Principles of motor learning in Childhood Apraxia of Speech (CAS)

ByLondon Speech and Feeding July 5, 2024February 4, 2026

Neurodiversity | Speech and Language Therapy

We use powerful motor learning principles to help children with CAS (Childhood Apraxia of Speech) learn how to produce better, clearer speech sounds in words, phrases and sentences.

What are these principles?

Principle 1: MASSED PRACTICE

This is where you see a child for lots of sessions in a shorter period of time, so for instance six weeks of three times weekly for 30 minutes.

This leads to motor performance or automaticity.

Principle 2. DISTRIBUTED PRACTICE

This is what I use, as most of my clients are not able to come and see me that often on a weekly basis. It is hard to travel in London and life is hectic. So I favour one session a week over say a term or two terms and a session is usually 45 minutes long.

This leads to improved Motor Learning and good generalisation.

During either Massed or Distributed Practice, we choose between 4 variables:

Principle 3: Constant vs Variable

Principle 4: Blocked vs Random

To explain:

Constant Practice is where we repeat the practice of a small handful of target words.

We practise the same target sound in the same word position, e.g. at the beginning of a word: ‘bee’, ‘bye’, ‘bow’, ‘baa’ or ‘key’, ‘car’, ‘cow’, ‘Kaye’ etc.

We keep the rate, pitch and intonation constant.

Variable Practice is where we vary the rate, volume, pitch and intonation of the targets

We use a larger number of sounds, and words that are motivating to say for the child.

For example, if a child loves Peppa Pig then I might choose the words: ‘Peppa’, ‘Daddy Pig’, ‘George’, ‘Mummy Pig’ and a couple of other favourite characters. My child might struggle with a number of sound sequences there but we will target them one by one.

We can also select simpler words like ‘cape’ and ‘cake’ or ‘tick’ and ‘tip’.

Blocked Practice is where we practise one target word for say five minutes then we move to another target word for the next five minutes and then we revert back to the first target word again and so on, so blocks of practice.

Random Practice means we practise several target words at the same time.

How do I decide on what to use?

Good question!

I always opt for distributed practice (weekly for up to 45 minutes).

Within that, I tend to find it most successful to start out with constant practice when a child is finding a certain sound sequence really hard and we need to just ‘nail it’. Bearing in mind I only pick sounds that my student can actually make in isolation, so we are not working on articulation! (where we focus on trying to elicit single sounds correctly – or even at all sometimes) Here in CAS work, we are working with sounds the student can make but is having trouble to add together, into a sequence that is needed to make a word sound right.

As soon as I feel we have some traction I will go to variable practice, i.e. I pick words that are either funny or interesting for the child and it can be a slightly larger number.

I tend to use blocked practice in the beginning or when working on vowels. That’s because it is more important we get our vowels right. They carry a word and are very important for overall speech intelligibility. Once we are on a roll, I tend to go more for random practice.

Example

Here in the video clip, we try and work the /e/ vowel in short words likes ‘bell’, ’fell’, ‘dell’, ‘sell’, ‘smell’ and I am using an AAC device to give a child’s voice as auditory feedback as well as using the PROMPT approach to help my student shape his vowels.

So this is:

Distributed (1 x week for 45 minutes)
Constant – we are practising the /e/ vowel in the same position in six different words
Blocked – we did this: several repetitions of each word and after the sixth we moved to another sound, and then later we came back to this.

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

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.

Can AI help my child’s speech delay? What it can do and what it can’t
ByLondon Speech and Feeding March 11, 2026March 9, 2026
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.

Echolalia · Speech and Language Therapy

What Is Echolalia And Does It Have A Function? How Can Speech Therapy Help With Echolalia?
ByLondon Speech and Feeding January 11, 2022January 31, 2023
Echolalia is a term used when assessing or treating children with Autism. The term refers to the repetition or echoing of utterances, either our own or others’. It can also be echoing phrases heard on television, advertising jingles or catchy repeat phrases used in tv programmes or nursery rhymes and songs. Whilst we all use echolalia occasionally and it can be observed in typically developing children, we tend not to see/hear it beyond the age of 2.5 years old. Children with ASD, however, do use echolalia often into late childhood.

There are generally two types of Echolalia:

Immediate echolalia

Here the repeated phrases or words are produced immediately after someone has spoken the original words or within two conversational turns of the original utterance.

Delayed echolalia

The repeat echoing of the original utterance occurs sometime later, more than two conversational turns or with a much longer time delay. Due to the delay it can be hard to interpret the meaning of the echolalic utterance as it may refer to something that happened long ago and in a different context to the originally utterance.

