How we can help shape smooth consonant blends

ByLondon Speech and Feeding
|

For many children, especially those navigating Childhood Apraxia of Speech (CAS), the challenge isn’t just making individual sounds. It’s the ‘speech gymnastics’ required to move smoothly from one sound to the next.

You might notice that instead of saying ‘Train’, your child says ‘Ter-ain’, or for ‘Frog’, you hear ‘Fer-og’. That sneaky little ‘uh’ sound in the middle is what we call a schwa vowel. In the world of speech science, this is known as epenthesis. It’s essentially a ‘repair strategy’ the brain uses to break up a difficult cluster of sounds into two easier pieces.

While it might seem like a small detail, that tiny vowel makes a big difference in how fluent and clear a child’s speech sounds. In today’s post (and the video below), I am working with my student on ironing out that schwa by focusing on co-articulation—the art of getting the mouth ready for the second sound while still finishing the first.

The ‘best friends’ strategy

To help my student understand this complex movement, I use visual cues and a story. There are many ways to portray two sounds living closely together, but for this session, I used the ‘Best Friends’ story.

In our story, the /T/ and the /R/ are older brother best friends who want to play together. The ‘schwa’ sound is represented by a little sister who keeps trying to jump in the middle of their game! Because my student has a younger sister, this scenario was instantly familiar and helped him visualise why we needed to ‘close the gap’ between those two sounds.

Alternative methods I often use:

Beyond stories, I often use other visual and tactile methods to show the closeness of two sounds:

  • The sliding finger: I draw two dots on a paper—one for /T/ and one for /R/. We slide a finger quickly from one to the other. I might say, ‘Don’t let the ‘uh’ monster jump in the gap!’
  • The rubber band: We stretch a rubber band as we speak. I tell my student that the word is one long, smooth stretch, rather than two separate ‘pops’.
  • Visual cues for ‘quiet’ sounds: I often put my finger to my lips or tap my throat to remind a child to keep the first sound voiceless. If the voice stays ‘off’ during the /T/, it’s much harder for that schwa vowel to creep in.

The importance of ‘pure’ modelling

A major hurdle in clearing up these blends is how we, as adults, model sounds. Often, when teaching the alphabet, we say ‘Kuh’, ‘Puh’ or ‘Tuh’. But if you listen closely, you’re actually adding a vowel! If a child learns that /K/ says ‘Kuh’, it’s only natural they will say ‘Kuh-R’ for /KR/.

To give your child a cleaner blueprint, try modeling ‘pure’ sounds. Think of whispering rather than talking:

  • The /K/ sound: A short, sharp burst of air from the back of the throat. No voice! (A quiet /K/ click).
  • The /P/ sound: Just a ‘pop’ of air from the lips. If your throat vibrates, the vowel has snuck in.
  • The /T/ sound: A tiny tap of the tongue behind the teeth.

Why is this important?

You might ask, ‘If I can still understand them, does it really matter if they say “ter-ain”?’

The goal of speech therapy isn’t just functional communication; it’s building phonological awareness. When a child adds extra vowels, it can eventually impact their literacy. If they hear ‘ter-ain,’ they are much more likely to eventually spell it as ‘terain’ or ‘traint’.

By helping them master these clusters through co-articulation now, we are setting them up for success in reading and writing. And we are giving them the confidence to speak with ease.

Feel free to contact me if your child needs help with clusters or other difficulties either aligned with Childhood Apraxia of Speech or other articulation difficulties.

  • When ‘star’ sounds like ‘dar’: Understanding speech sound disorders and the path to clearer speech

    ByLondon Speech and Feeding

    If your child says ‘dar’ instead of ‘star’, you might be wondering if they will simply outgrow it or if they require specialised support. While ‘cluster reduction’—dropping one of the sounds in a blend—is a normal part of learning to talk, we typically expect these sounds to lock into place by age four years. If these errors persist as a child approaches school age, it often signals a speech sound delay that may now no longer pass without help. As a Speech and Language Therapist, I specialise in helping children bridge this gap using evidence-based techniques like backward chaining.

