About stammering

Stammering is a struggle to get words out. Typical features of stammering include repetition of sounds / words, prolonging initial sounds / words or not being able to produce any sound. Stammering is often accompanied by physical tension in the face and body.

Stammering is a variable and unpredictable condition. People who stammer can often experience periods of fluent speech but may also struggle to speak at other times.

People who stammer may avoid words or situations they feel will increase their likelihood of stammering. In some people who stammer, they may avoid things to such an extent that their stammer will be completely hidden. This is known as "interiorised" or "covert" stammering.

Stammering is often compared to an iceberg: there is a lot going on underneath the surface which others do not see. The visible part of the stammer includes repetition of sounds/words, prolonging initial sounds, and being unable to produce sounds. Under the surface part of the stammer includes avoidance, negative thoughts, and feelings such as frustration, embarrassment and shame. These hidden features have a role in maintaining the stammer. Both visible and hidden features are addressed in therapy.   

How to access our services

If you are an adult who stammers and would like to see a Speech and Language Therapist who specialises in working with stammering, you can either self-refer or request referral via your GP.

For self-referral, please contact us by telephone: 01388 455 200 or email: cdda-tr.staffcentraladmin@nhs.net

We understand that using the telephone can be daunting if you are a person who stammers. You may wish to read the following information before you call us so you know what to expect.

  • When you call, you should select "option 3" for "any other service".
  • You will be asked for your name, DOB and/or NHS number (don't worry if you don't know this).
  • You will be asked to confirm your address and telephone number.
  • You will be asked if you have a religion, what your ethnicity is and what your main spoken language is.
  • You will also be asked if you want to share your records with other clinical services.
  • Once the phone conversation is over, a member of the admin team will create a referral and a therapist will look at this then place you on a waiting list for therapy.

You will be invited to an initial appointment via letter.

If you would like to refer by email please begin your email with: 'I would like to refer myself to the Adult Speech and Language Therapy service for therapy for my stammer.' Then, include the following information: 

  • Name
  • Date of birth
  • NHS No: (if known)
  • Address
  • Contact telephone number
  • GP name and address

What causes stammering?

Stammering is not caused by one single factor. For each person, there are a number of factors which contribute to their vulnerability to stammering and to whether their stammer is likely to continue. In young people and adults, there are 5 main areas which may contribute to stammering. These are:

  • Neurophysiology - in some adults who stammer, there are differences in the way their brains are structured or how they work, compared to adults who do not stammer.
  • Pharmacological - stammering can occur as a side-effect of medication or recreational drug use.
  • Psychogenic - stammering may arise from a psychological response to stress or trauma.
  • Re-occurrence of a childhood stammer - a childhood stammer may re-emerge when coping strategies are no longer working for that person.
  • Idiopathic - any contributing reasons to the stammer are not known.

In children, young people and adults, there are also some factors which may contribute to the occurrence of stammering. These are:

  • Linguistic factors - stammering is more common at the beginning of sentences, and in sentences with long and complex structures.
  • Sex - stammering occurs more frequently in males.
  • Environmental factors - events or things in the environment can acts as stressors which may coincide with the start of stammering, or stammering becoming more severe.

What to expect from stammering therapy

The initial appointment will be informal. The Speech and Language Therapist will take a case history which will include information such as how long you have been stammering and what impact stammering has on your life. They will also ask what your hopes are for therapy, as well as providing you with realistic expectations of therapy, and more information about stammering and the support available. The therapist will work with you to set some preliminary goals for therapy and to obtain some pre-therapy outcome measures.

You will not be asked to read aloud or be formally assessed. Please feel free to bring a friend or family member with you if you wish.

We have three Highly Specialist Speech and Language Therapists who specialise in stammering.

There are different therapies available, and the therapist may use multiple techniques in sessions with you.  The therapies available include stammering more fluently, speaking more fluently, behavioural approaches, psychological flexibility approaches and much more. 

Stammer more fluently

These techniques aim to modify your stammer so that you stammer more easily and less struggle. 

