Seeing sounds: How visual gestures boost speech sound learning

ByLondon Speech and Feeding
| | |

Learning to produce new speech sounds can be a complex process for young children, especially those facing challenges with speech sound disorders or motor planning difficulties. It’s not just about knowing what a sound ‘should’ sound like; it’s about figuring out where to put your tongue, how to shape your lips, and how much air to push out. This is where the power of visual gestures comes in – literally helping children see how to make sounds.

As speech and language therapists, we frequently use visual cues and hand gestures to teach articulation. These techniques are incredibly effective, particularly when a child is struggling with the motor planning aspect of speech production.

In the video clip above you see me teaching

  • the /SH/ sound: the hand makes a C-shape and moves forward showing both how the lips are positioned and the air flowing forward
  • the /S/ sound: the index finger shows a snake like movement going forward- also showing the air flow again
  • the /W/ sound: my right hand moves forward and fingers splay out showing that the lips open up at the end of the sound
  • the /K/ sound: my finger points to the back of my throat where the tongue needs to raise.

An overview of motor planning for speech – what do we mean by that?

Think about learning to ride a bike or play a musical instrument. You don’t just know how to do it instantly. You have to plan the movements, practise them, and make adjustments. Speaking is similar! Our brains must:

  1. Plan the sequence of movements needed for each sound and word (e.g., /B/ requires lips together, then release, while /T/ requires the tongue tip behind the top teeth, then release).
  2. Execute those plans rapidly and precisely.

For some children, especially those with conditions like Childhood Apraxia of Speech (CAS) or other severe articulation disorders, this motor planning process is disrupted. They know what they want to say, but their brain struggles to send the correct, consistent messages to their articulators (lips, tongue, jaw, velum). This can make speech sound learning incredibly frustrating.

Why use visual gestures?

Visual gestures provide an additional, powerful sensory input that can help bridge the gap between knowing a sound and producing it. Here’s how and why they are so beneficial:

1.      Providing a visual map:

  • How it helps: Many speech sounds are ‘hidden’ inside the mouth. It’s hard for a child to see where their tongue needs to go for a /K/ sound (back of the tongue to the roof of the mouth) or a /T/ sound (tongue tip behind teeth). A simple hand gesture can visually represent this mouth movement. For example, a hand gesture for /K/ might involve sweeping the hand back towards the throat, while for /T/, it might be a tap on the chin.
  • Why it works: Children are highly visual learners. Seeing a physical representation of an abstract mouth movement gives them a concrete ‘map’ to follow, making the process less mysterious and more manageable.

2.      Enhancing motor planning and memory:

  • How it helps: When a child simultaneously moves their hand (the visual gesture) and attempts to make the sound, they are engaging multiple sensory systems (visual, tactile, proprioceptive – body awareness). This multi-sensory input strengthens the neural pathways associated with that speech sound.
  • Why it works: This multi-modal learning helps to solidify the motor plan for the sound in the brain. It’s like having more ‘hooks’ to hang the information on, making the sound easier to recall and produce consistently. The gesture becomes a built-in reminder.

3.      Reducing cognitive load:

  • How it helps: Instead of just hearing the sound and trying to figure out the complex motor sequence, the child has a visual cue to guide them. This reduces the mental effort required to decode the sound production.
  • Why it works: When cognitive load is lower, the child can focus more effectively on the specific motor execution of the sound, leading to faster progress and less frustration.

4.      Increasing engagement and success:

  • How it helps: Gestures can make therapy more interactive and fun! When a child successfully produces a sound with the help of a gesture, it’s a tangible victory.
  • Why it works: Success is a powerful motivator. When children experience success, they are more likely to stay engaged, participate actively, and feel more confident in their ability to learn new sounds.

5.      Supporting self-correction:

  • How it helps: Once a child learns the gesture associated with a sound, he or she can use it as a self-monitoring tool. If he or she makes an error, he or she can use the gesture to remind himself or herself of the correct mouth position or movement.
  • Why it works: This promotes independent learning and reduces reliance on constant adult prompting.