    This isn’t about constant correction; it’s about providing the right clinical scaffolding to move a child from ‘frustrated’ to ‘fluent’ before they hit those critical early school years.

    Dropping sounds from words is a common feature of speech sound difficulties, and while it can look small on the surface, it can have a big impact on how clearly a child is understood. In this short video clip, I’m working with a child on an /ST/ sound cluster, demonstrating how I use an evidence-based speech therapy technique called backward chaining to help children build clearer speech with confidence.

    What’s actually happening when a child drops the ‘S’?

    Clusters like /ST/, /SP/, and /SK/ are tricky. They require:

    • precise timing
    • careful airflow
    • and the ability to blend sounds smoothly

    For many children, especially those with speech sound difficulties, this is a big ask.

    So instead of hearing:

    ‘star’

    we might hear:

    ‘tar’ or ‘dar’

    This isn’t laziness or refusal. It’s the child simplifying the word to make it manageable.

    Why I don’t start by saying ‘say star’

    Telling a child to ‘just add the S’ rarely works.

    Instead, I meet them where they are already successful.

    In this clip, the child can already say ‘dar’ clearly. That’s our starting point.

    Backward chaining: building speech from success

    Backward chaining means we:

    1. Start with the part of the word the child can already say
    2. Gradually add the missing sound
    3. Keep the child feeling successful at every step

    So rather than jumping straight to ‘star’, we:

    • secure the ending
    • gently introduce the /S/
    • and blend it in a way that feels achievable

    This approach reduces frustration, builds confidence, and helps the sound stick not just in the therapy room, but out in the real world.

    Why this matters beyond one word

    This isn’t just about saying ‘star’.

    It’s about:

    • teaching the mouth a new movement pattern
    • giving the brain time to organise the sound sequence
    • and helping the child feel capable, not corrected

    When therapy feels safe and successful, children are far more likely to generalise their new sounds into everyday speech.

    Speech therapy works best when children feel supported not tested.

    If your child struggles with speech clarity

    If your child:

    • drops sounds from words
    • avoids longer or trickier words
    • or becomes frustrated when they’re not understood

    This is the kind of work I do every day building speech step by step, in a way that respects each child’s pace and strengths.

    Support can be gentle, effective, and empowering.

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

    ByLondon Speech and Feeding

    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.

    From ‘Nailed it!’ in therapy to ‘Whoops!’ at home: Why generalising speech sounds is tricky

    ByLondon Speech and Feeding

    As a parent, you’ve likely experienced the triumphant feeling when your child, who’s been working so hard on his or her /S/ sound, produces it perfectly in a therapy session. He or she is rocking those ‘sun’ and ‘socks’ words, his or her lisp seemingly a distant memory. You leave feeling elated, confident that all that hard work is finally paying off.

    Then you get home. And within minutes, you hear it: ‘Thooper!’ instead of ‘Super!’ Or maybe the clear /R/ in ‘rabbit’ from therapy reverts to a ‘wabbit’ when his or she is playing with his or her toys. It’s frustrating, confusing, and can feel like you’re back to square one.

    So, what’s going on? Why is it so difficult for children to take those amazing skills learned in a focused therapy session and seamlessly apply them to their everyday conversations? You’re not alone in wondering this. It’s a common challenge in speech therapy and understanding the ‘why’ can help both parents and children navigate this crucial stage.

    The brain’s habits: Old pathways are strong pathways

    Think of your child’s brain as having established ‘pathways’ for how he or she produces certain sounds. If he or she has been lisping his or her /S/ sound for years, that neural pathway is deeply ingrained. It’s like a well-worn path through a field: easy to follow because it’s always been there.

    In therapy, we’re essentially trying to forge a new path. We’re teaching him or her a new, more accurate way to make the sound. This new path is initially faint, like a barely visible trail. It takes conscious effort and repeated practice to strengthen it. Outside of the structured therapy environment, his or her brain often defaults to the old, comfortable, and well-established pathway, even if it’s not the most accurate.