(Stiegler, 2015, Fay 1967, Blanc 2014)

There are other unconventional speech behaviours which include:
- Perseveration of Speech – persistent repetition of speech
- Repetitive questioning – persisting even though answers were given
- Vocalisations such as: humming, whistling, clicking, squealing etc.
Much research has gone into the meaning and treatment of Echolalia and the following list consists of possible functions that have been identified:
- Information sharing
- Responding to answers
- Labelling
- Drawing attention to self
- Protesting
- Requesting
- Giving instructions
- Self-regulation, calming
(Stiegler 2015, Prizant 1983)

Echolalia does have a function and is part of the Gestalt Learning Process (where longer units of speech are memorised and then used as a whole without the individual words being meaningful).

As a Speech and Language Therapist I promote sound and proven Intervention based on the Hanen Programme which helps provide a highly facilitative Interaction Style and I will tell you a bit more in my next blog how the “More Than Words” approach can help children with echolalia move through their Gestalt Learning into more analytic processing of language, grammar and meaning.

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.

Feeding therapy: A guide for parents and caregivers
ByLondon Speech and Feeding September 6, 2024September 5, 2024
Image by gpointstudio on Freepik

Feeding therapy is a specialised form of therapy and support that helps children develop healthy eating habits and overcome challenges related to food. It’s often used for children with picky eating, feeding disorders, or sensory processing issues.

What is feeding therapy?

Feeding therapy involves a series of techniques designed to improve a child’s eating skills and attitudes towards food. In the UK it’s typically provided by speech and language therapists and dietitians. These professionals work closely with parents and caregivers to create a personalised treatment plan tailored to each child’s unique needs.

How does feeding therapy work?

Feeding therapy sessions are typically 30–60 minutes long and involve a variety of techniques, including:
- Family counselling: Providing support and guidance to parents and caregivers. This can help address any practical, behavioural and emotional issues that may be impacting the child’s eating.
- Play-based activities: Engaging children in fun activities while introducing new foods or textures. This can help alleviate anxiety and make mealtimes more enjoyable.
- Sensory exploration: Helping children become more comfortable with different tastes, smells, and textures. This can be achieved through activities like touching, smelling, and tasting various foods.
- Oral motor exercises: Improving chewing, swallowing, and lip coordination. These exercises can help children develop the necessary skills for eating independently.
- Behavioural techniques: Using positive reinforcement to encourage healthy eating habits. This can involve rewarding children for trying new foods or eating a variety of meals.
When is feeding therapy needed?

Feeding therapy may be beneficial for children who:
- Are picky eaters: Refuse to eat a variety of foods or have strong preferences.
- Have feeding disorders: Experience difficulties with eating, such as swallowing or chewing.
- Have sensory processing issues: Are sensitive to certain textures, smells, or tastes.
- Have medical conditions: Such as autism, cerebral palsy, or gastrointestinal disorders.
Feeding therapy strategies you can try at home

While professional feeding therapy can be invaluable, there are several techniques you can try at home to support your child’s eating development:
- Create a positive mealtime environment: Make mealtimes enjoyable and stress-free by avoiding distractions, limiting screen time, and creating a calm atmosphere.
- Create regular mealtimes and mealtime routines: Introduce set ways of announcing meal times, including songs or short nursery rhymes, try and involve your child with table setting, even just carrying their spoon to the table and putting the beaker next to the plate and ensure that meal time finishes after about 30 minutes, again with a set routine so that the child always knows: this is how we do it in our home, now I am finished and meal time is over.
- Introduce new foods gradually: Start with small amounts and gradually increase exposure. This can help reduce anxiety and make new foods less overwhelming.
- Model healthy eating: Show your child how to enjoy a variety of foods by eating a balanced diet yourself.
- Avoid forcing food: Allow your child to choose and explore foods at their own pace. Forcing them to eat can create negative associations with food.
Seek professional help

If you’re concerned about your child’s eating habits, consult with a feeding therapist. We can provide guidance and support.

Remember, feeding therapy is a collaborative process between parents, caregivers, and professionals. With patience, understanding, and the right strategies, you can help your child develop healthy eating habits and enjoy meals.

Tongue training: Why tongue placement matters for clear speech
ByLondon Speech and Feeding February 12, 2025February 3, 2025
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.

If you have any concerns about your child’s speech, don’t hesitate to reach out to a qualified speech and language therapist, we are here to help! Contact me via my contact form.
