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

ByLondon Speech and Feeding June 17, 2024June 25, 2024

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.

Unlocking language and thinking skills: The power of sequencing
ByLondon Speech and Feeding April 28, 2025April 28, 2025
As speech and language therapists, we often use a variety of techniques to help children develop their communication and cognitive skills. One incredibly valuable tool in our toolkit is the use of sequencing activities. But what exactly is sequencing, and why is it so beneficial?

What is sequencing?

Sequencing, at its core, involves arranging items, events, or actions in a specific order. This could involve putting pictures in the correct order to tell a story, following the steps in a recipe, or understanding the order of daily routines like brushing teeth or getting dressed.

The link between sequencing and language

Sequencing is fundamental to language development and is quintessential to executive functioning skills in several ways:
- Narrative skills: Storytelling, whether oral or written, relies heavily on sequencing. A child needs to understand the order of events (beginning, middle, end) to construct a coherent narrative.
- Explanations and instructions: Providing clear explanations or instructions requires the ability to sequence information logically. For example, explaining how to play a game or how to get from one place to another. In the video clip below we are working on ‘how do make a sandwich’.
- Vocabulary development: Sequencing helps children understand temporal words and phrases like ‘first,’ ‘then,’ ‘next,’ ‘before,’ and ‘after’.
- Sentence structure: Constructing grammatically correct sentences often involves sequencing words in a specific order (e.g., subject-verb-object).
Beyond language, sequencing plays a crucial role in developing executive functioning skills. These are higher-level cognitive skills that help us plan, organise, and manage our time and actions.

Sequencing activities can help children improve in the following areas:
- Planning and organisation: Sequencing tasks require children to think ahead, plan the steps involved, and organise them in a logical order.
- Problem-solving: When they are faced with a problem, sequencing helps children break it down into smaller, more manageable steps.
- Working memory: Holding information in mind and manipulating it, such as remembering the steps in a multi-step direction, is supported by sequencing skills.
- Cognitive flexibility: Being able to adjust to changes in a sequence or think of alternative sequences promotes cognitive flexibility.
Examples of sequencing activities

Here are some practical examples of sequencing activities you can do with your child:
- Picture sequencing: Use a set of picture cards to tell a short story or illustrate a process (e.g., making a sandwich, going to the park). Ask your child to arrange the cards in the correct order.
- Story retelling: After reading a story, have your child retell it, focusing on the order of events.
- Following instructions: Give your child multi-step instructions to follow (e.g., ‘First, get your shoes. Then, put on your coat. Next, go to the door.’).
- Sequencing during play: Integrate sequencing into everyday play. For example, while building with blocks, talk about the steps: ‘First, we put this block here. Next, we add this one…’
- Daily routines: Create visual schedules for daily routines, like getting ready for school or bedtime, to help children understand the sequence of events.
- In the video clip below I am using an on-line language activity which is often fun for children as they can use their finger to swipe the pictures effortlessly into the right place and, if we realise at the end of the story that we have made a little error, we can then easily re-jig the pictures into their correct place.
In conclusion

Sequencing activities offer a powerful way to support children’s language development and enhance their executive functioning skills. By helping children understand and create order, we equip them with essential tools for communicating, learning, and navigating the world around them.

Support your autistic child’s communication by learning the stages of Gestalt Language Processing
ByLondon Speech and Feeding September 28, 2022January 3, 2024

If your child is using echolalia and/or has a diagnosis of autism, then your child’s way of processing language is most likely different to the classic way children typically learn language. We call this process Natural Language Acquisition or Gestalt Language Processing.

Step by Step guide to Gestalt Learning

Let’s explore the following stages of Gestalt Processing:

Stage 1: communicative use of whole language gestalts

(e.g., “let’s get out of here”)

Children and young people in this stage use echolalia. They need to hear more gestalts or scripts. So, your job is to model, model, model and to use functional language that your child can repeat back.

Stage 2: mitigated into chunks and re-combining these chunks

(e.g., “let’s get” + “some more”) and (e.g., “let’s get” + “out of here”)

This is when you take parts of gestalts or phrases and then combine it with other parts.

Stage 3: further mitigation (single words recombining words, formulating two-word phrases)

(e.g., “get…more”)

They are going beyond their gestalts. Furthermore, they may begin to label different objects.

Stage 4: formulating first sentences

(e.g., “let’s get more toys”)

You may see more grammatical errors during this phase as they are creating unique sentences. Please don’t worry about this, it means they are playing and experimenting with language. As communication partners, you could model the correct form of the sentence.

Stages 5 & 6: formulating more complex sentences

(e.g., “how long do you want to play inside for?”)

You can see that language learning is a process, that is trialled and tested, used in different contexts for children to be able to learn and use language appropriately.

My next blog will give you activities ideas and how you might use them specifically with a Gestalt Language Processor.

Remember early intervention is vital. So, if you have any concerns, please seek the advice of a Speech and Language Therapist.

Explore activities for Gestalt Language Processors to aid communication
ByLondon Speech and Feeding September 16, 2022January 3, 2024

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.

Submucous cleft palate: What is it and how does it impact on speech?
ByLondon Speech and Feeding August 26, 2025November 17, 2025
What exactly is a submucous cleft palate?

A submucous cleft palate (SMCP) is much less obvious than its counterparts, cleft of lip and/or palate, and can profoundly impact a child’s speech development. It leads to often extreme hyper nasal speech and difficulty with producing many sounds (/K/ /G/ /T/ /D/ /P/ /B/ /S/ /Z/ /F/ /V/).

In short, the muscles and bone of the soft palate, and sometimes the hard palate, do not fuse completely during foetal development and the mucous membrane that lines the roof of the mouth remains intact, effectively camouflaging the underlying muscular and bony deficit.