Conclusion

The journey of speech development can be challenging, but visual gestures offer a powerful and effective tool for teaching new sounds, especially when motor planning is a factor. By providing a clear visual map, strengthening motor memory, reducing cognitive load, and fostering engagement, these gestures pave the way for clearer communication and greater confidence. If your child is struggling with speech sounds, consider talking to a Speech and Language Therapist to get guidance on how visual gestures might be incorporated into the therapy plan. Because sometimes, seeing truly is believing (and speaking!).

    Books, Stories And Colourful Semantics

    Many of my students have difficulties telling stories. When looking at a book together, even books they love and have seen many times, they often struggle to understand what they are reading and cannot therefore retell the story in any sequence. A great method I often use with those students is called Colourful Semantics.

    What is Colourful Semantics?

    Colourful Semantics is an approach aimed at helping children develop grammar and meaning of phrases and sentences. We help children identify WHO is the subject in a story, what is he/she/it DOING to WHAT and WHERE. There are lots of colour coded stages but we tend to start with the basic 4:

    WHO = ORANGE

    DOING = YELLOW

    WHAT = GREEN

    WHERE = BLUE

    Once a student is accomplished at this level, we move on to different colour codes for describing words (adjectives), connecting words (with/together/and/therefore) feeling words (PINK), timing words (BROWN) eg. when, tomorrow, last week etc.

    Colourful Semantics is a really useful method and helps children to organise their sentences. It also helps me knowing how to guide a student in thinking about the story.

    The approach can be used with children with a range of Speech and Language Needs, such as:

    • Developmental Delay / Disorder
    • Autistic Spectrum Condition
    • Down Syndrome
    • Any other syndromes and related speech and language delays
    • General Literacy difficulties

    There are a wide range of benefits to using this approach and I use it in my therapeutic work with children of around 3 years plus. Below is a little video which shows how I use it with this student who has general language difficulties associated with Autism. One of the main benefits with this student is that seeing the Cue Cards helps her to use a much wider range of vocabulary than she would ordinarily generate. Her sentences are getting longer and she is more able to answer questions. In general, I find it useful to help with storytelling and to guide us through the story in a sequence.

    There are many on-line games these days that have incorporated the Colourful Semantics Approach. Once a child is familiar with the basic colour scheme then gradually the visual prompts can be reduced to using verbal prompts.

    Bilingualism – should I speak only English with my speech delayed child?

    ByLondon Speech and Feeding

    Introduction

    Bilingualism is a beautiful aspect of our diverse world. Growing up in a bi- or multi-lingual household is a wonderful gift, allowing children to communicate with a broader range of people and access many cultures.

    My own two children grew up in a bilingual German-English speaking household. They have both been so enriched by this experience, not only language- and learning-wise but of course also culturally: their world has always been so open and colourful. Growing up in inner London and having their German family and mum’s friends as well, this has been a wonderful experience. Both my boys speak German well (not quite like native speakers but like very good second language speakers) and both have very easily learned 3rd and 4th languages additionally when in secondary school.

    Whilst bilingualism has untold benefits, it’s not uncommon for bilingual children to take slightly longer to reach certain speech milestones. This should not be automatically mistaken for speech disorders but rather seen as a natural part of bilingual language development.

    Bilingualism and speech delays

    Sometimes, of course, we do see speech delays or disorders where a child’s speech development lags significantly behind their peers. We often see a delay in both languages equally, making it extra hard for to communicate effectively. BUT PLEASE KNOW the family speaking in multi-lingual languages never caused the delay/disorder!

    If there is a delay or a disorder any number of other reasons could have caused it, such as:

    • hearing impairments,
    • reduced phonological awareness,
    • sensory processing issues,
    • reduced attention and reduced joint attention,
    • neuro-developmental delays or difficulties,
    • general or specific learning difficulties
    • or sometimes other genetic factors.

    So, to say that the difficulty is due to a child being exposed to several languages is a red herring. (no offence to herrings!)

    Speech therapy

    Speech therapy can be powerful to help bilingual /multilingual children with speech delays unlock their full linguistic potential. By providing individualised assessments, targeted interventions, and involving families, speech therapy can bridge the gap between speech delays and bilingualism. It’s essential for the therapist and parents to work together to support the children in their unique linguistic journeys, helping them communicate effectively and thrive in both of their languages.

