Empty Set and Phonology approaches

ByLondon Speech and Feeding

I have been avoiding the use of the Empty Set approach for the longest time as I was not sure if it would work seeing that I am challenging two sounds my student struggles with at the same time. But I decided to give it a go and it works a treat!

With this approach, we use two sounds that our student is struggling with. For example, in my video this student cannot produce /sh/ and /r/. Both sounds have different rules, so I decided to contrast them with each other.

  • The rules of /sh/ are: no voice, air is pushed out through teeth, produced at the front.
  • The rules for /r/ are: use your voice, produce the sound in the middle of the mouth by shaping your tongue in a particular way.

So I chose the words ‘shoes’ and ‘ruse’ as their rules are quite different. Contrasting two sounds the student does not know has been shown to lead to greater change in the child’s articulation. And I can certainly vouch for this as my student is making the best progress with this approach.

Phonology Therapy – what is it, why and how?

Phonology is the study of the sound system of a language. It’s distinct from articulation therapy which focuses on the physical production of sounds.

Phonology therapy focuses on rules. For example, sounds that are produced at the front of the mouth, in contrast to sounds that are produced at the back of the mouth, or sounds that are produced with a long air stream: /s/ or /f/ versus short sounds like /p/ or /t/; sounds are produced with voice or without voice.

Many children, and sometimes adults, are unaware of some of the speech rules and confuse and replace individual sounds. They might say TAT instead of CAT or SIP instead of SHIP.

A quick overview of phonology approaches I use:

Minimal Pairs:

This approach is good for single sound substitutions. We offer word pairs that differ by only one sound, like ‘ship’ and ‘sip.’ One of our first goal in therapy is to highlight the difference between the target sound (e.g., /sh/) and the sound the child uses (e.g., /s/). This helps discriminate and eventually produce the correct sound.

Multiple Oppositions:

A child might replace lots of sounds with a single sound like a /d/. So instead of ‘four’, ‘chore’ and ‘store’ our child says ‘door’, making speech very unintelligible.

The approach is typically geared towards shaking up the phonological system. Our goal is to choose two to four targets that are different from each other, and different from the substituted sound. If our child’s favourite sound is /d/ they can use their voice and make a short sound by stopping their airflow. So I will choose a different target sound to change up the speech system. For example I might choose an /f/, a /m/ and a /k/ sound. So I would contrast: ‘door’ with ‘four’, ‘more’ and ‘core’.

Maximal Oppositions:

In the Maximal Oppositions approach the treatment sets consists of words that are minimally contrasted and that have maximal or near maximal feature differences between each word pair. One word in a pair represents a sound the child ‘knows’ (can say at word level) and the other represents a sound the child does not know (cannot say).

For example, a child may ‘know’ /m/ and be able to say words like ‘man’, ‘mat’ and ‘mine’. However, the same child may be unable to say /f/ as in ‘fan’, ‘fat’ and ‘fine’. The consonants /f/ and /m/ are maximally opposed as follows.

I am always delighted to work on speech sound disorders, I love the challenge and the successes we can celebrate together. Get in touch with me!

    Discover speech and language regression in autistic children and how you can support your child

    ByLondon Speech and Feeding
    Discover speech and language regression in autistic children and how you can support your child

    There’s often this idea that autistic children have extensive vocabulary and knowledge, but this is not always the case. In fact, 30% of autistic children have language regression.

    Goldberg (2003) suggested that speech and language regression refers to the decline in a young child’s speech and communication abilities. We know that regression in speech, language and communication skills often occur before the age of two years. 25% of autistic children develop language at word level between 12 and 18 months of age before losing this language they have learned. As you’re probably aware this regression in communication is a diagnostic indicator of Autism.

    We understand that you want your child to progress, and you struggle to watch as their frustration grows as you feel helpless. I want to provide you with tips so that you can feel empowered to support your autistic child and reduce the impact their communication skills have on the family.