    The demands of daily conversation: A multitasking challenge

    Therapy sessions are designed to be focused and controlled. We isolate sounds, practice them in specific words, and provide immediate feedback. There are minimal distractions, and your child’s full attention is on his or her speech production.

    Now, consider daily conversation:

    • Speed: We speak much faster in natural conversation than we do during structured practice. There is less time to think about individual sounds.
    • Cognitive load: Children are simultaneously thinking about what they want to say, understanding what others are saying, processing social cues, and managing their emotions. Adding the conscious effort of producing a new speech sound correctly on top of all that is a huge cognitive demand.
    • Variety of contexts: In therapy, we might practise ‘sun’ and ‘socks’. In real life, the /S/ sound appears in countless words, in different positions within words, and alongside a vast array of other sounds. Each new word and phonetic context present a fresh challenge.
    • Lack of immediate feedback: In therapy, the speech therapist is right there to provide instant correction and reinforcement. In a playground, during a family dinner, or while playing with friends, that immediate, consistent feedback isn’t present.

    The role of automaticity: Making it second nature

    The ultimate goal of speech therapy isn’t just correct sound production; it’s automaticity. This means producing the sound correctly without having to consciously think about it. It’s like learning to ride a bike. Initially, every pedal stroke and steering adjustment is deliberate. Eventually, it becomes second nature.

    Generalisation is the process of moving from conscious, controlled production to unconscious, automatic production. This takes time, consistent practice, and exposure to a wide variety of real-life speaking situations.

    How can we help? Bridging the gap

    So, what can parents do to help their children bridge this gap between therapy success and everyday speech?

    1. Be patient and positive: This is a marathon, not a sprint. Celebrate the small victories and avoid getting discouraged by setbacks. Your positive reinforcement is crucial.
    2. Practise little and often: Instead of long, infrequent practice sessions, aim for short, consistent bursts throughout the day. ‘Sprinkle’ in opportunities to practise their target sounds in natural conversations.
    3. Create ‘sound awareness’ moments: Gently draw your child’s attention to his or her target sounds in everyday words. For example, if he or she is working on /R/, you might say, ‘Oh, you said ‘wabbit.’ Can you try to make your /RRR/ sound for ‘rabbit’?’
    4. Model correct production: Continue to model the correct production of their target sounds in your own speech.
    5. Collaborate with your speech therapist: Your therapist is your best resource! Ask them for specific strategies and activities you can do at home to support generalisation. They can also provide guidance on when and how to gently correct your child.

    Tips and tricks

    Below I have listed a few good tips and tricks that can help the transition from therapy room to daily life:

    Empowering your child as the ‘sound detective’:

    • ‘Secret sound listener’: Instead of you doing the correcting, make your child the detective. When you’re having a conversation, say ‘your /S/ sounds are sometimes a bit “slippery”’ (or whatever fun, non-judgmental term you like). Ask your child to quietly listen for your /S/ sounds. You can even purposely make a few ‘slippery’ ones (or correct yourself immediately after) and see if they notice. This shifts the focus from being corrected to actively listening and identifying the sound in a non-threatening way.
    • ‘Sound scorecard’: For a short period (maybe 10–15 minutes during a specific activity, like dinner or a game), provide a small notepad and pencil. Explain that your child is going to listen for his or her /S/ sounds and gently mark a tally every time he or she uses it correctly. The goal isn’t perfection, but awareness. This gives your child agency and a visual representation of progress. You can even make it a game: ‘Let’s see how many /S/ sounds we can catch in five minutes!’
    • /S/ sound song/rhyme creation: Work together to create silly songs or rhymes that are packed with /S/ sounds. The sillier, the better! You can sing them in the car, while doing chores, etc.
    • /S/ sound superpower: Frame the new sound skill as a ‘superpower’. ‘You’re getting so good at using your /S/ superpower! It’s going to help you speak so clearly and confidently.’
    • Highlighting successes: Always go out of your way to acknowledge and praise successful /S/ productions in natural conversation. ‘I really understood you clearly when you said ”s_top”.’ or ‘That /S/ sound was perfect when you told me about the “s_tory”!’

