In our Q&A session, we answer common questions about stuttering, its causes and how to get rid of it.

How many people stutter?

Worldwide, about 1% of the population stutters, which is about 175,000 people in the Netherlands and about 80 million people worldwide.

What is the cause of stuttering?

Stuttering is seen as learned behavior that is difficult to unlearn without help. Everyone starts stuttering for different reasons and at different times, making a specific cause difficult to identify. However, the physical cause of stuttering is well known and scientifically proven. In the 1970s, Len Del Ferro discovered that uncontrolled movements of the diaphragm muscle cause stuttering.

When the diaphragm muscle moves smoothly upward during speech, it results in smooth speech. In stuttering, however, the diaphragm makes jerky movements, which interrupts airflow and pushes against the vocal cords, resulting in faltering speech or even complete blockages making speaking impossible.

Is stuttering hereditary?

It is sometimes thought that stuttering is hereditary, but there is no scientific evidence for this. The fact that in identical twins, sometimes one child stutters and the other does not indicates a non-hereditary basis.

Stuttering can also occur because children mimic the behavior of stuttering family members. If there is a predisposition to stuttering and someone in the environment stutters, a child may copy this behavior, sometimes leading to a pattern that continues for generations.

Is stuttering mental or physical?

Stuttering is primarily a physical phenomenon, caused by uncontrolled movements of the diaphragm, with often mental-emotional consequences. This can result in overwhelming fears and speech anxiety about certain situations, letters and words.

Stuttering not only affects speech, but touches on all aspects of life, including self-image, self-confidence, social interactions and educational and career choices. It can even be so profound that it affects a person’s desire to live.

Some people with a stuttering problem become isolated and unhappy because of their withdrawnness. Others learn to cope with their stuttering, sometimes by using tricks so effective that their stuttering goes unnoticed.

Is stuttering caused by incorrect breathing?

The diaphragm muscle plays a crucial role in the breathing process, with 90% responsible for breathing. In stuttering, one does not necessarily breathe incorrectly, but during speaking and stuttering, the diaphragm muscle can make uncontrolled movements, which interferes with fluent speaking.

Why does a person not always stutter, sometimes more and sometimes less?

People who stutter experience moments of fluent speech or reduced stuttering. For example, they do not stutter when talking to animals or on “good” days. Some may stutter dramatically but speak completely fluently during a lecture, while others stutter more. Acting seems to go well for many who stutter, possibly because it allows them to play a role.

Stress increases the likelihood of stuttering, especially in situations such as giving presentations, reading aloud or talking on the phone. People who stutter may also have a fear of specific letters or words. Everyone stutters in a unique, personal way; what is challenging for one person may be easy for another.

Stuttering therefore varies by person and situation, with no one stuttering constantly. Discovering a technique that prevents stuttering offers the reassurance that speaking can always be fluent.

Why doesn't someone stutter when singing?

During singing, continuous control is exercised over the diaphragm, causing this muscle to automatically make smooth movements, resulting in an uninterrupted flow of sounds. This same fluid movement is necessary for speaking; however, in people who stutter, this fluid movement does not always take place.

Can stuttering go away by itself?

Stuttering usually occurs between the second and sixth years of life, a period when many children temporarily become less fluent. About 4% of children repeat words, stammer, or stumble over their words. This is understandable, since speaking is a complex process that requires a lot of practice. At this stage, vocabulary grows rapidly, while knowledge of sentence structure and speech motor skills are still developing.

This type of stumbling speech, which often occurs in a relaxed manner, is called primary stuttering and is distinct from true stuttering. This usually disappears again on its own. However, about one in three of these children begin to really stutter after a period of primary stuttering, during which hesitation changes from relaxed to tense.

Can you get rid of stuttering?

It is possible to fully recover from stuttering at any age. The Del Ferro method, with over 45 years of experience, has shown that both children and adults can completely overcome their stuttering. This stutter therapy is based on training the diaphragm muscle.

The method also focuses on the mental aspects, including addressing social-emotional problems often associated with stuttering, as well as strengthening self-confidence and reducing anxiety. An important condition for success, however, is that the person himself or herself is motivated to participate in therapy and is determined to overcome his or her stuttering.