    1. Reduce frustration by providing visuals to support their communication
    2. Model gestalts. We know that autistic children are often gestalt language processors. Learn more about gestalt language processors in one of my previous posts.
    3. Praise the ability to communicate. Focus on what they say not how they say it. E.g., good listening, nice talking.
    4. Provide your child with choices (using real objects to represent your choices). E.g., do you want an apple or banana?
    5. Your child must be motivated and have a purpose to communicate. So, ensure you use highly motivating objects for conversations
    6. Provide them with opportunities to communicate. We need to teach children that if they want something, there’s a process that you need to have the opportunity to ask for it. We find that if parents understand what their child wants (without them asking), the object is given to them, and so there’s no reason for your child to ask.
    7. There’s this idea that we need to teach children eye contact. This is not always the case. Your child is unique, we do not want to take their unique skills away.
    8. Model words which are concrete. E.g., words such as ‘finished’, ‘more’. You can model these several times within the day. You can use a gesture to make the word more visual (see the images below). We know that autistic children are often visual learners.
    Makaton fro "more"
    Makaton for “more”
    Makaton for "finished"
    Makaton for “finished”

    Remember that if your child has speech, language and communication regression, it doesn’t mean your child will stay static.

    It’s vital that you seek support from a qualified Speech and Language Therapist. We can tell you at what point in the communication development that your child is at. And we can support you through the process. We can provide you with an individualised plan specifically for your child to ensure you maximise their potential.

    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.

    What Is Echolalia And Does It Have A Function? How Can Speech Therapy Help With Echolalia?

    ByLondon Speech and Feeding
    What Is Echolalia And Does It Have A Function? How Can Speech Therapy Help With Echolalia?

    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.

  • When ‘star’ sounds like ‘dar’: Understanding speech sound disorders and the path to clearer speech

    ByLondon Speech and Feeding

    If your child says ‘dar’ instead of ‘star’, you might be wondering if they will simply outgrow it or if they require specialised support. While ‘cluster reduction’—dropping one of the sounds in a blend—is a normal part of learning to talk, we typically expect these sounds to lock into place by age four years. If these errors persist as a child approaches school age, it often signals a speech sound delay that may now no longer pass without help. As a Speech and Language Therapist, I specialise in helping children bridge this gap using evidence-based techniques like backward chaining.

    This isn’t about constant correction; it’s about providing the right clinical scaffolding to move a child from ‘frustrated’ to ‘fluent’ before they hit those critical early school years.

    Dropping sounds from words is a common feature of speech sound difficulties, and while it can look small on the surface, it can have a big impact on how clearly a child is understood. In this short video clip, I’m working with a child on an /ST/ sound cluster, demonstrating how I use an evidence-based speech therapy technique called backward chaining to help children build clearer speech with confidence.

    What’s actually happening when a child drops the ‘S’?

    Clusters like /ST/, /SP/, and /SK/ are tricky. They require:

    • precise timing
    • careful airflow
    • and the ability to blend sounds smoothly

    For many children, especially those with speech sound difficulties, this is a big ask.

    So instead of hearing:

    ‘star’

    we might hear:

    ‘tar’ or ‘dar’

    This isn’t laziness or refusal. It’s the child simplifying the word to make it manageable.

    Why I don’t start by saying ‘say star’

    Telling a child to ‘just add the S’ rarely works.

    Instead, I meet them where they are already successful.

    In this clip, the child can already say ‘dar’ clearly. That’s our starting point.

    Backward chaining: building speech from success

    Backward chaining means we:

    1. Start with the part of the word the child can already say
    2. Gradually add the missing sound
    3. Keep the child feeling successful at every step

    So rather than jumping straight to ‘star’, we:

    • secure the ending
    • gently introduce the /S/
    • and blend it in a way that feels achievable

    This approach reduces frustration, builds confidence, and helps the sound stick not just in the therapy room, but out in the real world.

    Why this matters beyond one word

    This isn’t just about saying ‘star’.

    It’s about:

    • teaching the mouth a new movement pattern
    • giving the brain time to organise the sound sequence
    • and helping the child feel capable, not corrected

    When therapy feels safe and successful, children are far more likely to generalise their new sounds into everyday speech.

    Speech therapy works best when children feel supported not tested.

