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.

    AAC Systems and Speech and Language Development

    Introduction

    I see a lot of minimally speaking or non-verbal children in my practice. Some children are autistic and others are severely challenged with motor planning and some are both. Some children are simply delayed in their spoken language for reasons that we don’t quite know yet.

    Regardless of the causes, what is always apparent pretty quickly is that apart from the odd gestures or Makaton signs (mainly ‘more” ‘finished’ and “biscuit) we don’t have a robust alternative for speech in place. Instead, what we often have is a child with lots of frustration and tantrums and some behaviours we really don’t want like: hitting, biting, pushing, grabbing and often throwing… There are others, too many to mention, but we don’t enjoy watching our children in these states. And we are often fearful of what might happen next if we don’t find a way to calm our child.

    Fear not

    In my work, before I get to offer an alternative means of communication, I often have to work with a fair amount of resistance on the parents’ side as parents tend to feel that allowing such a system into their lives will prevent their child from speaking. They fear that their child will so enjoy pressing those buttons that they will become lazy and not talk at all.

    I totally get it!

    Parents often feel overwhelmed by the task of getting their own heads round how to use AAC, either in paper form or a computerised system. This can be a great turn-off for lots of people who feel they are not very “techy” – like myself actually! Indeed, it is true to say that I resisted operating in this field for a long time as I didn’t feel able to navigate electronic devices. But fear not. Truly, most systems are very user-friendly. The support is great. And I have managed to become quite proficient in one or two of these systems, through using it daily. It really is as simple as that.

    Alternative and Augmentative Communication (AAC)

    There is plenty of research on the efficacy of Alternative and Augmentative Communication (AAC). It is now very well understood and proven that, once we introduce our child to a good, attractive way of communicating that they can actually do, in time children who can speak will speak. Speaking is more effective than any AAC system. It is more versatile, more fun, and when human beings have discovered how to speak, most will do so in favour of any other system.

    Many children and adults, for many reasons, were never going to speak an awful lot, or with great difficulty. Or they were not going to like to speak. Or they were going to like to speak some times but not other times… And for all those people an AAC system is invaluable and a wonderful resource.

    Neuro-diversity affirming means that we do not impose one system of communication on our children (speaking with our mouth) only because it is the one we are using and most people we know too.

    Of course, we want the best for our children, and we want them to have the easiest and most straight forward existence on Earth. Of course we do. Speaking with our mouth does help with that. But we must come to understand that not all children and people feel like that and they struggle to use their mouth for talking.

    Personal experience

    I have difficulties understanding this myself, I will be very honest here. And I will say that – shoot me down in flames SLT fraternity – but I am learning to accept that using an AAC system proficiently is a very good alternative for when speech is not coming. I am learning to accept that some people are perfectly able to speak, and might do so but not always and only when conditions are right. I came into the profession as a speech therapist with the idea that I would help anybody that came to me to speak with their mouth. But I have changed my stance on that and now am happy to help anybody that comes to me to communicate most effectively with whatever works for them. I will always try for speech if I can … Just because it’s easiest!

    Acceptance

    Now I will equally celebrate a child pointing to a symbol or making a sign for something. It is a fantastic moment when it happens for the parents and me and the child! And we can always hope for more speech to come as we go. Nothing wrong with our aspirations, is there?

    The basic premise is this: accept any mode of communication as valid, as long as your communication partner understands what it means. Don’t require individuals to repeat themselves in another modality. Do model the response in the modality you are trying to teach. So, a child can point to a symbol and I will respond with speaking (with my mouth) but I will also respond by pointing to a symbol because that way I am signalling that both are ok and that I have understood and am encouraging the person to say some more.

