Chaining: A powerful tool for phonological development

ByLondon Speech and Feeding
| |

Understanding chaining

Chaining is a therapeutic technique I like to use in my speech therapy work with children who have Childhood Apraxia of Speech (CAS) or phonological speech sound difficulties. It helps to break down a complex target behaviour into smaller, more manageable steps. By systematically teaching and reinforcing each step, I can help my students achieve their communication goals.

There are two types of chaining: Forward and backward chaining

Today I am going to show and talk about backward chaining. This technique involves starting with the last step and working backward to the first. This approach can be particularly effective for children with persistent speech sound difficulties where combining consonants into clusters, such as /BL/ or /FR/ or /SHR/ is very difficult.

Backward chaining allows my student to experience immediate success and build his confidence.

In my video I show you how I applied backward chaining to the words ‘Shriek’, ‘Shrub’, ‘Shrimp’ etc

My student struggles with both the /SH/ and the /R/ sounds and we have been working on both sounds for some weeks now. He has mild Childhood Apraxia of Speech and he has difficulties with coordinating his tongue movements, breathing and using his jaw effectively to make words. His sound repertoire has grown a lot since we started working together last year. Today in this session I show you how we pulled both the sound /SH/ together with /REEK/ to make ‘SHRIEK’. I love using the pictures and therapy materials from Adventures in Speech Pathology.

This is also part of the Complexity approach which I will explain in a separate blog post.

  • Step 1 (not shown in the video): I explain what the word means; I find that when my student understands what a word means he is much better at saying it. It increases his confidence and motivation to say a word that he knows the meaning of. Often this student does not tell me that he does not know what a word means, so I always remind myself to check that out first.
  • Step 2 (not shown in the video): We do a little rhyming game and think about what any one word rhymes with: ‘Shriek’ – ‘meek’, ‘weak’, ‘seek’.
  • Step 3: I show my student that there are two parts to this word /reek/ and the sound /SH/.
  • Step 3: We practise the easier part: /reek/ /reek/ /reek/.
  • Step 4: We add the /SH/ sound and pull it together to make our target word ‘Shriek’.

/REEK/ /REEK/ /REEK/ + /SH/ = ‘SHRIEK’
/RUB/ /RUB/ /RUB/ + /SH/ = ‘SHRUB’
/RUG/ /RUG/ /RUG/ + /SH/ = ‘SHRUG’

By breaking down the word into smaller, manageable steps, my student can focus on each syllable individually, get that right and then gradually build up to the full word. This approach can help to reduce frustration and increase motivation.

Forward chaining

Forward chaining is the same process but in reverse: we start with the front sound or syllable and work forward towards the next/last part of the word:

/SH/ + /REEK/ = ‘SHRIEK’
/SH/ + /RUB/ = ‘SHRUB’
/SH/ + /RUG/ = ‘SHRUG’

Benefits of chaining

  • Increased motivation: By starting with the last step, my student experiences success, which boosts his motivation to continue trying to say the word and trying other words.
  • Reduced frustration: Breaking down the target behaviour into smaller steps can make the task less overwhelming, reducing frustration and anxiety.
  • Improved confidence: As the little learner masters each of the step, his confidence and self-esteem increases. Again, this leads to increased motivation.
  • Faster learning: By focusing on the final step first, and practising lots of chaining (forward and backward), a student can quickly learn to generalise to other words.

Backward chaining (and forward chaining) is a really great tool for teaching complex speech sounds and words to children with phonological disorders.

Watch out for my next blog which is all about the complexity approach in Phonology.

    Tongue training: Why tongue placement matters for clear speech

    ByLondon Speech and Feeding

    As speech and Language therapists (SLTs), we know that where your tongue goes, so goes your sound. This blog post will explore why tongue placement is so vital for speech correction and how we use tools and techniques to help our clients find their ‘sweet spot’ for sound production.

    Let me show you here a little video clip where I am using my dentist’s mouth/teeth model to help my clients navigate their tongue movements.