    If your child struggles with speech clarity

    If your child:

    • drops sounds from words
    • avoids longer or trickier words
    • or becomes frustrated when they’re not understood

    This is the kind of work I do every day building speech step by step, in a way that respects each child’s pace and strengths.

    Support can be gentle, effective, and empowering.

    Understanding Angelman Syndrome: A guide for parents

    ByLondon Speech and Feeding

    Angelman Syndrome (AS) is a complex neurological disorder that affects development. It’s caused by a missing or functionally incorrect gene (UBE3A) on chromosome 15. While AS is rare, understanding its characteristics is crucial for parents and caregivers.

    What are the key characteristics of Angelman Syndrome?

    Children with AS typically exhibit a range of unique characteristics, which can include:

    • Developmental delay: Significant delays in reaching developmental milestones, such as sitting, crawling, and walking.
    • Speech impairment: Limited or absent speech. Individuals with AS may use few or no words.
    • Movement and balance issues: Difficulties with coordination, balance, and movement, sometimes causing a jerky or unsteady gait.
    • Happy demeanour: Frequent smiling, laughter, and a generally happy, excitable personality.
    • Intellectual disability: Varying degrees of intellectual disability.
    • Seizures: Seizures are common and often begin in early childhood.
    • Sleep difficulties: Disrupted sleep patterns and difficulty falling asleep.

    The role of Speech and Language Therapy

    Speech development and social communication is significantly affected in Angelman Syndrome, and therefore, Speech and Language Therapy plays a vital role in helping individuals with AS to communicate. As Speech and Language Therapists (SLT) we can work with the child and family support any of the following:

    • Assess communication skills: We evaluate the child’s current communication abilities, including any vocalisations, gestures, or signs they may use. With younger children we do this through play and playful social games as well as observation of a child playing and interacting with their siblings or caregivers.
    • Develop alternative communication strategies: Since spoken language may be limited, SLTs can help the child learn other ways to communicate, such as nonverbal communication, e.g
      • Gestures: use of pointing, waving and miming certain activities.
      • More formal sign language: Teaching basic signs to express needs and wants.
      • Core boards: Using pictures and symbols to represent everyday common words, actions, and feelings.
      • Augmentative and Alternative Communication (AAC) devices: Providing electronic devices that can produce speech.
    • Encourage vocalisations: When words don’t readily develop, SLTs can encourage the child to make vocalisations and sounds, as these can be a form of communication.
    • Support language development: SLTs can work on understanding of language, even if expressive language is limited.
    • Educate and support families: SLTs provide families with strategies and techniques to support their child’s communication at home.

    The importance of a multidisciplinary approach

    Caring for a child with Angelman Syndrome requires a team effort. A multidisciplinary approach, involving various healthcare professionals, is essential to address the diverse needs of the individual. This team may include:

    • Paediatrician: Provides overall medical care and monitors the child’s health.
    • Physiotherapist: Helps with movement, balance, and coordination.
    • Occupational therapist: Works on daily living skills, such as feeding, dressing, and self-care.
    • Speech and Language Therapist: Addresses communication and language needs.

    By working together, we can provide comprehensive care, address the unique challenges of Angelman Syndrome, and help the child reach their full potential.

    Conclusion

    Angelman Syndrome presents unique challenges and opportunities. With early diagnosis, appropriate interventions, and a strong multidisciplinary team, children with AS can make good progress and live fulfilling, joyful lives. As Speech Therapists we delight in supporting parents in their role in advocating for their child.

    Milestones of autistic children: Crawling, walking, and talking

    ByLondon Speech and Feeding
    Image by wayhomestudio on Freepik

    For all children every milestone achieved is a testament to the unique and intricate process unfolding within each young mind. For autistic children, this journey may present a distinct pattern, with some reaching developmental milestones like crawling, walking, and talking later than their neurotypical peers. Let’s have a look into the fascinating realm of Autism and explore why some autistic children might crawl, walk, and talk later, shedding light on the underlying factors contributing to this unique way of developing.

