Meet the MUPPY – a vestibular orthodontic plate

I have become very well versed in Lisp Correction because so many children come to me with this problem! And I absolutely love lisp correction and Articulation Therapy! Please take a look at my blog on tips and tricks for correcting a lisp.

The MUPPY

Over the years I have created my unique style of remediating an Interdental Lisp and as part of my treatment I sometimes use an Orthodontic Tool, called the ‘MUPPY’, which I purchase directly from Germany. I first discovered it some years ago when working with a child with Down Syndrome. Back then I was searching for additional support with my student’s jaw grading and mouth closure difficulties and that’s when I first came across this little tool as recommended by one of my colleagues, a specialist orthodontist in Germany.

I was a bit sceptical at first but I have used it now many times for three years on a variety of clients with varying degrees of lisps. I find it really helps together and in addition to all my other techniques which are language and motor based.

How do I use it?

The MUPPY is a custom-made mouth plate that gently repositions the tongue, encouraging correct tongue placement for clearer speech. It sits comfortably between the lips and teeth; a thin wire sits right behind the teeth, inside the oral cavity.

The plate I like to use for lisp correction has a pearl in the middle. As soon as it is in situ the tongue starts fishing for the pearl and thereby keeps on moving up towards the correct place on the hard palate, just behind the front teeth. This is the place where the tongue tip needs to be for all the alveolar sounds our students find so hard to make.

How does this help reduce a lisp?

A lisp results mainly from incorrect tongue placement during sound production – though at times atypical dentition also contributes to the problem. Specifically, an interdental lisp occurs when the tongue protrudes between the teeth during the production of sounds like /S/ and /Z/. The tongue is often described by parents as ‘thrusting forward’ but I find that is rarely the case. Most often the tongue simply protrudes forward, which is different to tongue thrusting, a more forceful and involuntary movement. Most often I see a habitual tongue protrusion not only for /S/ and /Z/ but also for /T/, /D/, /L/ and /N/. Often /SH/ and ZH/ are also affected.

To visualise this:

  1. A correct /S/ sound looks like this: The tongue tip is raised and touches the alveolar ridge (the bony, slightly uneven ridge behind the upper teeth). The sides of the tongue touch the upper molars.
  2. Interdental lisp: The tongue tip protrudes between the front teeth, creating a /TH/ sound.
  3. Lateral lisp: Here the mechanics of the tongue are different. But using the MUPPY can help here too. To visualise a lateral lisp, the sides of the tongue are not raised high enough, allowing air to escape over the sides. This results in a ‘slushy’ or ‘wet’ sound.

Understanding the specific type of lisp is crucial for targeted therapy and successful correction.

The Vestibular Plate (Muppy) HELPS to guide the tongue towards the right place from where we shape the NEW SOUND.

Methods

Most important to my articulation work re lisping are the motor- and language-based techniques I use, as broadly described below:

  • A thorough oral examination, tongue movements, lip closure, dentition, jaw grading, breath coordination, cheek tonicity, palatal form
  • Discussion on awareness and motivation of child to work on their speech
  • Contrasting sounds at the beginning and end of words: sing vs thing / sink vs think / mess vs mesh etc to raise awareness that it matters what sounds we use in speech and that just one sound can change the meaning of a word completely
  • Mirror work, pulling faces, moving our tongue voluntarily
  • Exploring the oral cavity and thinking about all the parts of the tongue and the palate
  • Finding the alveolar ridge and placing the tongue there at rest
  • Then working towards a good baseline of the other alveolar sounds: /T/ /D/ /L/ /N/ and from there we work towards our NEW /S/ SOUND.

I use a variety of picture clues depending on what is most meaningful for my student:

The child likes a train set, I use the TIRED TRAIN SOUND.

The child knows about bike or car tyres, I use the FLAT TYRE SOUND.

With a student who loves a balloon I might use the FLAT BALLOON SOUND.

And we work our way from correct tongue placement to these long /SSSSSSSSS/ sounds with the help of these visual cues, but also gestural and hand cues such as Jane Passy’s Cued Articulation sound for /S/.

I really love helping children correct their speech sound, be it an articulatory difficulty like the lisp or a phonological difficulty such as ‘fronting’ or ‘gliding’ and I also love working with motor-based speech difficulties we see in Childhood Apraxia of Speech. Feel invited to get in touch if your child needs help in these areas.

Lisp

Help! My child has a lisp. What can we do about it?

ByLondon Speech and Feeding

What is a LISP?

