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

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.

    Why ‘Prosody’ Matters in Childhood Apraxia of Speech (CAS)

    Prosody refers to the ‘music’ of speech — the rhythm, pitch, stress, and volume that convey meaning and emotion beyond the literal words themselves. Think about a monotone statement like ‘Really?’ compared to one with a rising inflection, expressing genuine curiosity.

    When I work with children on producing speech sound sequences, we focus on mastering individual sounds and then putting them together into target words. A crucial element that can significantly impact a child’s speech production is ‘prosody’.

    In CAS, where the difficulty lies in planning and executing the motor movements for speech, prosody can be a powerful tool for producing clearer words and phrases.

    Here’s why working on prosody is an essential tool in CAS speech therapy:

    1.  It aids Motor Learning:

    Apraxia of Speech means that the planning and execution of speech movements are impaired. When we use exaggerated intonation or stress patterns while modelling words, we are providing additional prosodic variation and, therefore, additional auditory cues. These cues often help my student to carry out the correct motor movements for a word or syllable sequence.

    For instance, I might say ‘ball’ with a high-pitched emphasis on the ‘b’ sound. This auditory cue might be more effective in guiding the child’s tongue placement than simply repeating the word without variation.

    In this little video clip I get my student to say the word ‘snuggle’ (since we were working on that particular sound sequence: snuggle, snout, snore and sneeze) with a high voice and then a lower voice ‘like a bear’ — again it provides that extra auditory cue, but, in addition, the fun aspect also helps to take away the intense focus on a tricky movement pattern.

    By now the new pathways have been laid through repeated practice and now automaticity takes over and without too much effort my student can suddenly produce a motor pattern. It’s magical when it happens and gives me such a thrill.

    2. It makes speech more engaging and natural sounding:

    Children with CAS often sound robotic or flat due to challenges with prosodic elements. By incorporating variations in pitch, volume, and rhythm during therapy, we can help achieve a more natural flow of speech

    3. It makes it easier to express our emotions:

    Children with CAS often struggle to express themselves emotionally; partly through the difficulty of producing clear words — period, but also in addition due to the difficulties or absence of musicality and rhythm in their speech.

    Therefore, it is so important to incorporate activities focused on practising different emotions with varied intonation patterns. This can really empower our students to put emotions into their words.

    Good words to practise are fun words like ‘Wow!’ or ‘Yeiih’ or power words and phrases like ‘No!’ or ‘Gimme that’ etc.

    Making Therapy Fun and Engaging:

    Speech therapy for CAS doesn’t have to be all drills and exercises (though to be fair sometimes we can’t quite get round to making each and every word huge fun though we try…).

    I aim to make all my sessions fun and have intrinsic rewards built into the speech practice where possible.

    Home practice tips:

    Therapy shouldn’t exist in a bubble. Working on prosody during sessions is crucial, but it’s equally important to integrate these skills into everyday interactions. Parents and caregivers can model appropriate prosody during playtime, story time, or even simple conversations. This consistent reinforcement helps our children to generalise their newfound skills and use them naturally in their daily lives.

    • Sing songs and rhymes: Songs naturally incorporate variations in pitch and rhythm. Singing familiar songs and creating silly rhymes can be a delightful way to practise prosody.
    • Use puppets and toys: Assign different voices and personalities to puppets or toys. This encourages children to experiment with pitch and volume to differentiate characters.
    • Read aloud with enthusiasm: Model expressive reading, varying your voice for different characters and emphasising key words. This makes reading time engaging and helps children understand the power of prosody.

    Please feel free to contact me if your child has speech sound difficulties. It is my passion. I love supporting children with apraxia.

    Strategies to support children with eating difficulties

    where the cause is NOT a swallowing problem, but we are having a “fussy eater” in the family, seeming for no obvious reason

    When parents have a child who find mealtimes or eating difficult, it can put pressure on the whole family dynamics. Once we have observed a child’s eating and drinking skills and found that they are not swallowing impaired, but are for want of a better word “fussy” or “picky”, we can then start to look at what might be underpinning the food aversions/picky eating/food avoidance. Two of the main questions parents have (of course) are:

    • ‘is my child getting the right nutrition?’
    • ‘how can I have less anxiety-provoking and stressful mealtimes?’