    Important considerations:

    • Keep it low-pressure: The goal is generalisation, not perfection. If your child is feeling pressured, he or she will likely revert to old patterns.
    • Focus on awareness, not just correction: Help your child become aware of his or her own speech rather than relying on you for corrections.
    • Short, frequent bursts: A few minutes of subtle focus multiple times a day is more effective than one long, forced session.
    • Acknowledge feelings: If your child expresses frustration about ‘being corrected’, validate these feelings. ‘I understand it can feel like a lot of listening, but we’re just trying to help you use that super /S/ sound all the time!’

    By incorporating these strategies, you can help your child naturally integrate the new /S/ sound into daily speech, fostering independence and confidence without it feeling like constant ‘testing’ or ‘correction’. Generalising new speech sounds is arguably the hardest part of speech therapy, but it’s also the most rewarding. With patience, consistent effort, and a collaborative approach between parents and therapists, children can successfully integrate their new, clearer speech sounds into every aspect of their daily lives.

    Empowering non-speaking children: the power of AAC Core Boards

    ByLondon Speech and Feeding

    Communication is the essence of human interaction, allowing us to express thoughts, feelings, wants and needs. For non-speaking children and their families finding an avenue to communicate effectively can be a really challenging journey.

    Augmentative and Alternative Communication (AAC) offers a solution: with AAC Core Boards as a powerful ally and tool to empower and express more than requests: ideas, comments, surprise and delight, as well as saying no to something! Very important!

    “AAC is a set of tools and strategies that an individual uses to solve every day communicative challenges. Communication can take many forms such as: speech, a shared glance, text, gestures, facial expressions, touch, sign language, symbols, pictures, and speech-generating devices” (RCSLT, 2023) to name just some.

    AAC Core Boards are a powerful tool to empower non-speakers to express ideas. In this blog, we’ll explore the significance of AAC Core Boards and how they can unlock the world of communication for non-speaking children.

    Let’s discover and understand AAC Core Boards

    Firstly, let’s look at what a Core Board looks like…

    AAC Coreboards
    Credit: Saltillo Word Power

    Why not have a go and download your own copy (and other boards) for free on the Saltillo Word Power website.

    AAC Core Boards are a specific type of AAC system that employs a grid-style board. This grid contains a set of core vocabulary words or symbols, which serve as a foundation for all communicative functions (e.g., initiating, greeting, requesting, negating, commenting, asking a question, and expressing surprise).

    These boards incorporate high-frequency (most used) and versatile words. They enable us to construct sentences, express emotions, and take part in conversations, fostering a sense of independence and autonomy. By enabling communication, we also remove some of the frustration (from not being able to communicate) which contributes/or often leads to behavioural difficulties.

    Building literacy skills

    AAC Core Boards are not only tools for immediate communication. They also play a pivotal role in language and literacy development. By using these boards, non-verbal children engage with words and symbols. It reinforces their understanding of language structure and grammar.

    As they consistently play with and then use their boards, they naturally absorb language patterns, laying the foundation for improved literacy skills. This immersive learning experience paves the way for future language acquisition and communication growth.

    Customisation for individual needs

    Every child is unique, and their communication needs can vary significantly. AAC Core Boards are designed with this diversity in mind, allowing for customisation to suit individual preferences and abilities. The boards can be adapted to include specific vocabulary relevant to a child’s daily life, interests, and activities. This personalisation ensures that the AAC Core Board is a true reflection of your child’s personality and needs, making communication more motivating, engaging and effective.

    Collaboration between AAC Core Boards and Speech Therapy

    AAC Core Boards are an excellent tool but we need to know one important aspect: they only work well when used regularly by the child’s family and key people in the first place.