There are different types of LISPS. Let me explain:

A lisp is the difficulty making a clear ‘S’ and ‘Z’. Other sounds can also be affected by the tongue protruding too far forward and touching the upper teeth or the upper lip even. ‘T’ and ‘D’ can be produced with ‘too much tongue at the front’ and this can also have an impact on ‘CH’ and often also ‘SH’.

  1. Interdental lisp

Protruding the tongue between the front teeth while attempting ‘S’ or ‘Z’ is referred to as interdental lisp; it can make the speech sound ‘muffled’ or ‘hissy’. Often, we associate a lisp with the person sounding a bit immature. The good news is that this type of lisp is the easiest to correct and, in my practice. I have a 100% success rate with this type of lisp.

  1. Lateral lisp

In a lateral lisp the person produces the ‘S’ and ‘Z’ sounds with the air escaping over the sides of the tongue. This renders the ‘S’ as sounding ‘slushy’ or ‘wet’. This type of lisp is a bit harder to correct than the interdental lisp. In my experience this can be fixed but it might need a bit longer, more intensive therapy than the interdental lisp.

  1. Palatal lisp

With a palatal lisp the ‘S’ sound is attempted with the tongue touching the palate, much further back than it should be. The ‘S’ sounds ‘windy’ and ‘hissy’. This is a quite rare lisp production but it is also not difficult to correct.

These types of speech difficulties come under the category of ‘speech delay of unknown origin’ and may persist into adolescence and adulthood as ‘residual errors‘.

Some thoughts on Treatment in general:

Lisps can be treated successfully by a Speech and Language Therapist. However, for the treatment to work well, a student needs to be able to cooperate and want to improve his or her speech. Lisp remediation entails a fair amount of repetitive work and very young children or unmotivated older children don’t make the best candidates for treatment for this reason. Often students present with other speech, language or social communication difficulties and here the lisp might not be the priority for treating. For example, it might be that due to a student’s Attention Deficit Disorder they are simply not able to focus on speech practice in their daily life.

When should treatment of lisp begin?

Waiting well past 4½ years is not advisable as the longer we wait and do nothing the stronger engrained the erroneous tongue/speech habit will become. The ‘right’ age for therapy for one child may be different from the ‘right’ age for another child even within the same family. So do make an appointment with a speech and language therapist to assess and see whether your child might be ready to start therapy.

Do lots of children lisp—is it normal?

Until the age of about 4–4.5 years old it can be a perfectly normal developmental phase for some children to have the interdental lisp. But when we see and hear a lateral or palatal lisp we ought to act and see a speech and language therapist for sure.

After the age of 4.5 or 5 years old most speech therapists would agree on at least having a look to see if treatment could be started. The longer we wait the harder it is to retrain the brain pathways to adopt new speech habits.

What happens during the first Speech and Language Consultation?

The first consultation takes about an hour and involves screening relevant areas of communicative function. We take a detailed history, examine the anatomy of the child’s mouth and tongue movements. We check for tongue tie, teeth formation, palate structure and function, as well as swallowing patterns.

Then we begin straight away to try and see if any of the alveolar sounds (T/D/L/N) can be produced correctly with the right tongue placement as that would be the starting point from where to shape a good, clear ‘S’ sound.

The first consultation usually ends with home practice being given, explained to parents and another appointment being made for follow up.

Therapy – what does a session look like?

Each therapy session consists of:

  1. Listening to sounds, discriminating sounds, identifying sounds, listening to rhyming sounds, sound awareness. We call this Auditory discrimination of single sounds: can the student hear the difference between two words that are the same apart from the first sound: ‘sing’ and ‘thing’ or ‘sigh’ and ‘thigh’?
  2. Sound production: using a variety of different prompts and cues we will teach how to physically make the new sound. Often, we work on making a NEW sound, instead of correcting the OLD one. We work on imitation of single sounds then gradually we try and make new sounds in short words, then longer words and then phrases and sentences.
  3. Games! We play games and try and have fun in between listening and producing our new sounds to help students stay motivated and even enjoy the therapy session and process.

How long does it take to ‘fix up’ a lisp?

It tends to take about one term with weekly sessions to help a student make good ‘S’ sounds in phrases and sentences. If the student can do the home practice every day in between the weekly sessions, then in most cases I am able to pronounce the lisp as ‘fixed’ after about one term.

After that the student needs to practise, practise, practise, at home and in daily life to keep reminding themselves of their new skills and their new sound production.

It is a matter of reminding and wanting to get it right. Occasionally a student returns to me for another term of simply practising their skills together with me as they are finding it hard for any number of reasons to practise at home. But generally, 8/10 students will be fine after some 12–13 sessions and their speech will be perceived as perfectly typical by family and friends.