    We all tend to have an image in our minds about the ‘perfect mealtime’, and how mealtimes ‘should’ be. Speech and Language Therapists with a Feeding Specialism are the perfect professionals to help you unpick feeding issues. We are trained to look at swallowing and oral skills and we also know a lot about feeding behaviours and sensory difficulties which could be causing your child’s eating avoidance.

    Here are some strategies that can support children with their eating:

    1. Create and maintain a mealtime culture that suits your home and lifestyle. Then stick to that. We all need some routine in our lives to thrive. Mealtimes are no different. It might be that you eat in the same place for every meal, with the same knives and forks, concentrating on maintaining good posture. Children learn by repetition so the more familiar it is, the easier they will find it. In the physical sense, our bodies also need preparing for food, regardless of whether we are eating with our mouths or we are tube-fed. We want every child to connect all the dots of the process. It starts with their eyes, noses, expectations, memories of past experiences, feelings and then finally their mouths….
    2. Be an excellent role model. Children learn through watching others, so your child will be observing you without you knowing. Ensure that you are positive about the food you are all eating, and talk about how delicious, tasty, juicy, and yummy the foods are. Make the atmosphere around the dinner table light hearted. Even though you are secretly stressed about your child not eating, try and not show this. Instead pick a topic or put on some nice music, or talk about something your child might be interested in, and try and avoid coercing your child to eat. Leave small finger foods on their plates and have a range of foods available on the table so that your child can see that everyone is eating a range of foods and enjoying them.
    3. Use positive reinforcement. Try and think of mealtimes as fun and motivating. Children who are happy will likely be more inclined to try foods and take part in family mealtimes. Reward all interactions around food, so if your child merely touches a new food then praise this behaviour. Or if your child licks a food just once, again make a nice comment and praise your child for touching and licking the food. The takeaway here is to try and keep all messages positive around food.
    4. Keep offering all types of food. What often happens is that parents stop serving foods they know will not be eaten. This makes sense in a way; we don’t want wastage! However, try and keep the doors open and re-offer all types of foods, even the ones that your child has not wanted in the past. Try and give your child one food they will like and one food they have tasted before and liked before, even a little, and then one new food to try. So, your child always has something to fall back on and they can join in with eating. But they can also try (or at least look at and think about trying) other foods that you and perhaps the siblings are eating.

    Take a look at this website, I find it very helpful in showing parents what types of foods and how big a portion to offer

    Have a go and try and implement some of the ideas above, and should you get stuck please get in touch!

    The purpose and nature of a speech and language therapy assessment

    If you have ever wondered what happens when you bring your child to a speech and language therapy assessment, then this blog will shed light on the ins and outs of it for you.

    At its heart, a speech and language therapy assessment is a systematic and thorough evaluation of your child’s communication or eating/swallowing abilities. It’s more than just asking a few questions. It is a carefully constructed process designed to identify strengths, pinpoint challenges, and ultimately pave the way for effective intervention.

    Establishing a detailed profile – a few bullet points:

    • Identification of communication and swallowing difficulties: I aim to determine if a communication or swallowing disorder exists. I will establish if the difficulty is a delay or a more complex disorder.
    • Diagnosis of the specific disorder/autism: The assessment delves deeper to pinpoint the specific type and nature of the difficulty. For instance, is your child’s language delay due to a specific learning disability, a developmental delay, or another underlying condition?
    • Knowing the aetiology or what is causing a difficulty is crucial for targeted intervention. And whilst we are on the topic let’s talk about an autism assessment: I am trained and experienced in assessing and diagnosing autism. However, when it comes to the diagnosis of autism I provide a preliminary ‘working hypothesis’ rather than giving a definite final diagnosis. The reason for this is that it is considered the ‘gold standard’ and ‘best practice’ to diagnose autism in a multi-disciplinary setting and context. Since I work on my own, I always refer to highly recommended multi-disciplinary clinics for the ultimate diagnostic assessment.
    • Determination of severity: Understanding the severity of the difficulty is essential for prioritising intervention and measuring progress. Is your child’s difficulty mild, moderate, or severe? This helps me choose a particular approach and then tailor it to suit each individual child.
    • Identification of underlying strengths and weaknesses: An assessment doesn’t just focus on what’s wrong. It also highlights your child’s strengths and areas of relative ease. This information is invaluable for building upon existing skills during therapy. Understanding weaknesses provides specific targets for intervention.
    • Guiding intervention planning: The assessment provides the crucial information I need to develop an individualised intervention plan. The findings directly inform the selection of therapy goals, strategies, and techniques. Without a thorough assessment, therapy would be a shot in the dark.