    Here is some research;

  • A Day In The Life Of An Independent Speech And Language Therapist

    A Day In The Life Of An Independent Speech And Language Therapist

    A Day In The Life Of An Independent Speech And Language Therapist

    I often get asked how many clients/children I see per working day or what my working day/life looks like. I always reply that every day is different, which is true, but there is a sort of average working day which looks a bit like this:

    I usually start preparing for my first client of the day at around 9.30 am: I clean the room, wipe down all the toys and materials (that’s if they are coming to my clinic room) and then it takes me about 30 minutes to select and sometimes make suitable materials, games and activities for the child’s therapy programme. Client arrives at 10.30 am and the fun begins. They leave around 11.30am, and the cleaning and wiping down starts again – yes it’s the pandemic but to be fair I would do this anyway. I quickly write up my notes and send home work to the client via email. Now it’s 12 noon and I start preparing for the next client at 12.30 pm. This might be online parent-child interaction coaching and so I need different materials and activities that are suitable for teletherapy. We finish around 1.30 pm and I will write up my notes before having some lunch.

    Lunch tends to not be around 30 minutes. Around 2.00 pm I start prepping again for the next client: selecting activities, going over their last session, making sure I have everything I need to start at 2.45pm – we finish at 3.45pm, I write up my notes and then have a cuppa. The next client might be more on-line coaching or a child coming to see me: room cleaned and tidy, materials and activities prepared: client arrives at 4.30 pm and we finish at 5.30 pm. I clean the toys again, write up my notes and it is 6.00 pm ready for dinner. So that was four clients between 9 am and 6pm allowing for preparation, aftercare, cleaning and coffee and lunch.

    Other days I might see three clients and do more admin like ordering toys or books or teletherapy activities, or making materials (we therapist make tons of materials, we’d put Blue Peter to shame!) Sometimes I do two home visits, one in the morning and one in the afternoon – the travelling/parking in London is so time consuming that it really reduces the number of clients I can see which is why I don’t do many of those.

    I hand pick my clients to make sure that we are a good fit, and my service is bespoke: no one client gets the same treatment as another; each client is unique, usually very well-known and always highly valued. That takes time and means that in reality each client gets about 2 hours of my time, that is the actual session plus all the preparation and aftercare.

    I love this way of working and would not ever want to return to seeing tons of clients each day, not knowing any of them really well, due to high caseload numbers, staff shortages and an overload of administration.

    My way of working affords all my lovely clients the help they need to be able to feel empowered and to then support their children to make progress; when working with children they make the best progress they can make, fulfilling their potential. My lovely reviews and testimonials tell me that my clients appreciate the extra attention.

  • 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.

    A bite-sized guide to Speech and Language Therapy: feeding and swallowing

    What is a Speech and Language – Feeding Therapist?

    You’ve probably heard of speech therapists helping people who stutter or struggle to pronounce words. But did you know that they also work with children and adults who have problems with eating and swallowing? This specialised area is called Speech and Language Therapy: Feeding and Swallowing, or Dysphagia Therapy.

    Why does a Speech Therapist help with eating and swallowing?

    The mouth, tongue, and throat are all involved in both speech and swallowing. When there’s a problem with any of these parts, it can affect both your ability to talk and to eat. For example:

    • Weak tongue muscles: Can make it hard to chew food and to form sounds.
    • Difficulty coordinating swallowing: Can lead to choking or aspiration (when food or liquid goes into the lungs).
    • Sensory issues: Can make certain textures or tastes feel unpleasant or overwhelming.
    • Communication: If we are not able to express ourselves we are likely to have difficulties during daily mealtimes: how do we ask for ‘more’ of something, how do we say we have had enough or we don’t like a particular food?

    How does a Speech and Language Therapist help?

    Our work involves a combination of assessment and therapy. We carefully observe how your child feeds, eats and swallows, and we look into your child’s mouth to help us see what the cause of the difficulties are: could be a very highly-arched palate, it could be a very flaccid/low tone tongue, it could be poor dentition. Then, we create a personalised treatment plan to address your specific needs.