    The tongue: A tiny muscle with a big job

    The tongue is a small but mighty muscle. It’s incredibly versatile, playing a key role in eating, swallowing, and, of course, speaking. For each speech sound, the tongue, along with the lips and jaw, needs to move to a very specific spot. Think of it like a dance: every part of your mouth has a choreographed movement to produce the correct sound. If the tongue is out of sync, the sound comes out muffled, distorted, or just plain wrong.

    The trouble with our tongue movements is that most of us never think about how the tongue has to move and what it does to: swallow, chew, drink, suck and speak. Most parents when asked to think about their own tongue placement for say the /S/ sound are completely lost as to what their tongue is doing. Yet, of course, they produce a perfect /S/ and perfect speech in general. The same goes for swallowing. When did you last think about what happens in your mouth when you swallow? I bet you have not thought about it. We ‘just do it’, right?

    Why is tongue placement so important?

    Accurate tongue placement is the foundation of clear articulation. When a child struggles with a particular sound, it’s often because his or her tongue isn’t quite reaching the right spot or moving in the correct way. For example, the /S/ sound requires the tongue to be slightly raised and positioned behind the top teeth, creating a narrow channel for air to flow through. If the tongue is too far forward, you might get a /TH/ sound instead. If it’s too far back, the /S/ can sound muffled.

    Visual aids: Our secret weapon

    We SLTs love our visual aids! They’re incredibly helpful for showing clients exactly where their tongue needs to be. Here are some of our favourite tools:

    • Mirrors: Mirrors provide instant feedback. Clients can see their tongue’s position and make adjustments in real-time. We often use hand mirrors or even the mirror on a compact for quick checks.
    • Tongue depressors: These simple tools can gently guide the tongue to the correct position. We might use them to show where the tongue tip should rest for the /L/ sound or how the sides of the tongue should touch the molars for the /K/ and /G/ sounds.
    • Diagrams and models: Pictures and models of the mouth can help clients visualise the tongue’s movements. We might use a cross-section diagram of the mouth to show how the tongue forms different sounds.

    Beyond the tongue: The jaw’s role

    While the tongue takes centre stage, the jaw plays a supporting role. It provides a stable base for the tongue and helps control the opening and closing of the mouth. Sometimes, jaw stability is an issue, and we might use techniques to help clients find a comfortable and stable jaw position.

    Making it fun and engaging

    Learning correct tongue placement can be challenging, but we make it fun! We use games, stories, and playful activities to keep clients motivated. For younger children, we might use silly voices or pretend to be animals. For older children, we might incorporate their interests, like using a car analogy for tongue movements.

    The takeaway

    Correct tongue placement is essential for clear speech. By using visual aids, interactive techniques, and a bit of creativity, we can help our clients master their speech sounds and communicate with confidence.

  • Explore the relationship between poor speech, language and communication and literacy skills

    ByLondon Speech and Feeding

    Communication skills are critical in all areas of communication throughout childhood and into adulthood. They are needed for understanding, narrating, making predictions and to develop social skills, for example in understanding everyday language or talking in the classroom or socialising with peers. Children with communication needs can experience low self-esteem, potential behavioural difficulties, lower school attendance and attainment.

    Communication skills have a strong impact on literacy. Let’s look at some of the facts:

    • 50% of children with language delays also have challenges with literacy (Burns et al, 1999).
    • 73% of poor readers in year three had a history of difficulties with phonemic awareness (the ability to hear, identify and manipulate sounds) or spoken language in pre-school (Catts et al, 1999).
    Speech Therpaist in London

    The effect of expressive language on spelling and reading

    The ability to read is very much dependent on competent language skills. Furthermore, a limited vocabulary will also have an impact on literacy skills. The more we know about a word, the easier it is to retrieve, recall, understand and use. So, if a young person has a poorer vocabulary, it’s likely that they will not have the same decoding skills as a peer with a richer set of vocabulary. By decoding we mean the ability to apply knowledge of letter-sound relationships including pronunciation of words. Decoding is a vital skill used in literacy.