    A multi-faceted approach

    A speech and language therapy assessment is not a ‘one-size-fits-all’ procedure. The specific tools and techniques used will vary depending on a child’s age, the nature of the suspected difficulty, and other relevant factors. However, most comprehensive assessments incorporate several key components:

    • Case history: This involves gathering information about your child’s developmental, medical, social, and educational background. We will go through all the relevant milestones and throughout the process I will make notes which will help bring all the puzzle pieces together.
    • Observation: I will observe how parent and child play together and we also look at how the child plays by themselves. Additionally of interest is how a child plays with me, the therapist. Through discussion I will also endeavour to find out how your child plays with other children, be it at the nursery or within the family.
    • Standardised assessments: These are commercially available tests with specific administration and scoring procedures. They provide norm-referenced data, allowing to compare the individual child’s performance to that of his or her peers. Examples include articulation tests, language comprehension and production tests, and fluency assessments. I tend not to use these assessments a lot.
    • Instead, I use non-standardised assessments: These are more flexible and allow to probe specific areas of concern in more detail. This might include language samples (analysing spontaneous speech), dynamic assessment (testing and teaching to identify learning potential), and informal observation of play or interaction.
    • Immediate feedback and report writing: During and thenfollowing the assessment, I will bring all the gathered information together and I will discuss with the parents what my findings are and what my recommendations in the short term are. Parents always go home with a good handful of useful strategies that they can implement at home right away. In addition, I provide a comprehensive report outlining the findings, diagnosis (if applicable), severity, strengths and weaknesses, and recommendations for intervention.

    In conclusion, a speech and language therapy assessment is a dynamic and essential process. It is a journey of discovery, aiming to understand a child and the child’s family and his or her unique communication or feeding profile. The assessment is usually the start of our wonderful learning journey together.

    Below is a short video clip of an assessment where you see me in action explaining a particular therapy approach to a set of parents. It perhaps shows a tiny bit of how relaxed we are in our sessions and that assessment is not at all daunting, but a hugely informative event overall which will leave you feeling empowered and hopeful.

    What happens after an assessment?

    Please feel free to get in touch with me via my contact form if you wish to have an assessment for your child’s communication difficulties or feeding difficulties.

    An assessment is always a stand-alone event and does not mean you need to automatically book follow up sessions at all. It will give a lot of information and based on this you can decide if you would like more therapy or follow up for you and your child. Many times ongoing therapy is not needed! I only recommend a course of therapy if it is really needed and where it would be immediately beneficial for your child.

    The joy of container play: Exploring play development and understanding of how things work

    Have you heard the term ‘Container play’? I use this very often with children in my sessions as it is so versatile and an enjoyable activity that can be done in parallel with a child or together. Container play is a powerful tool for fostering development in young children, especially those with developmental delays. This seemingly mundane activity provides a rich environment for sensory exploration, motor skill development, and cognitive growth.

    What is container play?

    Container play involves children interacting with various containers—boxes, buckets, bowls, cups, various bags, etc.—and filling, emptying, and transferring objects within and between them. Objects can include literally anything: small beads, bead chains, table tennis balls, wooden pegs, dinosaurs or any other little person toy, blocks of varying sizes, sand, water, or any other safe material. Larger containers obviously take larger items: socks, stuffed animals, bigger balls, bigger blocks etc really the choices are endless.