Variation: Non-Speech and Speech Experiments  

The aim of variation is to enable the person who stammers to explore and experiment with choice and the possibility of change.  Many people may feel that they have no choice in how they communicate or how they stammer but this is not the case.  We begin experiments with change with tasks that are unthreatening but that help the person who stammers to see that they do have choices in how they may think, feel and behave.  This process is referred to as 'loosening'.

Examples of variation of non-speech might include smiling more, maintaining eye contact when people talk to you or pausing before you answer a question.

Speech variation might include: Speaking slower or faster than usual in one conversation and noticing how that feels or speaking with a softer voice.

An example of varying stammering behaviour might involve shortening a prolongation, reducing 'fillers' such as 'ums' and 'ers' or talking to a new person at a bus stop.

Variation experiments are a useful introduction to desensitisation.

Identification

Therapy often begins with a process of understanding the various components of stammering.  We introduce the concepts of overt (observable) and convert (hidden) stammering using the iceberg metaphor.

From there it is possible to specifically identify overt features in more detail, e.g. When do you block? Where do you notice during prolongations? What are you doing with your hands when you block?

It is helpful to be able to explore and understand these core and secondary behaviours in depth but can be challenging.  It may be the first time person has really examined their stammer and this provides a good foundation for the desensitisation work that follows later.

This image of the stammering 'onion' revealing the layers of core and secondary stammering behaviours is useful.  Click here

Following on from identification of overt systems, time is devoted to exploring the underlying features that serve to maintain stammering.  These can have far reaching consequences and cover a wide range of symptoms including: avoidances, emotional responses to stammering: beliefs about self, such as low confidence and low self-esteem and ways of thinking.

Therapists will introduce various tools and approaches to enable detailed understanding of these complex features.

Desensitisation techniques

Desensitisation allows you to develop a different relationship with your stammer.  If you have been stammering most of your life you may have developed strategies to avoid stammering in order to not experience difficult feelings of embarrassment and shame.

To desensitise you need to begin to allow yourself to stammer while developing ways to feel calmer and less reactive.  This is a process of toughening up and it can be a challenging but important part of therapy.  Through allowing yourself to experience discomfort in a graded way you begin to learn a lot more about you and your stammer and often find that you can manage the stammer differently.

Some examples of desensitisation include voluntary stammering (stammering on purpose), learning to tolerate pauses, making eye contact, speaking in situations that you might normally avoid.  Your therapist will guide and support you through this.  It is a process that often continues long after therapy ends.

Voluntary stammering - this is one tool to help with desensitation

Voluntary stammering is stammering on purpose.  It is useful for people who stammer because:

It encourages people to approach stammering, not run away from it.

It allows a person who stammers to let other people know that they stammer.

It is giving the person who stammers control of when and how they stammer, and how they feel about stammering.

Tolerating stammering - this is another desensitisation tool

This is a technique to help you to be more comfortable with stammering openly.

Block modification

Block modification is a technique which is not aimed at helping the person to become fluent but at helping the person to stammer more fluently. It teaches the person to change or modify their excess tension involved in stammering into a way of stammering in a more controlled and easy fashion.

 The following are block modification tools:

Cancellation

When a person stammers they are often rewarded with a few words of fluency if they struggle through the block. Therefore the person with a stammer will learn to push through their blocks in the hope of achieving those brief moments of fluency. Pushing through blocks creates excessive tension which in turn makes the stammer worse.

Post-block modification is a way to come out of that struggle by stopping the push-through with the blocks and replacing those blocks with pausing, after which the stammered word is attempted again but this time with more control. For example:

  • The stammered word can be finished in any way that the person can
  • After the word is spoken, a pause of about 3 seconds is used
  • The person with a stammer will then use the pause to calm down, getting rid of all the tension associated with the stammer
  • Whilst in the pause, the stammered word is reproduced silently (this is referred to as the "pantomimed word")
  • The pantomimed word is practiced silently in a calm, fluent manner
  • After the pantomime, the stammered word is then said but with less struggle

Pre-block

This is anticipating the stammer and modifying the struggle and tension of the stammered word before the word is actually spoken. It is important to pause before the word on which stammering is anticipated. Before the stammered word is spoken all the speech muscles will relax. The person will then think about how to say the word in a relaxed easy manner. Finally the word is spoken in a more controlled manner.