So, while the surface of the palate appears normal, the essential muscle and functions responsible for sealing off the nasal cavity from the oral cavity during speech are compromised. This cleft (or lack of muscle) can be seen as a bluish midline discoloration of the soft palate, often a bifid (split) uvula, and at times a notch in the posterior border of the hard palate can be felt upon palpation. However, these signs aren’t always present or easily discernible, contributing to the difficulty arriving at a diagnosis.

Diagnosing a submucous cleft palate is often akin to searching for a needle in a haystack, especially for the untrained eye. Unlike overt clefts that are visually apparent at birth, an SMCP can go undiagnosed for years, sometimes well into childhood or even adolescence. Paediatricians and even ENT surgeons have been known to miss it during routine checks due to the intact mucosal lining. Parents might notice their child’s speech sounds ‘different’ or ‘nasal’ but struggle to pinpoint the cause. Children might undergo extensive speech therapy without a proper diagnosis, as the underlying structural issue continues to hinder progress.

My experience as a speech therapist in private practice:

Over my years of practice, I have encountered several children presenting with persistent hyper-nasal speech and significant difficulties producing plosive and fricative sounds.

It has been incredibly rewarding, though at times challenging, to successfully diagnose SMCP in a number of these children. My approach often involves:
- a meticulous oral motor examination,
- careful listening for the specific qualities of hypernasality,
- and a deep understanding of the physiological requirements for clear speech sound production.
When I suspect an SMCP, I refer these children to Great Ormond Street Hospital where a fantastic multidisciplinary team, typically including ENT surgeons and a specialist speech-language therapist can conduct more definitive assessments. These assessments often involve instrumental analyses such as videofluoroscopy or nasoendoscopy, which provide objective measures of velopharyngeal function and visual confirmation of the anatomical deficit.

The path to resolution: surgery, therapy, and successful outcomes

Surgery

The journey for these children, once diagnosed, often involves surgical intervention. It’s not uncommon for children with SMCP to undergo multiple operations to achieve optimal velopharyngeal closure. These procedures aim to reconstruct or augment the velopharyngeal mechanism, enabling it to effectively separate the oral and nasal cavities during speech. The specific surgical approach depends on the individual child’s anatomy and the severity of the velopharyngeal insufficiency. It’s a testament to the skill of these specialised surgeons that such intricate repairs can be performed with remarkable success.

Speech therapy

Following surgery these children embark on the crucial phase of speech therapy. While surgery addresses the structural problem, speech therapy helps a child learn to utilise their newly improved anatomy. It involves intensive work on developing oral airflow, establishing correct articulatory placement, and reducing learned compensatory strategies that have developed due to the original structural deficit. It is immensely gratifying to witness the transformation. Children who once struggled to produce basic sounds, whose speech was difficult to understand, gradually develop clear speech.

Next steps?

If you’re a parent concerned about your child’s speech and feeding, you’re not alone. The journey can feel confusing, but professional guidance can make all the difference. Never hesitate to have a second opinion when you have that niggling feeling that there is something that has not yet been explored. At London Speech and Feeding I specialise in being thorough and thinking outside the box.

I am here to provide the support you need. Reach out to schedule a consultation and take the first step towards helping your child communicate and thrive.

Empowering non-speaking children: the power of AAC Core Boards
ByLondon Speech and Feeding September 25, 2023September 25, 2023

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

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

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

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

Let’s discover and understand AAC Core Boards

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

Credit: Saltillo Word Power

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

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

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

Building literacy skills

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

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

Customisation for individual needs

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

Collaboration between AAC Core Boards and Speech Therapy

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

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

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

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

For answers to your questions and to explore the most effective support for your child, feel free to contact us.

Conquering the ‘slushy’ /S/: Your guide to treating lateral lisps
ByLondon Speech and Feeding August 13, 2025November 27, 2025
As a speech therapist, few things are as rewarding as helping a child find their clear, confident voice. Among the various speech sound disorders, the ‘lateral lisp’ – often described as a ‘slushy’ or ‘wet’ /S/ sound – presents a unique challenge. While it can be tricky to treat, I’m thrilled to share that I’ve had significant success in helping children overcome this particular hurdle.

What is a lateral lisp?

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

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

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

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

Why is it tricky to treat?

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

I’ve found great success in treating lateral lisps, particularly with children aged six years and older. Why this age group? By this age, children typically have:
- Increased awareness: They are more aware of their speech and often more motivated to make changes. They can better perceive the difference between their ‘slushy’ /S/ and a clear one.
- Improved cognitive skills: They can understand and follow more complex instructions and strategies.
- Better self-monitoring: Their ability to listen to themselves and correct their own speech improves significantly.
- Enhanced oral motor control: Their fine motor skills, including those of the tongue, are more developed, allowing for greater precision.
My approach focuses on a combination of auditory discrimination, tactile cues, and targeted myofunctional exercises to help children ‘feel’ the correct airflow and tongue placement. We use a variety of engaging activities to make the process fun and effective.

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

The recipe for success: Little and often

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

My recommended formula is ‘little and often’. This means:
- Short, focused sessions: Aim for 5-10 minutes of practice, 2-3 times a day. This prevents fatigue and keeps the child engaged.
- Integrate into daily routines: Practise while waiting for dinner, during a car ride, or before bedtime. Make it a natural part of their day.
- Positive reinforcement: Celebrate every small success! Encouragement goes a long way in building confidence and motivation.
- Parental involvement: Parents play a vital role in providing consistent cues and encouragement at home. I equip families with clear, easy-to-follow strategies.
Overcoming a lateral lisp requires dedication, but with the right guidance and consistent practice, a clear, confident /S/ sound is achievable. If your child is struggling with a ‘slushy’ /S/, please don’t hesitate to reach out. Together, we can achieve success!