    Speak your home language at home

    Many parents report that they worry about speaking their home language at home and instead they have been focusing on just speaking English at home. They now rarely use their home language with their child. They fear that speaking a language other than English with their child will cause further delay and hinder their progress. All parents want the best for their child and often parents fear that their child won’t fit in or will be seen as ‘different’. So we can understand why parents feel that the English language is the only one worth having.

    But the opposite is the case: it is crucial to speak in both languages freely, both at home and outside the home! Both languages will benefit your child, no matter what the delay or difficulty is. Acquiring a ‘mother tongue’ or native language is absolutely vital for children to have a good, solid linguistic grounding on which to build other languages. Bilingual children may mix languages during speaking and parents may equally mix their languages. This does not hinder language development and is a natural part of linguistic development.

    Speak freely and naturally

    What is far more important than the question: ‘which language should I say this in?’ Instead think: ‘let me speak freely and naturally, let me respond naturally, in good intonation and let communication flow freely to the child.’

    Speech therapy can be a crucial resource for bilingual or multilingual children and their families.

    We work on targeted interventions to address speech and language difficulties, helping your child develop essential communication skills. For home practice between therapy sessions, we can recommend tailored treatment plans to help you help your child in daily life. Our input could be focusing on articulation, phonological awareness, attention and listening, vocabulary development and grammar.

    Family support is crucial in speech therapy. We like to work closely with parents to provide guidance and strategies for fostering language development in both languages at home.

    If you have any worries about your child being delayed in a bilingual or multilingual household do get in touch and we will be happy to support you in your journey.

    Halloween without the tears: Supporting children through the Spooky Season

    ByLondon Speech and Feeding

    For many families, Halloween is an exciting time filled with costumes, decorations, and sweets. But for children who are sensory sensitive, whether they’re autistic, have sensory processing differences, or simply find new experiences overwhelming, Halloween can feel like a night of chaos rather than fun.

    The bright lights, unexpected noises, strange textures, and social pressure to ‘join in’ can quickly become too much. The good news? With some thoughtful planning and gentle support, you can make Halloween a positive and manageable experience for your child.

    Understanding sensory overload

    Sensory overload happens when a child’s brain receives more sensory input than it can process. This might mean:

    • Costumes that itch, squeeze, or feel strange on the skin.
    • Loud sounds like doorbells, fireworks, or shrieking decorations.
    • Crowds and unpredictability during trick-or-treating.
    • Strong smells or tastes from face paint or unfamiliar sweets.

    When overloaded, children may cry, cover their ears, hide, run away, or ‘shut down.’ These reactions aren’t ‘bad behaviour’, they’re signs of distress. The goal isn’t to eliminate Halloween fun, but to adjust it to your child’s comfort level.

    Step 1: Choose costumes wisely

    Costumes are often the biggest trigger. Scratchy fabrics, tight seams, or masks that restrict breathing can be unbearable for some children.

    Try these tips:

    • Go sensory-friendly: Use soft, breathable fabrics and remove tags. Many retailers now sell sensory-safe costumes.
    • Test it early: Let your child wear the outfit around the house before Halloween. If it’s too much, simplify — maybe themed pyjamas or a favourite T-shirt with Halloween accessories.
    • Skip the mask: Face paint can be equally challenging, always test on a small patch of skin first. A comfortable headband or hat might be enough to feel ‘in costume.’

    Remember, participation doesn’t require perfection. Your child can still ‘be’ their favourite character without a full costume.

    Step 2: Plan your Halloween environment

    Before the big day, think about what parts of Halloween your child enjoys — and what might overwhelm them.

    At home:

    • Keep decorations minimal and predictable. Avoid motion-activated sounds or flashing lights.
    • Practise knocking at your own front door or saying ‘trick or treat’ with a trusted adult.
    • Have a ‘quiet space’ ready, a cosy corner or room where your child can retreat if things get too intense.

    If you’re going out:

    • Choose earlier, quieter times for trick-or-treating.
    • Visit a few familiar houses instead of the whole street.
    • Bring ear defenders or noise-cancelling headphones.
    • Have a clear exit plan if your child needs a break.

    Sometimes, watching from the window and handing out sweets can be just as enjoyable! it still offers social participation without sensory overload.

    Step 3: Prepare socially and emotionally

    Halloween involves a lot of unexpected social interaction: strangers at the door, unfamiliar greetings, and different rules.