In-block

This is modifying the stammered word during the stammer itself. Once the stammering begins on the affected word, it is important to stop struggling. In that moment of stopping, the stammered word can be modified by either slowing down the block plus releasing all the tension around it, or by slowing down all repetitions. The result would be a modified stammer which is slow and spoken in a relaxed manner.

Rate control

Many people who stammer say they feel under pressure to speak quickly and feel a sense of urgency to get their words out before they stammer. The majority of people who stammer find that slowing their speech rate does increase their fluency. In therapy working with a more relaxed, flexible rate can be helpful, using pauses to allow for breath support and more relaxed articulators.

Pausing

This is to introduce gaps in speech. Gaps in speech are often perceived as spaces in conversation which will allow the person with a stammer to stammer even more. As a result, the person feels compelled to speed up their speech to fill in the gaps in order to reduce the likelihood of even more stammering. Consequently the stammered word becomes more tensed and the blocks are worsened.

Pausing allows time to think, time to be a good listener, time to emphasise words or emotions and allows time for speech control to occur. Pausing is taught in a series of hierarchical steps - initially introducing pausing in two word phrases, moving on to four word phrases, then introducing increasingly more frequent pausing in longer and longer sentences.

Pausing is a valuable speech strategy; people who stammer experience problems because they find it unnatural, as they are used to a fast rate of speech. It will take time to practice pausing and to incorporate it into everyday speech but the rewards are worthwhile as it can result in less struggling with speech. 

Speak more fluently 

These techniques aim to increase the fluency of your speech. 

Easy onset

Easy onset is a fluency tool which helps coordinate breathing and speech.  It combines breathing out with a gradual onset of voicing, light contact of the articulators and slightly the initial sounds.  It is easier to use following therapy on breathing, relaxation and practice of forming light contacts.

Rate Controls (you may also hear this referred to Slowed / Smooth speech)

Many people who stammer say they feel under pressure to speak quickly and feel a sense of urgency to get their words out before they stammer.  The majority of people who stammer find that slowing their speech rate does increase their fluency.  In therapy working with a more relaxed flexible rate can be helpful, using pauses to allow for breath support and more relaxed articulators.

Rate control and pausing need to be combined with desensitisation and avoidance reduction and it can be taught alongside easy onset and breath support.

Breathing

Attention to breathing has long been associated with stammering therapy.  Many people who stammer report tightness and tension in the chest and throat and often feel that they hold their breath during tense blocks.

Breathing is a dynamic process so it changes all the time depending on what we are doing or how we are feeling.  For this reason it is not possible to fully control our breathing all of the time.

In therapy, time is spent complaining the mechanics of breathing and learning how to breathe from the diaphragm.  This is useful for increasing capacity and control of the breath and also for relaxation purposes.

From there vocal exercises can be introduced which help with coordination of airflow and voicing in a smooth, relaxed way.

Behavioural approaches

These techniques aim to help you change unhelpful ways to coping with your stammer and experiment with new ways such as reducing avoidances. 

Avoidance Reduction / Exposure Therapy

One theory is that stammering is the result of two opposing urges: the urge to speak (the approach response) and the desire to hold back from speaking (the avoidance response).  Avoidance reduction therapy aims to reduce the avoidance response.

Some examples of avoidance are:

  • Avoiding words - the person who stammers substitutes the word they fear they will stammer on, replacing it with another word which they find easier to say.
  • Avoiding situations - the person who stammers avoids situations they think will be difficult e.g. ordering at a restaurant or using the telephone.
  • Avoiding expressing feelings - the person who stammers avoids expressing feelings such as upset, because they feel expressing emotion is letting their guard down or letting their stammer out.
  • Avoiding relationships - the person who stammers avoids creating and maintaining relationships, through avoidance of activities such as going to the pub or a sports game, avoiding asking or answering questions, and not keeping in contact.
  • Avoid self-role - the person who stammers avoids accepting themselves as a person who stammers.

Avoidance reduction therapy is used when the person who stammers has significant levels of avoidance. They may exhibit some of the behaviours shown above.