    Here are some of the things we might do:

    • Teach swallowing techniques: We can help your child learn strategies to improve or facilitate a safe swallow.
    • Recommend dietary modifications: We may suggest changes to your child’s diet to make it easier to eat and swallow.
    • Provide sensory therapy: If your child has sensory needs we can help your child become more comfortable with different textures, tastes, and smells.
    • Work on oral motor skills: We can help to encourage more effective chewing, or drinking skills, or we can help your child to close his/her mouth more during chewing or drinking from a straw.
    • Collaborate with other professionals: We often work closely with doctors, nurses, occupational therapists, and dietitians to provide comprehensive care.

    What kinds of problems do Speech and Language Therapists help with?

    We see a wide range of feeding and swallowing difficulties, including:

    • Delayed feeding: Children who are slow to develop feeding skills or who have difficulty transitioning to solid foods.
    • Tongue-ties: Babies can have significant difficulties with feeding when the tongue is very tightly tethered to the floor of the mouth.
    • Refusal to eat: Children who refuse to eat certain foods or textures.
    • Aspiration: When food or liquid goes into the lungs, which can lead to pneumonia and other serious complications.
    • Chewing difficulties: Problems with chewing food, such as difficulty breaking down food or keeping food in the mouth.
    • Swallowing difficulties: Problems with swallowing, such as feeling like food is stuck or choking.
    • Neurological conditions: Conditions like cerebral palsy, down syndrome or other genetic syndromes can affect feeding and swallowing.
    • Developmental delays: Children with developmental delays may have difficulties with feeding and swallowing.

    Is there hope?

    If your child is struggling with feeding or swallowing, know that there is help available. Speech and Language Therapy can make a significant difference in your and your child’s quality of life. We’re here to support you every step of the way.

    Remember, you don’t have to suffer in silence. If you’re concerned about your child feeding or swallowing, please reach out. You can find a Speech and Language Therapist with a Feeding/dysphagia qualification near you via www.asltip.co.uk or contact me.

  • Speech sound disorders

    Kids Speech Therapist London
    Speech Sound Disorders

    Treatment Approaches – A Typical Session

    There are various great ways to treat speech sound disorders and I use all the approaches available selectively; I decide what works with each individual child and I also vary the approach depending on the child’s frame of mind at any given time during my session.

    Some of the approaches are more “drill-based” and require a child to be able to pay attention and really participate actively in the therapy, and this is what I am showing you today with this video clip.

    My little student here has been working with me for some time and from only saying a handful of words which were not very easy to understand he has come a long way. He does have some features of Verbal Dyspraxia which I shall briefly outline here:

    • Making sounds in general is a struggle, especially when asked to copy certain sounds, example: ‘can you say: a ee ou oo?”
    • Repeating sound sequences or words sequences is hard, for example: “say p-t-k in sequence” or “say fish chips fish chips fish chips
    • When saying the same word again and again, different mistakes can be heard
    • Intonation difficulties: speech sounds monotonous
    • Vocabulary is very limited

    Some therapy approaches are more play based, for example the Core Word method: here we pick a few words at a time which are very significant to the child and therefore highly motivating to try and say. These could be characters of Pokemon or Minecraft for example, or simple words like “GO!”

    When you watch the video you will see that I use a lot of visual prompting, such as showing him where the tongue is moving to or from. I do this with my index finger and this approach is called Tactile Cueing or “Cued Articulation”. Part of the approach is to give a visual prompt and then reduce the prompt as the learner is more able to produce the correct sounds. Once he can produce the sound on its own, we quickly move to the sound within a word.

    I do mix and match my approaches and in fact here I am drilling but I also use the Core Word which for him (YELLOW) — it’s his favourite colour and I happen to have quite a few good games where a YELLOW something or other can be asked for….. WHO KNEW!? 🙂

    Are the Gestalts I model easy to mix and match later on?

    Image by bearfotos on Freepik

    Here are some examples of great phrases and Gestalts that we could use:

    • Let’s get a banana / Let’s go out / Let’s play lego / Let’s go see daddy
    • That’s nice! / That’s really good! / That’s a green one / That’s a submarine
    • Need more help / Need a wee wee / Need that / Need to run
    • How about a biscuit / How about a cuddle / How about watching tv
    • We love bananas / We love a monkey / We love a cuddle

    Why or how could these examples be mixed and matched?

