!’… Ok hang in… what if I told you the most effective therapy happens when it doesn’t look like therapy at all?

    My approach centres on connection, enthusiasm, and multi-sensory engagement. We don’t just teach words; we teach the joy of using them. These strategies can be used whether your child is speaking, using a core board, or communicating in his or her own unique way.

    Some of my favourite strategies

    Today I want to share a few of my favourite strategies to turn everyday interactions into powerful communication opportunities regardless of why or how big a delay your child is having.

    1. Facial expressions & exaggeration: Use an exaggerated facial expression to show surprise (wide eyes!), excitement (big smile!), or confusion (a crinkled brow!). Your face is a powerful teaching tool. I am always talking like a clown in my sessions. I can announce that I have also a normal speaking voice outside my clinic room! 😊
    2. Using your voice with intonation: Your voice is music! Use a singsong or ‘tuneful’ repeat to make words stand out. For example, ‘It’s a BIIIG ball!’ or ‘Let’s GO-O-O!’. Again think: clown!!
    3. Hands and body to show: Use gestures, hands, and body movements to demonstrate. Say ‘OPEN’ while pulling your hands apart, or ‘UP’ while raising the toy high above your head.
    4. Elongating our words: Stretching out key sounds or words gives them emphasis and more time for your child to process. ‘Criiiinkley’ ‘tiiickleyyyy’
    5. Core board & language modelling:
      • Model the core board with joy: Don’t just point: point with energy!
      • Model the core board repeatedly throughout the activity, showing genuine excitement. This demonstrates the board is a joyful tool, not homework.
      • Pointing to the core board: When you say a core word, point to the corresponding symbol. You are showing your child, ‘My words live here, and your words can too’.
    6. Describing it for your child: Help your child build his or her vocabulary by providing rich sensory language. ‘It’s squishy’, ‘It’s very noisy’, or ‘It’s so smooth’.
    7. Catchy phrases: Repetitive, positive phrases create a sense of shared fun. Use them consistently: ‘Oh, that’s a nice one!’ or ‘We like that!
    8. Following your child’s Interest: Put down your agenda and follow your child’s lead. If they pick up a block, talk about the block. This ensures they are engaged and ready to learn.
    9. Allowing for pauses: This is critical! After you made a comment, allow for a significant pause (count to five in your head) for your child to fill. The silence creates a powerful opportunity for them to initiate communication.
    10. Copying your child’s sounds: If he or she makes a sound (‘buh!’), you make the sound back! Copying your child’s sounds shows him or her ‘I hear you, and your communication is important’.
    11. Lots of repetition: Hearing a word many times in meaningful contexts is how we learn! Repeat key phrases and core words throughout the activity. Repetition is the key to retention.
    12. Getting turns: Explicitly teach and celebrate getting turns in a game. ‘My turn! Your turn!’ This is a foundational social and communication skill.
    13. Using tidy up as a teaching activity: Turn cleanup into a fun game! It’s a goldmine for core words like PUT IN, ALL DONE, HELP, and MORE. For example, ‘Let’s PUT IN the red block! Yay!’
    14. Using exaggerated repeats: When your child tries a sound or word, give it back with exaggerated, tuneful repeats.

    Try out all or even just a few of these strategies, and I can promise you, you’re not just encouraging language; you’re building a joyful, reciprocal relationship based on genuine communication!

    Which strategy are you excited to try first? Let me know in the comments!

    If I can help you with any of the above, if you want to practise these a bit more, I would love to help you!

  • The tricky /R/: Mastering tongue placement for clear speech

    The /R/ sound is notoriously challenging for many children (and even some adults!). It’s one of the most complex sounds in the English language, with various pronunciations depending on its position in a word. If your child is struggling with their /R/s, you’re not alone. As Speech and Language Therapists (SLTs), we frequently work on this sound, and a key component of our therapy is focusing on proper tongue placement.

    Why is the /R/ so difficult?

    The /R/ sound requires precise coordination of the tongue, jaw, and lips. Unlike sounds like /P/ or /B/ that involve simple lip movements, the /R/ involves intricate tongue movements and tension. There are also different ways to produce the /R/ sound, which adds to the complexity:

    • Retroflex /R/: The tongue tip curls up and back towards the roof of the mouth.
    • Bunched /R/: The body of the tongue bunches up towards the roof of the mouth, while the tongue tip remains down.