    Benefits for children with developmental delays:

    Sensory exploration:

    • Touch: Children explore different textures and temperatures of containers and objects.
    • Sight: They observe how objects look inside and outside the containers, how light reflects off them, and how colours change.
    • Sound: They listen to the sounds of objects clinking, rattling, and splashing.
    • Proprioception: Filling and emptying containers helps develop body awareness and spatial awareness.

    For neurodivergent children who might have sensory regulation difficulties, consider the following adaptions to accommodate your child’s sensory needs:

    • Over-stimulation: For children who are easily overstimulated, start with simple setups using a limited number of containers and objects. Gradually increase the complexity as they tolerate it.
    • Under-stimulation: For children who seek sensory input, provide a variety of textures and materials, such as sand, water, slime, or beans.
    • Temperature: Offer a variety of temperature options. Some children may enjoy warm water or cool sand.
    • Lighting: Adjust the lighting to create a calming or stimulating environment.
    • Focus on one sense at a time: Initially, focus on one sensory aspect, such as the feel of sand or the sound of water.
    • Weighted containers: Use heavy containers filled with rice or beans to provide deep pressure input.
    • Fidget toys: Incorporate fidget toys into the activity to provide sensory input and help with self-regulation.
    • Tactile exploration: Encourage exploration of different textures using objects with varying surfaces.

    Fine motor skill development:

    • Hand-eye coordination: Scooping, pouring, and transferring objects require precise hand-eye coordination.
    • Pincer grasp: Picking up small objects helps develop fine motor skills like the pincer grasp.
    • Strength and dexterity: Manipulating containers and objects strengthens hand muscles and improves dexterity. Opening and closing containers can be a huge area of interest; how does the top screw back on, or off?

    Cognitive development:

    • Cause and effect: Children learn that their actions (e.g., pouring water or sand) have consequences (e.g., the water spills).
    • Spatial awareness: They develop an understanding of concepts like inside, outside, full, empty, and over/under; also how big is the vessel and how much goes in before it’s full or spills over. How small is the vessel opening and what do I need to do to get the beads into the container.
    • Problem-solving: Children learn to solve problems, such as how to get an object out of a narrow container or how to transfer water without spilling.

    Social and emotional development:

    • Communication: Container play can encourage communication as children interact with others, sharing toys and commenting on their actions. Asking for help to open and close a container is often a great opportunity to practise ‘help me’ or ‘open it’
    • Turn-taking: Sharing containers and materials helps children learn to take turns and cooperate.
    • Sensory regulation: For children with sensory sensitivities, container play can be a calming and self-regulating activity.

    Tips for engaging children in container play:

    • Create a safe and inviting environment. A shower curtain on the floor makes things easier for tidy up afterwards. And it allows for spillages.
    • Provide a variety of containers: Use different sizes, shapes, and materials. Use containers that are visually interesting and pleasing, perhaps a festive biscuit tin, or a tin that looks like train engine. Use see-through containers at first which make the filling and emptying more obvious. This is important for children who have no previous experience with this type of play and need to ‘warm up’ to it. Once a child loves and is used to container play you can go wild with all types of containers.
    • Offer a variety of objects: Include balls, blocks, sand, water, and other age-appropriate materials.
    • Join in the fun! Start off the process, show your child what the joy of the activity is for yourself, how fun it is to fill and empty containers, provide enough containers for your child to start playing alongside you, and comment on their actions.
    • Follow your child’s lead: Allow them to explore and experiment at their own pace.
    • Adapt activities: Adjust the level of challenge based on your child’s abilities and interests.

    Container play is a simple yet powerful tool that can support the overall development of young children, especially those with developmental delays. By providing a rich and engaging sensory experience, container play can help children build essential skills in motor, cognitive, social, and emotional domains.

    If you have any questions or would like to have more in-depths demonstration of this or other play styles for your child please contact me.

    I look forward to hearing from you.