    The board needs to be used and modelled by adults consistently and regularly across environments. This is so our children know what to expect, take an interest and begin to use the boards themselves. Modelling the use of AAC Core boards is vital. Think how long it typically takes for a child to learn their first word. Around a year! During that time the adults talk constantly to their child without hesitation or expectation! The same goes for introducing this new way of communicating.

    Collaborating with your child’s Speech and Language Therapist (SLT) ensures that your child receives the right guidance in using the AAC system. SLTs can assess your child’s communication abilities, recommend appropriate boards and provide guidance on how to best put them in place, so that your child can reach their communicative potential.

    For non-speaking children, AAC Core Boards are more than just tools. They are bridges to a world of communication, connection, and empowerment. These boards harness the power of visual communication, foster language development, social interaction, and personal expression. They can be tailored to individual needs with the support of skilled professionals. AAC Core Boards offer a beacon of hope, helping to break through communication barriers and thrive in a world that is waiting to hear your child’s voice.

  • Explore 12 questions to determine whether your child may be Autistic

    ByLondon Speech and Feeding
    A young boy is in the foreground and has turned his head away from the woman sitting next to him.
    May your child be autistic?

    As professionals, when diagnosing young children with an Autistic Spectrum Condition, it is vital we work as a multi-disciplinary team, so you will likely see many professionals. This may include Educational Psychologist, Dietician, General Practitioner, Occupational Therapist, Paediatrician, Special Educational Needs Coordinator, Speech and Language Therapist and Social worker. Once the evidence is collated, then a diagnosis may be made.

    You may be wondering what are some of the early signs of social communication difficulties? Whilst no autistic child is the same and we know Autism is very much a very wide spectrum of abilities and needs there are some autistic spectrum characteristics we do typically see in the early years of childhood. You may wish to think about these areas or presentations to help you prepare for the Speech and Language Therapy appointment.

    Twelve questions

    1. Does your child respond to their name?
    2. Are they fixated with watching their hands?
    3. Do they have sensory processing difficulties such as bright lights, food textures, or loud noises?
    4. Are they meeting their milestones or are they delayed?
    5. Do they flap their arms or legs when excited?
    6. Have you noticed any rocking back and forth?
    7. Do they blink excessively or display any facial tics?
    8. Do they play with a particular sort of toy e.g. spinning toys?
    9. Have you noticed that they lack interest in toys?
    10. Have they regressed in their language? Perhaps you’ve noticed they are not using words that they have previously learnt.
    11. Do they use gestures to communicate their needs? How do they communicate their wants and needs?
    12. Do they appear to be in their own world?

    You are not alone

    These questions are by no means exhaustive and there are many more factors to consider. But it is important to trust your instincts as you are the expert on your child and know your child the best. Regardless of whether you see all of the above points or none, do not hesitate to have an assessment if you are concerned as, even if it turns out to be nothing to worry about, there is always at least one or two great pieces of advice I can offer you on the way and you will leave feeling hopeful and empowered. It’s always best to seek early intervention with communication difficulties. This allows strategies and support to be put in place. Never feel alone, always speak out.

    Conquering the ‘slushy’ /S/: Your guide to treating lateral lisps

    ByLondon Speech and Feeding
    Conquering the ‘slushy’ /S/: Your guide to treating lateral lisps

    As a speech therapist, few things are as rewarding as helping a child find their clear, confident voice. Among the various speech sound disorders, the ‘lateral lisp’ – often described as a ‘slushy’ or ‘wet’ /S/ sound – presents a unique challenge. While it can be tricky to treat, I’m thrilled to share that I’ve had significant success in helping children overcome this particular hurdle.

    What is a lateral lisp?

    Most people are familiar with a frontal lisp, where the tongue protrudes between the front teeth, resulting in a /TH/ sound for an /S/ (e.g., ‘thun’ for ‘sun’). A lateral lisp, however, is different. Instead of the air escaping over the front of the tongue, it escapes over the sides, often giving the /S/ and /Z/ sounds a distinct, muffled, or ‘slushy’ quality. This happens because the tongue is not forming the correct central groove, allowing air to spill out laterally.

