But this is where an invisible and painful problem arises. Statistics show that people struggle with traditional speech therapy for an average of seven years before finding their way to the Del Ferro Institute. Seven precious years in a child’s crucial developmental phase, during which fear, feelings of inferiority, and frustration can take deep root.
Within conventional speech therapy for a child who stutters, the focus quickly shifts to acceptance. The child is taught tricks to stutter more fluently or to pronounce words in an extremely prolonged and unnatural way. As director Ingrid Del Ferro recently and powerfully put it on NPO Radio 1:
“Del Ferro is not a method of acceptance; it is a solution method. You are literally and figuratively giving people their voice back.”
The Invisible Exhaustion: Synonyms and the Fear of the Letter 'K'
At school, speech blocks rarely manifest solely as audible stammering. At a young age, children already develop a radar to avoid rejection and bullying. They become masters of invisible, exhausting avoidance behavior.
Even adults who received speech therapy in the past fall back into this. During the broadcast on Radio 1, the host confessed that when he is tired, he still struggles with the letter ‘K’. If a sentence begins with it, he unconsciously rephrases it in his mind.
For a child in primary or secondary school, this is a daily, immense mental burden:
Constantly rephrasing sentences
The child scans every word in advance. Is the initial letter too daunting? Then they quickly search for a synonym, which comes at the expense of spontaneity and energy.
Intentionally giving incorrect answers
A child may well know the correct answer to the teacher’s question, but because the word starts with a difficult sound, they intentionally give a wrong answer that is easier to pronounce.
Being silenced
The fear of introductions or being called on in class causes a child to make themselves completely invisible and perform far below their actual intelligence level. The biggest misconception is that stuttering has anything to do with intelligence.
The Physical Key: Speaking on the Exhalation
Why, then, does weekly speech therapy fail to address these persistent blocks? Because the problem is not in their head and cannot be fixed with simple speech lessons. It is a purely physical faltering of the diaphragm muscle—the muscle that is 90% responsible for our breathing.
The institute’s revolutionary discovery pinpoints the exact problem: a person who stutters unconsciously attempts to speak on an inhalation. As soon as a child feels speaking tension, the diaphragm makes uncontrolled movements. The upward airflow is instantly blocked, the vocal cords snap shut, and the word becomes completely stuck.
During the intensive 5-day training, a child learns to physically manipulate and control this muscle. We teach them to start speaking on the exhalation at the exact right moment. This acts as a mechanical lock: anatomically speaking, the muscle simply cannot move uncontrollably. When the diaphragm moves smoothly, stuttering is physically impossible.
No Tricks, Just Absolute Freedom of Mind
Many parents worry that an intensive training program will teach their child an artificial way of speaking. At Del Ferro, we do the exact opposite: we teach no tricks. The goal is completely free, fluent, and natural speech. Our instructors have firsthand experience: they speak 100% fluently without you noticing a thing.
Furthermore, we do not resolve speech blocks within a clinical, artificial bubble. From day one, children directly face their speech anxieties. Under guidance, they make phone calls, read aloud, give presentations, and order exactly what they want directly in a shop or restaurant. Without escaping into safe synonyms. These immediate successes give their self-confidence a massive boost.
In this way, the institute has also helped elite athletes, such as professional soccer player Lutsharel Geertruida and top athlete Jeff Tesselaar. Despite their athletic success, their stuttering made them afraid to give interviews. Thanks to Del Ferro stuttering therapy, they now communicate with the media with absolute confidence.
Perfectly Easy to Schedule During Any School Holiday
You do not need to pull your child out of school or navigate complicated procedures with school attendance authorities. To ensure their academic progress does not suffer a single second of delay, Del Ferro organizes the intensive 5-day training programs during all official school holidays: autumn, Christmas, spring, May, and summer breaks.
The effect after such a holiday is always extraordinary. Take the story of former Member of Parliament Femke Merel van Kooten. As a child, she was completely silenced by bullies due to her stuttering. Around the age of 14, she completed the training at Del Ferro, became stutter-free, and years later spoke with absolute confidence in Parliament.
When school starts again after the holidays, teachers and internal student counselors are regularly moved to tears: the anxious, quiet child has disappeared. A student walks into the classroom who immediately raises their hand, cracks jokes, and shows their true capabilities. Parents frequently tell us that after years of silence, they are only now truly getting to know their child.
Aftercare: The Physical and Mental Glue
The technique is anchored in just 5 course days, but to ensure the old anxiety doesn’t overtake their speech once again, aftercare is essential. As Ingrid Del Ferro explains: “You are only truly free from stuttering when you also have freedom in your mind.” Weekly contact with the stuttering specialist takes place via online and in-person sessions.
Stop Struggling, Choose a Permanent Solution
Give your son or daughter the freedom to be who they truly are. Use the upcoming school holiday to eliminate the physical block once and for all.
Frequently Asked Questions About Speech Therapy and the School Approach
Why does my child's school always recommend traditional speech therapy?
Schools and internal student coordinators are bound by general protocols and automatically refer every child with a speech or language concern to standard primary care. Because knowledge regarding the physical blockage of the diaphragm muscle is not yet part of their standard training, they are simply unaware of this alternative method. As a parent, you have the freedom to bypass this standard protocol.
Is 5 days during a school holiday truly enough to break a long-standing stuttering pattern?
Yes. The great advantage for children and young people is that their muscle memory is incredibly flexible. As soon as they learn the speech technique, the body instantly understands the logic. From day one, your child will speak stutter-free. The subsequent aftercare period is purely designed to make this completely automatic and a natural habit.
