Start on your path today to a stutter-free life and communicate with confidence.

Stuttering is challenging, creating both visible and invisible barriers for those living with it. It’s not just about stumbling over words, but can also the impact on your self-image and your place in the world.

Do you recognise this?

personal struggle

Stuttering often involves a battle fought deep inside. A battle between the desire to speak freely and the fear of the next blockade.

social impact

Those who stutter may feel inhibited in social situations, which can lead to avoiding conversations, activities and even career opportunities.

professional obstacles

Professional interactions require clear communication. Stuttering can complicate these exchanges, limiting professional growth.

emotional impact

The constant stress of speaking can take a toll, resulting in feelings of frustration, embarrassment and sometimes even hopelessness.

practical challenges

Everyday tasks like talking on the phone, ordering at a restaurant or making presentations suddenly become major obstacles.

These challenges are not a snapshot, but a recurring pattern that affects your daily quality of life. This is a problem that calls for an effective and lasting solution.

Who are you?

You are someone who knows all too well the challenge of stuttering. You might use tricks to tell your story. Or do you find stuttering a bit annoying. You may have already walked a path of various stutter therapies. From traditional speech therapy to recognised stutter therapists, looking for a way to get rid of stuttering. You may even have been confronted with the words:

“You have to learn to live with it”.

But that’s not the path you want to stay on. You want more than just methods that offer temporary relief or teach you to accept the stutter.

You know the awkward silences, the missed opportunities in conversations, the suffocating fear of public speaking moments. The social activities you avoided, the important conversations you postponed and the moments you withdrew. They weigh heavily.

But deep down, there is the fervent desire to express yourself as you really are.

Without blocks.

Without fear.

You are ready for change, open to growth and looking for the freedom to say everything you want to say. In every word you speak. Wherever and whenever.

Proven stutter therapy for adults at Del Ferro

What is the Del Ferro Method?

The Del Ferro method is hailed as a pioneering approach for those who stutter. It offers clear vision of a life without stuttering. The method focuses on training the diaphragm muscle, regaining control over it. The result is fluent speaking in any situation. Stutter therapy participants speak without stuttering from the first day of the course.

The technique was developed by Len Del Ferro, an American tenor and vocal pedagogue who made pioneering discoveries in Amsterdam after his international singing career. His main finding was that stuttering is related to uncontrolled movements of the diaphragm muscle.

These insights have fundamentally changed the way stuttering treatment is looked at. The Del Ferro Method was scientifically researched, confirming its effectiveness and the underlying theories of Len Del Ferro.

Since 1992, Ingrid Del Ferro, the daughter of Len Del Ferro, has headed the Del Ferro Institute. She further developed the Del Ferro method into a leading therapy that has already helped thousands of adults (as well as children) around the world overcome their stuttering.

The Del Ferro method proves that stuttering need not be considered an immutable part of a person’s life. By addressing both the physical and mental factors of stuttering, the Del Ferro Institute offers the solution to anyone who longs to speak fluently.

What will you learn during adult stutter therapy?

The stutter therapy consists of two parts. It starts with a 5-day stutter therapy. This is followed by a tailor-made follow-up programme that ensures you keep practising what you have learned until fluent speech has become automatic in every situation.

During the 5-day course, you will learn the Del Ferro speaking technique, which guarantees you complete fluency from the very first day of the course. During the week, technique is perfected, increasing dexterity in fluent speaking.

Not only will you learn to master this technique, but we will hone it together so that you become completely fluent in all speaking situations. Combined with attention to the mental aspects of stuttering, it ensures both that self-confidence increases and speaking anxiety disappears.

You are on the eve of a life where fluent speaking becomes a new reality. You will experience the power and freedom of being able to express your thoughts unhindered. As a result, your self-confidence and belief that a stutter-free life is within reach. Below is an overview of what each course day has in store for you:

Introduction & foundation

On the first day of therapy, you will meet your fellow students, each with their own story, but all equally determined to overcome stuttering. Practising together, motivating and challenging each other strengthens the bond between each other. The highlight of this day is the unforgettable moment when you speak stutter-free for the first time. This moment gives your self-confidence a huge boost and sets the tone for the rest of the therapy.

During this day, you will discover the power of the diaphragmatic breathing technique. You will do this by mastering the Del Ferro breathing exercises, which you will then perform both morning and evening. The workbook will guide you through the process step by step. A nice benefit of this is that the exercises provide relaxation and better sleep. For athletic students, they are also ideal to improve fitness and recover faster after exercise.

Exercise & refinement

The second day is dedicated to reinforcing the skills you learnt on the first day. You will practice the technique in a variety of speaking situations, becoming increasingly familiar with it. Each practice session is carefully designed to refine your speaking skills.

In addition, a unique concentration training is on the schedule. This training is not only important for overcoming stuttering, but also extremely useful for other aspects of your life where attention and focus are essential.

Self-esteem & positivity

On the third day, you will focus on both the mental aspect of stuttering and partially phasing out the technique in preparation for life after completing the course.

You explore how stuttering affects your self-image. You will learn strategies to develop a stronger and more positive self-image. This mental growth is crucial to get rid of stuttering.

Integration into daily life

During day four, you will learn how to speak fluently in everyday life using the Del Ferro method. You will practice with everyday situations that were previously challenging. Think about giving a completely smooth group presentation and speaking without any hiccups during a video recording. It is a day focused on applying what you have learnt. You will embed your new skills into your daily routine.

Closing & outlook

On the last day, you celebrate progress and prepare for a life without stuttering. You show off your new speaking skills by fluently conducting a telephone conversation and reading aloud without stuttering. In conclusion, you will be given a plan to continue growing independently. It is a celebration of what you have achieved and the prospect of a stutter-free future.

If you apply the technique consistently yourself, you will have success guaranteed!

I stuttered for years. As a child, as well as an adult, I attended speech therapy several times. Without success, where I was told: you won’t get rid of it, you have to learn to live with it. I had partly given it a place, but I noticed that I was struggling to convey information properly and I found that very irritating. 

That is why I chose Del Ferro. From day 1, I seized this opportunity. The training and guidance is excellent.