    The importance of tongue placement

    Regardless of which /R/ variation is being targeted, accurate tongue placement is crucial. Even a slight deviation can result in a distorted or inaccurate sound. That’s why SLTs dedicate significant time to teaching and practising tongue positioning.

    Speech therapy techniques: Focusing on the tongue

    Here’s a glimpse into how I address /R/ sound difficulties, with a focus on tongue placement:

    • Visual aids:
      • Mirrors: I use a mirror to help children see their tongue movements and make adjustments.
      • Tongue diagrams and models: These visual tools provide a clear representation of where the tongue should be positioned.
    • Tactile cues:
      • Tongue depressors: These can be used to gently guide the tongue into the correct position.
      • Food-grade tools: Sometimes, I use flavoured tongue depressors or other tools to provide tactile feedback and increase awareness of tongue placement.
    • Auditory discrimination:
      • I help children distinguish between correct and incorrect /R/ sounds.
      • I use auditory cues and verbal feedback to reinforce proper pronunciation.
    • Exercises and drills:
      • Tongue strengthening exercises: Strengthening the tongue muscles can improve control and coordination.
      • Tongue placement drills: We practise positioning the tongue in the desired location and holding it there.
      • Sound approximation techniques: Sometimes we use other sounds to help approximate the /R/ sound. For example, I use the /L/ sound, to help achieve the correct tongue placement. Once my child has found the /L/ sound it is then a matter of pulling back just slightly to get a good /R/.
    • Contextual practice:
      • Once the child can produce the /R/ sound in isolation, we gradually introduce it into syllables, words, phrases, and sentences.
      • We also practise the /R/ sound in different contexts, such as at the beginning, middle, and end of words.

    Tips for Parents:

    • Be patient and supportive: Learning the /R/ sound takes time and practice.
    • Practise regularly: Short, frequent practice sessions are more effective than long, infrequent ones.
    • Make it fun! Use games, stories, and other engaging activities to keep your child motivated.
    • Work with an SLT: A qualified SLT can provide personalised guidance and support.

    In conclusion:

    The /R/ sound can be challenging, but with targeted speech therapy and a focus on tongue placement, most children can achieve clear and accurate pronunciation.

    Holiday disruptions & New Year routines: How to support your child’s feeding, communication and regulation over the festive season

    Holiday disruptions & New Year routines

    The festive season is a wonderful time for many families, but for children with feeding challenges, sensory differences, or autism traits, December can feel overwhelming. Changes in routine, busier environments, travel, new foods, disrupted sleep, and well-meaning relatives giving ‘advice’ can all affect a child’s feeding, communication and overall regulation.

    As a speech and language therapist specialising in Early Years, I see the same pattern each year: children often make progress during the term, only to struggle in late December when everything becomes unpredictable. The good news? With a bit of preparation, children can not only cope better, but they can actually make significant developmental gains during the holidays.

    This blog will help you feel confident, supported and prepared for the transition from ‘festive mode’ to a smoother, regulated start in January.

    1. Why routines matter so much. Especially now

    Young children thrive on predictability. For neurodivergent children or those with sensory, feeding or communication needs, routine isn’t just helpful: it’s the backbone of emotional regulation.

    In December, typical patterns change:

    • Mealtimes shift or become irregular
    • Bedtime slides
    • New foods appear
    • Loud social gatherings overwhelm
    • Travel disrupts naps and comfort routines
    • Therapies pause
    • Childcare closes

    Any one of these can lead to feeding refusals, more meltdowns, increased stimming, reduced communication attempts or regression in speech sounds.

    It’s simply the nervous system responding to too much change.

    2. Protecting feeding progress during holiday mealtimes

    My last blog and insta post have a nice social story on festive meals. They are often the trickiest part of the season for families I support. Children with sensory-based feeding challenges, or ARFID traits may find holiday foods completely unfamiliar and challenging.

    What helps:

    • Offer one ‘safe food’ at every meal
    • Keep portion sizes tiny
    • Use the ‘buffet rule’
    • Rehearse tricky moments

    3. Supporting communication when routines are disrupted

    Holiday time actually offers more opportunities for communication, just in different ways.

    Strategies:

    • Slow down and follow your child’s lead
    • Use everyday routines as language opportunities
    • Keep AAC going even if casually

    4. Understanding holiday ‘regressions’ and know they’re temporary

    This is almost always due to nervous system overload. Children don’t truly ‘lose’ skills; they temporarily prioritise regulation over learning.