People are encouraged to gradually move from their comfort zone to their stretch zone using goals set by them.

Therapy may include activities such as: using avoided words in conversation, developing coping strategies to allow the person to enter into situations they would normally avoid, and role play.

Psychological flexibility approaches

These techniques aim to reduce your negative feelings about stammering, develop more confidence and acceptance of your stammer. 

Acceptance and Commitment Therapy (ACT)

ACT is a behavioural therapy used to work with a whole range of varied conditions such as anxiety, depression and pain.  There is good evidence that it can also be very effective in helping people who stammer (Beilby, Byrnes & Yaruss, 2012).

ACT is named after one of its key messages: acceptance.  It focuses on accepting what is out of your control and committing to living your life fully.

ACT teaches a range of psychological skills which will enable the person who stammers to manage difficult thoughts and feelings they may have about their stammer.  They may have strong beliefs that there are things they cannot do because they stammer.  ACT will help them reappraise this belief.

In therapy, a person who stammers will be introduced to a range of mindfulness skills that will help them to manage challenging emotional states that might arise due to stammering.  ACT will also help them to identify what is really important to them, clarifying their values so that they can take action to move towards their goals.

ACT can be used in conjunction with work on fluency techniques.  We adopt the principle that you try to change what you can but accept what is not possible to control.

This metaphor is a demonstration of how ACT works.

  • A man is walking along wearing his coat. The wind starts blowing furiously, which makes the man grip tightly onto his coat as he struggles against the wind.
  • Later, the wind dies down and the sun comes out, so the man takes off his coat and carries it for the rest of his walk.

The coat represents the man's stammer, the wind represents the energy spent covering up his stammer, and the sun represents acceptance of his stammer. When the man is covering up his stammer, he is using a lot of energy and is struggling, making him unable to enjoy his walk. When the man accepts his stammer, he no longer has to struggle so he can enjoy his walk.

Mindfulness

Mindfulness is a form of self-awareness whereby we pay attention to the present moment without making judgements about what we notice. We spend much of our lives on 'autopilot', not really aware of what we are doing or how we are thinking or feeling. Our minds are busy, often distracted thinking about events from the past or worrying about and planning for future events. This state of mind can be a source of distress and unease. Mindfulness practice enables us to observe our habitual thinking patterns and reactions with less judgement and in time we can learn to allow our experience to be as it is. With mindfulness practice we can develop a particular kind of awareness that is more accepting and more compassionate towards ourselves.

Mindfulness Meditation practice is a key factor in many evidenced-based psychotherapeutic interventions including Acceptance & Commitment Therapy (ACT), Mindfulness Based Cognitive Therapy (MBCT) and Mindfulness Based Stress Reduction (MBSR).

Why practice meditation as part of stammering therapy?

There is good evidence to suggest that mindfulness based approaches can be helpful in promoting increased feelings of calmness and relaxation. We experience these benefits not through 'trying' to relax but paradoxically through learning to allow your experience to be exactly as it is without trying to change anything.

People come to therapy with a desire to change that which is causing them suffering or unhappiness e.g. wanting to be fluent and have control of their stammer.  However, in the pursuit of change and control we can struggle against our experience in unhelpful ways. For example it is natural to want to avoid stammering, to try 'not to do it', but this is more likely to increase tension by placing excessive pressure on a system that is hard wired to stammering.

Mindfulness practice invites us to recognise when we are struggling against our experience and instead practice allowing things to be as they are. This is the beginning of acceptance and often change can flow from this.

As Tom, one of our clients, says in his testimonial 'Stammering itself is peculiar in that the more you fight it, the more effort you put in to trying to control it to your will… the worse it gets.'

​​​​​​Mindful Awareness of Body & Breath

Mindfulness based approaches encourage a kindly curiosity to sensations in the body and awareness of breath. This non-judgemental awareness of the body can help people who stammer to tune in to tension in the body during moments of stammering. With practice it becomes easier to identify habitual negative thought patterns that can manifest in the body as muscle tension. This might affect the breathing and speech muscles. 

For example, having the thought 'I hope I don't stammer' leads to feelings of anticipation and fear, resulting in tense breathing and tense muscles in the body and face which can increase the chances of stammering.