    Whilst learning to read is a key skill, it’s important to remember that a solid foundation is needed for success. We need to ensure that no steps are missed, otherwise there will be gaps in knowledge.

    As your child moves further through the education system, they will be “reading to learn”. This is where young people with poorer language skills may show literacy difficulties (for example, reading comprehensions become more challenging, and their expressive language skills impact on their written abilities).

    When should I seek advice or support?

    Always seek the advice from a qualified professional such as a Speech and Language Therapist. You need appropriate advice for the age and stage of your child’s development and early intervention is of course key to success. It is never too late to ask for advice. The earlier you seek support, the better the outcome for your child in all areas (language, literacy, and emotional well-being).

    Have you still got unanswered questions? Contact me here and we can have a look at your child’s phonemic awareness, auditory processing skills, verbal understanding and assess his/her ability and likelihood of reading and literacy struggles. If we find that your child has dyslexia I can refer on to a specialist colleague who can help you further.

    Four struggles parents face when out and about with children with speech, language, and communication difficulties

    ByLondon Speech and Feeding

    You (as parents) often describe yourselves as being under constant pressure and stress when looking after your children and young people with Special Educational Needs and Disabilities (SEND). You may find going out to do the simplest of tasks a challenge. And you will try to avoid social situations out of fear and anxiety. One of the most important factors to you is having like-minded people who understand your position as a parent with a young person with additional needs. Let’s look at some of the challenges you face and how I can support you and your family.

    1. Challenging behaviour and going out to the shops

    When your child displays challenging behaviour and won’t go into a shop without buying a toy that they insist on having, it can be tough on your family. You see people around you staring as you try to manage the situation. They do not understand the pressures you face, or that the simplest of tasks are a huge challenge.

    I can support you by giving strategies to use when out and about. I know that using visuals is important for your child. They may not understand or take in language when they are in a heightened state of anxiety or feeling overwhelmed. You could print pictures of the places you’re going to and put them on an easily accessible chain. Then you could use that chain when out and about at the shops. You may want to introduce a visual timetable at home. That way your child or young person understands where they are going. This may lessen their anxiety and subsequent behaviour.

    2. Your child is not able to communicate their needs to an unfamiliar communication partner

    When your child has difficulty communicating to an unfamiliar person it can be hard to manage. You feel yourself explaining your situation repeatedly. I can provide your child with individualised strategies or communication aids which support your child to communicate with both familiar and unfamiliar communication partners. We’ll work together to find which communication methods work in different situations and how your child will use these to help their independence.

    3. Being overwhelmed

    Your child or young person may easily be overwhelmed which may contribute to behaviour changes. I’ll work with your family to understand what the behaviour means, looking at what happened before and what happened afterwards. We’ll not only look at the behaviour but at the environment as well. This can inform how you can support your child or young person in the future, to reduce sensory stimuli (if needed) and for them to feel emotionally regulated.

    4. People avoid engaging with you

    One of the hardest things as a parent is for others to avoid you. You see them crossing the street because they don’t know what to say to you. All you want is them to accept you, to maintain your identity as a person and not as a SEND parent. I can support you emotionally. I can give you advice on local support networks where you can find other parents in a similar situation.

    We know the stresses that being a parent with a child with SEND comes with. Please know I am always here to support you, to find solutions so that when you’re next out and about. Your experience will be a little easier and you’ll feel less isolated.

    Improve your child’s communication, confidence, reduce overwhelm and feel supported here.

    Discover more about Verbal Dyspraxia

    ByLondon Speech and Feeding

    What is Verbal Dyspraxia?

    Apraxia or dyspraxia is a difficulty in motor planning, which sometimes can be seen in both gross and fine motor skills, as well as speech. Gross motor refers to difficulties in coordinating the whole body (e.g., bumping into things frequently, often falling over hurting themselves or others through being “clumsy” or unsteady). Fine motor movements refer to smaller, more precise movements (e.g., difficulties doing anything with their hands such as holding a spoon or pen).

