What Is Stuttering?

Most people recognize stuttering when they hear someone repeat a sound or get stuck on a word.

But there is much more to stuttering than what we hear.

This article explores what stuttering is, how it happens, and how it can affect the experience of communication.

Stuttering Begins With Speech

Speaking feels automatic. We think of something to say, and the words seem to come out almost instantly.

But behind every sentence, the brain and body complete a complex series of steps.

First, the brain chooses the words and arranges them into a message. Then it creates a plan for how those words will be spoken.

That plan has to coordinate breathing, voice, and dozens of small, precise movements of the lips, tongue, jaw, and throat, all within fractions of a second.

And somehow, most of the time, it all happens without us consciously thinking about any of it.

Our ability to speak depends on the brain and speech system working together with precise timing and coordination.

Human speech is a miracle.

The process looks something like this:

As speech and language develop during the toddler and preschool years, some children develop differences in the timing and coordination of these speech processes. Those differences can lead to developmental stuttering.

Stuttering can show up in several ways.

What Stuttering Looks and Sounds Like 

Repetitions 

The most common way stuttering shows up is through repetitions.

Most people have repeated whole words or even whole phrases, usually when they're still thinking about what they want to say.

"We might say... we might say... we might say..."

Or...

"Or... or... or..."

But people who stutter know exactly what they want to say.

The difference is that they experience a brief disruption in the timing and coordination of speech. Instead of repeating whole words or phrases, they may g-g-g-get stuck on the beginning sound of a word.

Prolongations

Some people experience prolongations.

A prolongation happens when a sound is stretched out.

"Ssssssometimes..."

"Mmmmmmy..."

It's almost like the sound gets stuck in slow motion.

Blocks

Some people also experience blocks.

A block happens when the mouth is ready to speak, but no sound comes out.

Many people describe it as feeling like the word is stuck or trapped.

"I want to... (block)... get this word out."

So, stuttering begins in the brain and may show up as repetitions, prolongations, or blocks.

But that's only part of the story.

What Stuttering Isn't

If there's one misconception I'd love to clear up, it's this:

Stuttering isn't caused by anxiety.

It isn't caused by talking too fast.

And it isn't something people choose to do.

People who stutter know exactly what they want to say, but sometimes they experience a temporary disruption in the timing and coordination of speech while they're speaking.

Understanding that changes the way we think about stuttering.

It also helps explain why well-meaning advice like "Slow down," "Take a deep breath," or "Think about what you want to say" usually isn't helpful.

Those suggestions don't change the timing and coordination of speech in the brain. For many people who stutter, they can actually add pressure at a time when speaking already feels difficult.

Key Takeaway

People who stutter know what they want to say. Stuttering is a difference in the timing and coordination of speech.  It is not a lack of intelligence, effort, or preparation. 

Why Does Stuttering Change?

One of the most confusing things about stuttering is that it often changes. We call this variability.

Someone may stutter more one day and less another day.

They may stutter more with certain people or in certain situations.

They may even stutter on a specific word one time and say that exact same word easily another time.

Sometimes, someone may stop stuttering for a long period of time, even years, only to have it return again.

Variability can be one of the most confusing and frustrating parts of the stuttering experience because it reminds us just how inconsistent stuttering can be.

Stuttering, by its very nature, is unpredictable.

There’s More to the Experience of Stuttering

So far, we've talked about where stuttering begins, what it sounds like, and why it can change from day to day.

But there's another important piece of the story.

The experience of stuttering isn't limited to what we hear. For many people, it also includes thoughts, feelings, and everyday experiences around communication.

When we're faced with something that's difficult and unpredictable, it's only natural that we begin responding to it and even protecting ourselves from it.

We may avoid certain words because we think we might stutter on them.

We may switch words at the last second or ask someone else to order for us at a restaurant.

We may avoid raising our hand in class, introducing ourselves, or speaking in meetings.

We may begin to feel nervous about talking, not because nervousness caused the stuttering, but because talking has become difficult.

We may feel frustrated, embarrassed, or pressured to get our words out perfectly.

And sometimes, the struggle around stuttering becomes bigger than the stuttering itself.

The Bottom Line

Stuttering is much more than repeating sounds or getting stuck on words.

It's a unique communication experience that can affect not only speech, but also thoughts, feelings, and everyday life.

The more we understand stuttering, the less likely we are to blame the person who stutters for something they didn't choose.

Understanding helps replace judgment with compassion.

The more we understand stuttering, the better we can support the people who live with it every day.

When we know better, we do better.