    The science behind a perfect /S/ vs. a slushy one

    To understand how to fix a lateral lisp, it’s helpful to understand how a ‘perfect’ /S/ sound is made. Imagine a narrow, focused stream of air. For a clear /S/ sound, your tongue forms a shallow groove down its centre, directing a precise, thin stream of air right down the middle, over the tip of your tongue, and out through a tiny opening between your tongue and the roof of your mouth, just behind your front teeth. This focused airflow creates that crisp, sharp /SSSS/ sound we recognise.

    Now, picture what happens with a lateral lisp. Instead of that neat, central channel, the tongue is often flatter or positioned in a way that allows the air to escape over one or both sides. Think of it like a river overflowing its banks – the air, instead of flowing in a controlled stream, spills out sideways, creating that characteristic ‘slushy’ sound. This lateral airflow is what we need to retrain.

    Why is it tricky to treat?

    Treating a lateral lisp can be challenging for a few reasons:

    • Habitual muscle memory: The way the tongue moves and positions itself for a lateral lisp is deeply ingrained. It’s a motor habit that needs to be unlearned and replaced with a new, more precise movement.
    • Subtle differences: The difference between a lateral lisp and a correct /S/ sound can be quite subtle to perceive, both for the child and sometimes even for parents. This makes it harder for the child to self-monitor and correct.
    • Oral motor control: It requires fine motor control of the tongue muscles to create and maintain that central groove for airflow.

    My success with children aged six years and over

    I’ve found great success in treating lateral lisps, particularly with children aged six years and older. Why this age group? By this age, children typically have:

    • Increased awareness: They are more aware of their speech and often more motivated to make changes. They can better perceive the difference between their ‘slushy’ /S/ and a clear one.
    • Improved cognitive skills: They can understand and follow more complex instructions and strategies.
    • Better self-monitoring: Their ability to listen to themselves and correct their own speech improves significantly.
    • Enhanced oral motor control: Their fine motor skills, including those of the tongue, are more developed, allowing for greater precision.

    My approach focuses on a combination of auditory discrimination, tactile cues, and targeted myofunctional exercises to help children ‘feel’ the correct airflow and tongue placement. We use a variety of engaging activities to make the process fun and effective.

    It is crucial to understand tongue functioning and focusing on correcting improper oral resting posture and muscle function, which are often significant contributors to a lateral lisp. For example, if the tongue rests low and wide in the mouth consistently, or if there’s a tongue thrust during swallowing, these habits can prevent the tongue from achieving the precise, midline placement necessary for a clear /S/ or /Z/ sound. Through targeted exercises I aim to re-educate the oral and facial muscles, promoting correct tongue posture at rest, during swallowing, and, ultimately, during speech production. By strengthening the muscles responsible for tongue lifting and encouraging a more appropriate swallowing pattern we can establish the correct oral motor skills needed to overcome a lateral lisp and achieve clearer articulation.

    The recipe for success: Little and often

    The single most crucial ingredient for success in treating a lateral lisp is daily home practice of all the strategies given. This isn’t about long, arduous sessions; it’s about consistency. Think of it like building a muscle: short, frequent workouts yield better results than sporadic, intense ones.

    My recommended formula is ‘little and often’. This means:

    • Short, focused sessions: Aim for 5-10 minutes of practice, 2-3 times a day. This prevents fatigue and keeps the child engaged.
    • Integrate into daily routines: Practise while waiting for dinner, during a car ride, or before bedtime. Make it a natural part of their day.
    • Positive reinforcement: Celebrate every small success! Encouragement goes a long way in building confidence and motivation.
    • Parental involvement: Parents play a vital role in providing consistent cues and encouragement at home. I equip families with clear, easy-to-follow strategies.

    Overcoming a lateral lisp requires dedication, but with the right guidance and consistent practice, a clear, confident /S/ sound is achievable. If your child is struggling with a ‘slushy’ /S/, please don’t hesitate to reach out. Together, we can achieve success!