    Verbal dyspraxia

    In Dyspraxia of Speech, instead of seeing a coordinated smooth way of talking, we see the articulators (tongue, lips, cheeks) and voice coordinating very smoothly. The voice can be very quiet or very loud. Muscle tone can be weaker at times. Speech sounds are very unintelligible, with a flat voice that can sound forced. It may be that the timings of verbalisation appear random and that children can say a certain word once and never again. This is often what we hear from parents.

    It is interesting to note that many of our autistic clients are either non-speaking or are reluctant speakers. Sometimes they say a word once and then never again. Others say lots of words but the words are very hard to make out. Did you know that about 40% of autistic people have verbal dyspraxia? (Richard, 1997). Because the problem is one of motor planning, not of automatic motor execution, once a plan has become automatic, it is easier to get back to it and this is why we often see repetitive patterns that can be called ‘stims’ (Marge Blanc, 2004).

    How can Speech and Language Therapy help?

    Children with verbal dyspraxia can make great progress!

    We provide frequent and appropriate speech movement opportunities and with time and the right support, children will move forward and begin to speak more fluently and with greater intelligibility. It is important to know this can take time.

    We provide Oral Motor Therapy using a variety of approaches to practise breathing, vocalising on the outbreath, and sequencing our speech movements.

    We design carefully tailored programmes focusing on words that have a lot of power (e.g., NO, GO, UP, IN, OUT, LET’S GO, STOP).

    We offer shared enjoyment, and laughter. This helps a child find their voice. Other ways of finding our voices include singing or humming, or even yelling/shouting!

    The most difficult phase of verbal dyspraxia is initiation, that is to start talking, to start producing a word. Frequent “automatic” repetition supports children with initiation because it removes the element of “thinking to start”. I often ask a child to repeat a word 5-10 times (with rewards at the end. A little game works well). You can see that with repetition the act of initiating is taken out of the equation as you are “on a roll “as it were.

    Once a child starts to find their voice, we will be able to hear them talk lot… And if we give them credit and presume that what they are saying has meaning, we will find in time that their words become clearer and more intelligible. If we listen carefully, we can detect real words and phrases.

    Using AAC in daily life

    ByLondon Speech and Feeding

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

    What is AAC in a nutshell?

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

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

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

    Modelling is KEY: Showing, not just telling

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

    Here’s why modelling is so vital:

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

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

    Low-tech AAC in action: Everyday activities

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

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

    1. Getting ready for nursery

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

    Activity example:

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

    AAC mornings symbol examples

    2. Breakfast Time

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

    Example symbols:

    AAC meal times symbol examples

    Activity example:

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

    3. Catching the Bus

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

    Example symbols:

    AAC catching the bus symbol examples

    3. Being on the playground

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

    AAC playground symbol examples

    Activity example:

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

    Beyond the symbols: Key takeaways

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

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

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

    Explore activities for Gestalt Language Processors to aid communication

    ByLondon Speech and Feeding
    Speech Therpaist in London

    When you have a child who uses Gestalts it is often difficult to think and adapt clinic activities into those to use at home. More importantly, you find that individualising your activities for your child who uses Gestalt are time-consuming. But you value its importance for their communication development.

    You feel so busy, you are taking them to other appointments, or trying to get through your daily activities, all whilst still ensuring your child’s emotional needs are met. You know life should not get in the way of your child’s therapy activities at home, but it does. We know your spare time is precious and limited, so let us achieve your child’s or young person’s goals in the allotted time you have which meets their way of learning (using Gestalts).

    We wanted to support you by exploring items which you may have at home, and we will give you some key phrases which you can start to model with your child. Whereas our last blog introduced the idea of gestalt language processors, we are now developing ideas to give you the tools to implement activities at home. We recognise how overwhelming it may feel, and this is one of the reasons to make activities as straight forward as possible. Therapy does not need to be complicated; it just needs to be carried out on a regular basis.

    Explore the samples I’ve created to give you an idea of how this might look but please consult with a Speech and Language Therapist who knows about Gestalt Language Processing so that you can work together to develop great home activities for your child.