    How to model AAC with our minimally speaking students?

    modelling AAC

    How should we start? Should we use prompts? What kind of prompts? hand-over-hand or just pointing? Should we wait, and, if so, how long? Introducing an alternative communication system (AAC) to our child is for many of us a confusing and sometimes scary prospect, but it needn’t be! Let me reassure you and share some tricks of my practice in this area.

    Once we have decided to try for a picture based communication system, I usually start with a paper-based single page with between 48–88 core-words. I choose the number of words depending on where the child is developmentally and also verbally.

    If a child does have a small handful of words already, I might start with the 88-cell board below. If, on the other hand, my student is completely non-speaking and still quite little then I might go for the 48-cell below here or I might have even less cells to start with. Again, sometimes I start with an electronic device in my clinic just to trial and introduce the idea and to see if, or how, a student responds. 

    Below are some samples: a 49-cell board which I made for a child in a nursery setting

    Below a Saltillo WordPower board that can be downloaded from the Saltillo website:

    Example of a slightly more advanced board, again from the Saltillo Website

    And here below one example of a board I made for a specific activity for a child who loves water and sand play:

    It is perfectly possible to be very flexible and create a suitable board for any student, starting with as few as 2–5 cells and working up to over a 100 (very small ones) on a sheet of A4 or A3 paper.

    So once we have a good board for our child, what now? How do we start introducing this into our daily life?

    We can start by showing/pointing to the word GO within a play activity. For example:

    • a car run,
    • or a marble run,
    • or a spinner activity,
    • a wind-up toy,
    • anything that can be stopped and started easily.

    How to start?

    I will talk us through each of the steps using the example for the word ‘GO’.

    First phase

    The first phase is a TEACHING/ LEARNING PHASE. In this phase we do not expect our student to do anything, to copy us or to point to the board. If they do that it is of course a huge bonus and we will celebrate it.

    Our job is to simply MODEL/SHOW/GIVE EXAMPLES of how we can use the board, by steadily and regularly pointing to the chosen word or words. We do so across the day and across settings:

    • play
    • meal time
    • getting dressed/undressed
    • bath time
    • going to the car/shops
    • etc

    Once we can be sure that our student has been submerged and SOAKED in seeing the coreboard being used, say after some 3–4 weeks of using it consistently…

    Second phase

    We can begin to move into the second phase which is the PRACTICE PHASE. By now the student has seen the boards and he or she has seen the word GO (as a example) modelled many times.

    Now we can start to see if we can tempt our student into trying this out for themselves.

    What sort of TEMPTING are we talking about? Take a look at the Prompt Hierarchy below, which shows us what to do to get our student to be independently communicating as soon as possible. 

    The PROMPT HIERARCHY: what sort of prompting should we do, should we expect something from our student or how should we view this stage?

    1.  TEMPT AND PAUSE

    I have the AAC near to the toy and each time the child starts another round of the activity I say clearly ‘GO’ and I point to the picture as do so. I then pause and wait to see what happens. NOTHING? Then…

    1. USE SIGNS AND BODY LANGUAGE

    Next time the child starts another round I might be very animated and do a Makaton sign for GO as I say ‘GO’ and I make a very over point to the picture again. Then I wait. STILL NOTHING? OK then…

    1. OPEN-ENDED QUESTION

    Now I might say ‘GO’ and follow with: ‘OOH I WONDER IF THERE IS A PICTURE TO POINT TO…’

    ‘OH LOOK HERE IS GO!’ I then point to GO.

     STILL NO RESPONSE?

    1. ASK FOR A RESPONSE

    I might say ‘GO’ followed by ‘LOOK! LET’S POINT TO GO HERE ON THE PICTURE.’

    STILL NO RESPONSE? 

    1.  PHYSICAL TOUCH

    Next time I say ‘GO’ I will try and take the student’s hand, help isolate their finger and help him or her to point to the actual picture.

    REMEMBER: Prompting serves a very important function in scaffolding learning for students BUT if we are constantly prompting kids, then we are teaching them to only communicate when someone tells them to. We want our student to become as independent in speaking and using words as possible.