    Help your child by:

    • Using visuals or stories: Read picture books about Halloween or make a short social story about what will happen.
    • Role-playing: Practise saying ‘Trick or treat!’ or handing out sweets in a fun, low-pressure way.
    • Labelling feelings: Explain that it’s okay to feel nervous or to take a break if something feels ‘too loud’ or ‘too much.’

    Children feel safer when they know what to expect. Predictability reduces anxiety and makes participation more enjoyable.

    Step 4: Rethink the treats

    Not every child enjoys sweets; some dislike sticky textures or strong flavours. Offer non-food alternatives like stickers, glow sticks, or small toys.

    If your child has feeding difficulties or oral sensitivities, it’s okay to opt out of the traditional treats entirely. They can still join in by giving treats or decorating treat bags instead.

    It’s also helpful to prepare your child that others might offer sweets they don’t want. Practising polite ‘no thank you’ responses can make these moments easier. (check out my symbol download for children who struggle to speak)

    Step 5: Celebrate your way

    Halloween doesn’t have to look like anyone else’s version. Maybe your family watches a ‘not-too-scary’ film, carves pumpkins, or does a flashlight treasure hunt indoors. The goal is joyful connection, not conformity.

    A calm, happy experience, even if it looks simple from the outside builds positive associations your child will carry into future celebrations.

    In summary

    Halloween can be full of sensory surprises, but with empathy, planning, and flexibility, it doesn’t have to end in tears.

    The more you adapt to your child’s sensory needs, the more they learn that they are safe, understood, and included not just at Halloween, but in every celebration.

    As with all things in speech and feeding development, progress starts with connection. When children feel regulated and supported, communication and confidence follow.

    HAPPY HALLOWEEN!

    The importance of child-led therapy

    ByLondon Speech and Feeding

    Child-led therapy is essentially what it says, therapy sessions that are directed by your child. You may think how can my child’s Speech and Language Therapist focus on goals if sessions are led by my child.

    Let us explain…

    Your child will be more receptive and motivated to take part in therapy if they have some form of input. E.g., they can choose what toys they want to play with, or how they want to play with the resources available. If sessions are child-centred then they are much more likely to engage and reach their goals, making intervention valuable. They will also be able to regulate their emotions, and use movement to support their need for regulation. E.g., some children like to jump whilst others like to run. As Speech and Language Therapists we need to use what is meaningful to your child to get the most out of intervention. By focusing on child-led therapy, we can build trust, which will allow us, in time, to use new techniques and activities that your child may enjoy. We want children to be themselves, to show their true personality. Therapy is about enhancing their skills in their own individualised way and child-led therapy allows for this.

    This way of working may seem daunting to some, but it doesn’t have to feel this way. Parents often feel if they are prepared then activities may go smoother. It might be the case, but perhaps it doesn’t give your child the opportunity for spontaneity. We’d like to suggest something that may lead to some surprises. Put out an activity that is your child’s favourite and then a completely new activity. Remember these activities don’t have to be complicated. Often, the simpler the better!

    So, no need to plan, just place two activities out and see what happens! Look out for anything which surprises you, which activity did they prefer? Do they have any sensory preferences? The freedom of choice is a wonderful thing to explore. So, just go with the flow!

    The kind of activities that are useful for child-led play can include:

    • Hide and seek
    • Cooking or baking
    • An Exercise ball
    • Small world play
    • Pretend play
    • Musical instruments (you could even have a go at making your own)

    Child-led therapy is a very useful resource. We have it at our fingertips. We don’t need special resources. You just need yourselves and your child! Sometimes, child-led therapy can be tricky to put in place. It sounds easy but is much harder in reality. So, make sure you give it time and reflect on your experiences. Ask yourselves ‘what went well’, and ‘what could be improved’. E.g., perhaps you gave your child time to lead to begin with, but you didn’t give them enough time to think about their options during the activity.

    How can parents become more child-led in the home environment?

    • Pause and use silence. This gives your child the opportunity to lead.
    • It’s perfectly natural to want to talk. Afterall, this is how adults maintain conversations. If you find yourself talking too much, count to ten! This will allow your child time to respond or initiate in the conversation or interaction.
    • Move down to your child’s level. It’s much easier to see what’s going on if you’re at the same height.
    • Videoing you and your child can really help you to see where your strengths lie. You’ll also be able to make minor tweaks to improve your communication during child-led play.