    5. A gentle January reset: How to start the New Year smoothly

    • Re-establish predictability early
    • Return to preferred foods
    • Book early support if needed
    • Focus on regulation first

    Understanding phonological processes in 3–7-year-olds: What’s typical and when to seek help

    As a speech and language therapist, one of the most common questions I hear from parents is:

    ‘They can talk, but their speech still sounds immature. Is this normal?’

    Many children between the ages of three and seven use speech patterns that make their words sound different from adult speech. These patterns are known as phonological processes, and for younger children, they are a normal part of speech development.

    However, when these processes persist beyond the expected age, they can start to affect clarity, confidence and learning, especially once children enter school.

    This blog will help you understand:

    • what phonological processes are
    • which patterns are typical at different ages
    • and when it might be time to seek speech therapy support

    What are phonological processes?

    Phonological processes are patterns of sound simplification that children use while their speech system is developing.

    Instead of learning each sound one by one, children initially organise sounds into patterns that make speech easier to produce. This is a normal and efficient strategy for a developing brain.

    For example:

    • saying ‘tar’ instead of ‘car’
    • saying ‘poon’ instead of ‘spoon’
    • saying ‘bud’ instead of ‘bus’

    These are not ‘bad habits’. They are part of how speech develops.

    The key question is how long these patterns last.

    Common phonological processes (and when they usually disappear)

    Below are some of the most common processes parents notice in 3–7-year-olds.

    1. Final consonant deletion

    Leaving off the last sound in a word

    • ‘ca’ for cat, ‘da’ for dog
    • Typically resolved by 3–3½ years

    2. Fronting

    Replacing back sounds (k, g) with front sounds (t, d)

    • ‘tar’ for car, ‘do’ for go
    • Typically resolved by 3½–4 years

    3. Cluster reduction

    Omitting one sound in a consonant cluster

    • ‘poon’ for spoon, ‘top’ for stop
    • Typically resolves by 4–5 years (some clusters slightly later)

    4. Gliding

    Replacing /R/ or /L/ with /W/ or /Y/

    • ‘wabbit’ for rabbit, ‘yion’ for lion
    • Can be typical up to 5–6 years

    5. Weak syllable deletion

    Leaving out unstressed syllables

    • ‘nana’ for banana
    • Usually resolved by 4 years

    If these patterns continue past the expected age, speech can remain difficult to understand particularly for unfamiliar listeners such as teachers, peers, and also Auntie Karen or grandparents who visit once in a while.

    Why phonological processes matter in school-age children

    By the time children reach reception and Year 1, speech clarity becomes increasingly important.

    Persistent phonological difficulties can affect:

    • being understood by teachers and peers
    • phonics and early reading
    • spelling
    • confidence in speaking
    • willingness to participate in class

    Some children become aware that they ‘sound different’ and may speak less, avoid longer words, or become frustrated when misunderstood.

    What’s the difference between a delay and a disorder?

    This is an important distinction.

    • A phonological delay means a child is following the normal pattern of development, just more slowly.
    • A phonological disorder means the child is using atypical patterns, or continuing age-expected patterns well beyond when they should have resolved.

    A speech and language assessment helps identify:

    • which processes are present
    • how many are affecting speech
    • how consistent the errors are
    • and whether intervention is needed

    Signs it may be time to seek speech therapy

    You may want to seek professional advice if your child:

    • is 3½ years or older and still hard to understand
    • is understood well by family but not by others
    • becomes frustrated or avoids talking
    • has difficulty with phonics or spelling
    • uses several phonological processes at once
    • has not made progress despite time and encouragement

    Early support does not mean something is ‘wrong’. It simply helps speech development move forward more efficiently.Research consistently shows that unresolved phonological processes beyond the expected age can impact intelligibility, literacy and confidence (Dodd, 2014; Bowen, 2015).

    How speech therapy helps phonological development

    Phonological therapy is not about drilling individual sounds endlessly.

    Instead, therapy focuses on:

    • helping children recognise sound patterns
    • building awareness of contrasts (e.g. ‘tar’ vs ‘car’)
    • practising speech in meaningful, playful ways
    • supporting generalisation so progress carries into everyday speech

    For school-aged children, therapy is usually structured, motivating and highly targeted and progress can be very encouraging.

    A final reassurance

    Many children with phonological difficulties go on to develop clear, confident speech with the right support.

    If you’re unsure whether your child’s speech is ‘just a phase’ or something that needs attention, a professional assessment can give clarity and peace of mind.