    1. Individual Pacing:

    Child development is not a one-size-fits-all journey. Each child, whether neurotypical or autistic, has a unique timeline for achieving milestones. Autistic children, like any other children, follow their own pacing. This individual rhythm might lead them to focus on one set of skills before they progress to others. Like some neurotypical children might focus on talking earlier than walking, autistic children might prioritise other areas before crawling or talking.

    2. Neurodevelopmental Complexity:

    The human brain is a remarkable entity, with a bewildering array of interconnected processes that lead to us achieving our developmental milestones. Autistic children often have variations in “neural wiring”, which can impact the balance between gross motor skills (crawling, walking) and fine motor skills. Speech and language acquisition falls under fine motor skills and may be momentarily disrupted due to the divergent neurological pathways at play in autism.

    2. Sensory Processing Differences:

    One of the hallmarks of autism is altered sensory processing. Autistic children often experience sensory stimuli differently than their neurotypical peers. This heightened or diminished sensitivity can influence a child’s desire or ability to engage in activities like crawling and walking. The sensation of movement while crawling or walking, for instance, might be overwhelming for some autistic children, causing them to either avoid or delay these activities.

    3. Visual-Spatial Abilities:

    Autistic children and adults frequently display excellent visual-spatial abilities. This strength might lead some children to focus more on activities that engage these skills, potentially delaying their engagement with activities like walking or talking. As they navigate their environment and process information visually, they might naturally invest more time in activities that stimulate this particular cognitive ability and strength.

    4. Communication Challenges:

    For many autistic children, speaking can be a really complex and difficult endeavour. Communication delays are a common feature of autism. This can affect both receptive and expressive language development. While some children might be physically capable of crawling or walking, they may not yet have the tools to communicate their desires and intentions. This leads to a temporary focus on non-speaking forms of expression. This does not mean that they do not communicate at all. But autistic individuals often start out using jargoning or echolalia as a form of communication as well as behaviours and physical forms of communication.

    5. Executive Functioning and Motor Skills:

    Executive functioning, or abilities for planning, organising, and carrying out tasks, can vary in autistic children. These skills are crucial for activities like crawling, walking, and talking, which need coordination and planning. About 40% of autistic persons have a motor planning difficulty.

    6. Intense Interests and Routines:

    Autistic children often develop intense interests in specific subjects, sometimes to the exclusion of other activities. These interests might become their primary mode of engagement. They might side-line milestones like crawling, walking, or talking. The mostly rigid adherence to routines and preferences might cause them to allocate more time to their preferred activities. This delays their engagement with other developmental tasks.

    How can Speech and Language Therapy help:

    Support and Intervention:

    Early intervention and regular Speech and Language Therapy play a pivotal role in the developmental journey of autistic children. Therapies tailored to individual needs can aid in bridging the gaps between milestones. Occupational therapy, for example, can help address sensory sensitivities and motor skill challenges that might impact crawling and walking. Speech therapy can help communication development, gradually bridging the gap between non-verbal expressions and spoken language.

    For example, we now know that echolalia or jargoning of longer phrases with intonation, repeating scripts from favourite tv shows or songs have many meanings and communicative functions. For example, a child who utters long strings of echolalic utterances, often difficult to understand, might want to do any one of the following:

    • Comment
    • greet
    • ask a question
    • make a request
    • express surprise
    • negate something.

    We now understand that the way to support a child with echolalia is to acknowledge all utterances and try and find out what the meaning is behind these scripts. This is very supportive. Over time it will lead a child to move on to understanding and saying more clear and self-generated language. For more information about this Natural Language Acquisition here are some other great websites for you to look at:

    Conclusion

    In conclusion, the journey of an autistic child’s development is a testament to the uniqueness and complexity of the human mind. The delays or differences in achieving milestones like crawling, walking, and talking can be attributed to a range of factors, including

    • neurodevelopmental intricacies,
    • sensory processing variations,
    • and communication challenges.

    It’s crucial to recognise that these delays are not indicative of a lack of potential, but rather a manifestation of the intricate interplay between an autistic child’s strengths and challenges. By embracing these differences and providing tailored support, we can help each autistic child unfold their potential at their own pace.