    Let’s relax about making EYE CONTACT already…

    ByLondon Speech and Feeding

    There’s been a long tradition with teaching staff and with Speech and Language Therapists working in schools that eye contact should be a goal. It is well known that Autistic individuals (whether that be children or adults) mostly avoid eye contact. Whilst it’s part of the way we communicate, it shouldn’t be used as a necessity for an individual who feels that it is uncomfortable. Whilst it does show that you’re listening and showing an interest, it’s not a fair expectation for neurodiverse children.

    Autistic children can find making and maintaining eye contact physically and emotionally uncomfortable as well as unnatural. It adds an extra layer of stress and has been reported to increase distractions rather than reduce them. Children who engage in conversations in their own way (i.e., with reduced eye contact) are not shown to suffer with schooling, work, or social interaction.

    By having fun through meaningful activities, I often experience that ‘BINGO’ moment (a phrase coined by Alex @meaningfulspeech) where the child is enjoying themselves and naturally makes eye contact. There is no demand on them, they are in a fun, engaging environment which suit their strengths and supports their needs.

    Following this, I often reflect on this question ‘Should we make eye contact as a goal?’

    It very much depends on the situation. If it places more demands on the child and becomes stressful. Then no. There are many strategies we can use which gain eye contact without placing extra demands on the child. We need to be mindful to adapt the environment and not place neurotypical expectations to meet the needs of neurodiverse children.

    How can you encourage eye contact without demand?

    • If you’re using toys, try holding them up to your eye level.
    • You can adjust your position, try sitting face to face during play.
    • Always get down to your child’s level. This might mean that you lay on the floor if your child is positioned in this way.
    • During play, waiting is extremely powerful. Before a key part of the activity, wait and see if your child looks at you. Remember silence is golden!
    • The best way I find is: do something unusual during play. It might be that you spray shaving foam with the lid still on. Or you bring out a wow toy and make it spin/light up or make a noise. A balloon can be good – see video clip. Use the excitement of the activity, and wait to see if you achieve that ‘BINGO’ moment.
    • Create opportunities when there are no toys involved such as during ‘tickles’ or ‘hide and seek’. Autistic children find it difficult to shift their attention between a toy and an adult. So by removing one option, you’re setting them up to succeed.

    Remember, it takes practice and time for you to develop these skills. Try one at a time and experiment, see which works best for your child. If you need speech, language or communication support or advice, I am always here to help.

    The hidden impact of mouth breathing and open mouth posture on speech and feeding

    ByLondon Speech and Feeding

    When most people think about speech or feeding difficulties, they picture the tongue, lips, or chewing skills, but how a child breathes at rest plays a surprisingly big role too.

    Mouth breathing and open mouth resting posture can quietly influence everything from how a child’s face grows to how clearly they speak, to how confidently they chew and swallow. It’s something many parents never think about, until they start noticing the subtle signs.

    Let’s explore why this happens, what to look for, and how to gently support better breathing and oral posture.

    Recent research supports this link between mouth breathing and speech difficulties. For example, a 2022 study by Alhazmi et al., published in the Journal of Pharmacy and Bioallied Sciences, found that 81.7% of children aged 9–17 who breathed primarily through their mouths presented with speech sound disorders. The study highlights how mouth breathing can significantly influence orofacial development and articulation patterns.

    💨 Why we’re designed to breathe through our nose

    Our bodies are made for nasal breathing. When we breathe through the nose, the air is filtered, warmed, and humidified before reaching the lungs. The tongue naturally rests against the roof of the mouth, the lips close gently, and the jaw stays relaxed, all of which encourage healthy oral development.

    In contrast, mouth breathing often means the tongue rests low in the mouth and the lips stay apart. Over time, this posture can subtly reshape how the muscles and bones of the face grow.

    Children who breathe through their mouths most of the time may develop:

    • A longer face and narrower palate
    • Forward head posture
    • Slightly open lips and low tongue position at rest
    • A tendency toward drooling or noisy breathing
    • A dry mouth and consequently bad breath
    • At times the tongue pushes constantly against the front teeth causing them to grow forward (buck teeth)

    These changes are not anyone’s fault, as they often start because of blocked noses, allergies, enlarged adenoids, low facial muscle tone or habits formed when a child was younger. But understanding the pattern helps us know how to support change.