Research has shown that mindfulness based approaches can inhibit the fear response in the brain and enable a calmer, more rational response.

Solution Focused Therapy (SFT)

SFBT is a therapy approach which uses questions to encourage clients to generate their own reflections and thinking and in so doing arrive at their own answers / solutions to the problem. These are questions which are not meant to gain information from the client but to lead the client into generating their own solutions.

SFBT believes in focusing on the moment and the positives that each client brings. Focusing on the past is not helpful. The focus is also not on the therapist providing the answers but in stimulating the client to empower themselves with solutions they are encouraged to discover.

Cognitive Behavioural therapy (CBT)

What is CBT?

Underlying CBT is the principle of negative automatic thoughts. These are the negative beliefs and predictions that people who stammer have established based on previous negative experiences. These experiences may have happened on one occasion in the past but because their negative associations have been so strong, the person who stammers will start to expect the same negative effects if they have to experience the same situation again.

For example, the experience of being rejected for a job because of their stammer may lead the person who stammers to expect to be rejected for every single job because of their speech. A vicious circle of fear/anxiety starts to develop around every job interview, leading to increased tension and fear, causing avoidance of job interviews, which creates frustration. This in turn will lead to more fear and anxiety.

How does CBT work?

Speech and language therapists use CBT in stammering by challenging the person who stammers negative automatic thoughts. They help them to identify and elaborate thought records. These thoughts are challenged by asking the person who stammers to explore the justification / evidence for them. Questions asked of people who stammer can include "are these thoughts real?" and "what is the evidence for them?"

People who stammer are also asked to experiment with different but more positive thoughts e.g. they are asked to reflect on why the person who is talking to them looks away when they stammer. The natural conclusion for people who stammer is that the person is ignoring or mocking them. People who stammer are asked to think about other reasons e.g. perhaps the person is looking away because they feel awkward as they do not know how to react to the stammer. People who stammer are also encouraged to problem solve and to experiment more positive ways of thinking around specific speaking situations.

CBT and other approaches

CBT can be used in conjunction with work on fluency techniques. It can also be used at the same time as discussions around what makes a good communicator and enabling the person who stammers to understand the overt and hidden features of their stammer.

Education and Mind-Body Connection

When we experience a threat, whether real or imagined, the amygdala, a small region in our brain responds by alerting the brain to release the stress hormones cortisol, adrenaline and noradrenaline. This is called the fight or flight response. The brain prepares the body to either fight or run away from the danger.

A typical scenario for a person who stammers may be being in a situation where there is a very real expectation of stammering e.g. waiting their turn to introduce themselves to a new group of people. Whilst waiting their turn, they may experience many of the physical symptoms below: heart pounding, shallow breathing, feeling hot and sweaty, the mind will be racing and they may be feeling emotionally off balance. 

The problem is that mostly we cannot fight or run away in the way our ancestors would have done.  However, people who stammer acknowledge that in order to reduce the distress associated with stammering they will actively avoid situations that cause physical and emotional discomfort, e.g. making an excuse to leave the room before having to introduce themselves.  This has the effect of making them feel safe and relieved in the short term but also leads to high levels of anxiety when the next threatening situation looms.  Over time the brain learns to be anxious in those situations where stammering may be anticipated.   People who stammer may develop a whole range of avoidance strategies in order to understandably feel safe.  These safety seeking behaviours however, may be very life limiting and prevent the person from discovering new ways of managing their fears and ultimately of leading a full life.

We can all experience an amygdala response when our senses become overwhelmed due to a threatening situation. Neurologically the amygdala response has the effect of shutting down the thinking /planning part of the brain, the pre-frontal cortex. This explains why we can't think straight or be rational in those situations. This also explains why it is so difficult to put fluency techniques into practice when you really need them. Despite your best intentions, you may find yourself rushing though a sentence and blocking on key words because you are unable to remain calm.

Mindfulness based approaches have been found to be helpful in reducing anxiety, stress and fear responses in that they help to regulate emotions by calming down the amygdala and strengthening the activity in the pre-frontal cortex.