    So once I have done Physical Prompting I will try and phase back down to number 1 where all I need to do is point to the picture or look at the board with the aim that the student will then point to the picture.

    Take away points:

    • Keep the learning phase pressure-free and model without expecting our student to jump in. In other words, let’s model first without expectation. Later we can have a little bit of expectation.
    • After they’ve been exposed to and have been ‘soaked’ in plenty of AAC input, then, YES, we can create an opportunity to help them say or point to the word on their own.
    • We can model BOTH with and without expectation.
    • Only after LOTS of exposure, use the least to most prompting hierarchy and start creating opportunities for a student to become an independent communicator.

    Do get in touch if you have any questions or comments or if you would like some practical help.

    I am always pleased to hear from you.

    Speech Sound Challenges: A focus on /L/ and /Y/

    Have you ever thought about how difficult it can be to produce certain speech sounds? Some sounds are definitely trickier than others. This is especially true for children with speech sound disorders like Childhood Apraxia of Speech (CAS).

    My student with CAS has been working hard on producing the /L/ sound especially when it was followed by an /O/ or /OO/ like, ‘log’ or ‘look’. We’ve practised lots and now that he’s got a good handle on /L/, he’s started replacing another difficult sound, /Y/, with it. So, ‘yes’ becomes ‘less’ and ‘yuck’ becomes ‘luck.’

    This is a common pattern in speech development. Once a child masters a new sound, they may start using it in place of other sounds they find even more challenging.

    Minimal Pair therapy

    I use different evidence-based methods to help my students. And I often like to start out with phonemic awareness and then I move to contrasting the error sound with another sound to make completely different words. This approach is called ‘minimal pair’ therapy: both words are the same except for the initial/final sound which has the error sound, and this is contrasted with the correct sound.

    Below is an example of this:

    After we have worked on sound awareness, listening and becoming aware of small units of sound matter, then we can move to working on tongue placement and movement.

    Tongue placement and movement to produce correct /L/ and /Y/ sounds

    To produce these sounds correctly, the tongue needs to be in specific positions and make specific movements.

    • /L/ sound:
      • Tip of the tongue touches the alveolar ridge (the bony ridge behind your upper teeth)
      • Sides of the tongue are raised to the sides of the upper teeth
      • Airflow escapes through the sides of the tongue
    • /Y/ sound:
      • Tip of the tongue touches the roof of the mouth behind the alveolar ridge
      • Sides of the tongue are raised to the sides of the upper teeth
      • Airflow escapes through the centre of the mouth

    I also use:

    • Auditory bombardment: Auditory bombardment is a technique that involves repeatedly listening to a target sound. This can help children to develop a better understanding of the sound and how to produce it.
    • Visual cues: Visual cues can be helpful for children who are having difficulty producing a particular sound. Here I use the image of a ‘standing tongue’ versus a ‘sitting tongue’.
    • Physical cues: I use my hands to show a ‘standing tongue’ for the /L/ versus a ‘sitting tongue’ for the /Y/. But what worked even better and sadly I don’t have the video clip for it:
    • Semantic cues: For example a picture of an ‘EAR’ to make the sound /Y/ so we shape the sound /EA/ to /Y/.
    • Parent involvement: Parents play an important role in their child’s speech sound development by providing opportunities for them to practise their speech sounds at home. This can be done through activities such as reading books, singing songs, and playing games.
    • Reinforcement: It is important to praise children for their efforts, even if they are not perfect. This will help them to feel motivated to keep practising. Important here for speech correction is concrete reinforcement: I feed back to my student what exactly they were doing correctly with their tongue or lips. Rather than saying ‘well done’, I mention what my student has just done with the tongue to change the sound: ‘I saw you lowered your tongue! That made a good /Y/’.

    Another great way of reinforcing positively is to ask the student how they feel they have done? For the older ones I often ask them to self-rate their sound production out of 10. Then we can work towards the next incremental number upwards. This is very effective and gives the student control over their own work.

    Please contact me if your child has speech sound difficulties.