    🗣 How mouth breathing affects speech

    Speech depends on precise coordination between the lips, tongue, and jaw. The resting position of these structures affects how ready they are to move.

    1. Reduced tongue strength and placement, i.e. the tongue rests low in the mouth (as it does in mouth breathing), it’s harder for children to lift it efficiently for sounds like /T/, /D/, /N/, /L/, and /S/. This can lead to speech that sounds slightly slushy or unclear, or a frontal lisp.
    2. Open mouth posture and resonance: An open mouth at rest may affect how air vibrates in the oral and nasal cavities. Children might have speech that sounds a bit ‘muffled’ or lacks crispness because the lips and jaw aren’t fully supporting articulation.
    3. Fatigue and breath control: Mouth breathing can lead to drier mouths and less efficient breath support. That can make longer sentences or conversations feel tiring, especially in noisy environments.

    🥄 How mouth breathing affects feeding and chewing

    Feeding involves the same structures that control speech, so posture and breathing patterns matter here, too.

    1. Chewing efficiency: Children who habitually keep their mouths open often have low tongue tone and reduced jaw stability. They may prefer softer foods, chew slowly, or struggle with mixed textures.
    2. Swallowing pattern: A tongue that rests low may push forward when swallowing. This ‘tongue-thrust swallow’ can interfere with efficient chewing and even affect dental alignment over time.
    3. Breathing while eating: Since it’s hard to chew, swallow, and breathe through the mouth simultaneously, children who can’t comfortably nasal breathe may rush bites or pause to catch their breath. This can contribute to coughing, choking, or food refusal.

    Common signs to watch for

    Parents often notice subtle clues before realising mouth breathing is a pattern. Some red flags include:

    • Lips habitually open at rest
    • Drooling after the toddler years
    • Snoring or noisy breathing during sleep
    • Preference for soft foods or grazing eating habits
    • Dark circles under the eyes due to allergies
    • Frequent colds, congestion, or mouth odour
    • Speech that sounds slushy or unclear despite good effort

    If several of these sound familiar, it’s worth mentioning them to your child’s GP, dentist, or speech and language therapist.

    👩‍⚕️ What can help

    1. Address the underlying cause: If nasal blockage, allergies, or enlarged adenoids are making nasal breathing difficult, a medical assessment is the first step. ENT specialists can rule out or treat physical causes.
    2. Encourage closed mouth rest: Gentle reminders like ‘Lips together, tongue up, breathe through your nose’ can help older children become aware of their resting posture. For younger ones, visual cues (stickers or mirrors) can make it a game.
    3. Build oral-motor strength and awareness: Speech therapists can design activities to strengthen the tongue and lips, improve jaw stability, and encourage balanced breathing. This might include blowing games, tongue-tip lifts, use of dental-palatal devices or oral-motor exercises disguised as play.
    4. Support good posture: Sometimes mouth breathing goes hand-in-hand with forward-head posture. Encouraging upright sitting during meals and screen time helps keep the airway open and supports better breathing habits.
    5. Make nasal breathing part of daily routines: Gentle nose-breathing practice during calm times (reading, bedtime, car rides) helps normalise it. Avoid making it a battle: calm, consistent reminders work best.

    🌱 A gentle note on change

    Patterns of mouth breathing develop over time, and change doesn’t happen overnight. It’s important to approach this with curiosity, not criticism. The aim isn’t ‘perfect breathing,’ but to give your child the tools and awareness to breathe comfortably and efficiently.

    Small improvements in nasal breathing and resting posture can lead to big gains in speech clarity, eating confidence, and even sleep quality.

    💡 The takeaway

    Breathing seems automatic, and it is! but how we breathe matters. Mouth breathing and open-mouth posture can quietly shape how a child speaks, eats, and grows.

    By noticing early signs, addressing underlying causes, and building supportive habits, you can help your child move toward stronger, clearer speech and more comfortable mealtimes.

    Just like every area of development, progress starts with connection, patience, and gentle consistency, one calm breath at a time.