    You can see I have given several examples for each, that is how later a child can take one chunk (let’s) and add another (go out) or (need) + (go out).

    What about our own grammar? Should we be using grammatical phrases?

    In general for NLA 1 (Natural Language Acquisition stage 1) we want to use short phrases and keep them quite generic, something like:

    ‘Let’s go’ or ‘let’s play’ and pick 2-3 phrases per communicative function (see next point below).

    And if we are going to say longer sentences, for example: ‘let’s go and feed the ducks now’, then we should do so with good grammar and really varied intonation. It sometimes helps me to make up a little song/jingle on the spot that has a lot of intonation, more than I would perhaps use just by speaking.

    How many varied communicative functions do we cover with our modelling?

    We want to model a variety of Gestalts other than just requesting for example. In general, we are looking at our child having one or two Gestalts in the following areas before they are ready to move on into stage 2.

    These are the most common ones I see in my practice:

    • Requesting ‘want a banana/biscuit’ ‘Wanna play ball’
    • Transitioning: ‘what now?’ ‘what next?’
    • Ask for help: ‘need help’ ‘help me’ ‘mummy help’
    • Commenting: ‘it’s big’ ‘it’s red’ ‘it’s fast’ ‘too loud’
    • Speak up for self: ‘not that one’ ‘go now’ ‘stop it’

    Is the Gestalt I am modelling meaningful to my child?

    We don’t use all available Gestalts for every child. It has to be meaningful to the individual and has to match their interests. If our child is a big fan of feeding the ducks in the park then we can think about Gestalts like:

    • I see ducks!
    • They’re over there
    • Let’s feed them?
    • Let’s get some seeds
    • They’re coming!
    • They want food / They wanna eat!
    • That’s a big one
    • It’s so hungry
    • It loves the seeds!
    • No more! All done! Finished! Let’s go home

    What is my child actually trying to tell me?

    We have to be become word/phrase detectives! Is the phrase/script/Gestalt they are using right now actually meaning what they said or does it mean something else, and if so, what?

    Here is an example from my own personal experience in my practice:

    The little boy I was working/playing with was building a tall tower with blocks. When it finally fell with a great big bang he said in a sing-song voice ‘ring-a-ring-a roses’ … then he began to collect the blocks again to make a fresh tower. I sat there and thought: why ‘ring-a-ring-a roses’? What does that mean in this context? I then sang the song (silently) to myself with my detective hat on and realised as I came to the end that it finishes with ‘we all fall down’! it was a real AHA!!! moment for me as I saw right there what the meaning of his Gestalt was. He sang the first line of the song to say ‘all fall down!’

    So realising this I waited for the next tower to fall, and there it was again, he sang the first line of the song. I replied thus, copying him at first:

    ‘RING-A-RING-A ROSES – WE ALL FALL DOWN!…

    FALL DOWN

    WE LOVE IT FALLING DOWN.’

    The process to find what we should say is not always straight forward or easy at all, and often we don’t quite know in the moment what our child is trying to say. But we can try and get to know their interests and then gradually we do know more and more what the meaning behind the Gestalt is or could be.

    What pronouns should we use?

    This can be a tricky one.

    We don’t want to use language that uses the pronouns ‘you’ or ‘you’re’. The reason is that our child will likely copy us exactly as we have said it. Therefore, using pronouns ‘you’ and ‘you’re’ will then sound wrong.

    Always try to model language that is from the child’s perspective or in other words how they would say it if they could.

    Alternatively, you can model using WE or US. For example, if the child is tired, rather than saying ‘you are so tired’ model language from his or her point of view: ‘I’m tired’ or ‘let’s go have a lie down’.

    There is so much more to talk about. Stay tuned for a blog on NLA stage 2 coming soon.
