Speech Blocks in Stuttering: Why They Happen & How to Move Through Them
Quick Summary
- What a block is: A moment where no sound comes out because the voice and speech muscles tense or “freeze,” often at the very start of a word.
- Why it happens (the short version): Speaking is complex; sometimes the “system” overloads (like a computer crash). Techniques that simplify speech reduce the processing load so speech can start and keep moving.
- Techniques that can help:
- Prolonged speech
- Continuous phonation
- Easy onsets
- Soft contacts
What is a speech block?
A speech block is a moment in stuttering/stammering where no sound comes out because the voice and speech muscles tense or “freeze,” often at the very start of a word. Speech techniques can help reduce tension and prevent or ease blocks - for example, prolonged speech, easy onsets, soft contacts or continuous phonation.
What is a speech block?Speech blocks can be hard to explain to people who have not experienced them. Blocks often feel like air is stuck or the throat is closed. You might press your lips or tongue hard, or hold your breath. Think of it as two forces in opposition: part of you pushes the word out; part of you braces and holds back. The result is no voice and rising tension.
Why speech techniques can help (even for blocks on the first sound)A helpful analogy is to imagine your brain as a computer and speech as a demanding piece of software running on it. Speech is extraordinarily complex - if you want an idea, look at a live MRI of the oral cavity during speech. Even that doesn’t show everything, since the speaker is also coordinating vocal folds, breathing, and many other processes at the same time.
Given this complexity, there are moments where the “computer” becomes overloaded. Blocks or other moments of stuttering are like the errors or crashes that happen when a system can’t cope with the demands placed on it.
Speech techniques like prolonged speech, easy onsets, and continuous phonation can reduce the processing load of speech, helping with blocks (as well as stuttering/stammering more generally).
Why blocks happen at the first soundWhen we block, it’s not just the first sound that’s difficult - it’s the complexity of producing the whole phrase or sentence. Many people who stutter can say a challenging sound (like “p”) on its own. The difficulty arises when that sound is combined with the rest of the word or phrase. The system isn’t struggling with a single sound; it’s preparing the whole program of connected speech that can overload the system.
My personal experience of learning to manage speech blocks:
I avoided prolonged speech for a long time because my blocks always came on the very first sound. I often wondered: “How can I prolong speech if I can’t even start?” What I’ve found is that if I set the intention beforehand and then gently prolong the whole phrase - from the very first sound to the very last - the blocks at the start reduce dramatically. If I focus only on the tricky first sound (for example, the “e” in “excuse me”) and try to apply a technique there alone, I still block - because I’m not prepared for the rest of the phrase. The key is to deliberately prolong the whole phrase, not just the difficult sound or word. So, instead of “Eeeeexcuse me” you would say “Eexxccuussee mmee.” Thinking back to the computer/software analogy above, prolonging only the first sound does not reduce the processing demand enough for me. By planning a little prolongation evenly across the entire phrase, that initial sound then becomes much easier to produce. FAQs
What is a speech block in stuttering/stammering?
A block is a silent moment where speech doesn’t start because the voice and speech muscles tense. It often happens at the start of a word or sentence. It can be a hard thing to explain to people who do not stutter. When it occurs it feels like a physical block in the throat of mouth. Why do I block on the first sound? It’s usually not just that sound; it’s the overall load (speed, pressure, anticipation). Your larynx and articulators brace, and voice won’t start. How do I stop a block as it happens? Release tension, take a small breath, use an easy onset, and prolong the whole phrase with continuous voice. Avoid pushing. Does prolonged speech work for first-sound blocks? Yes--if you start the entire phrase in prolonged mode and keep voice flowing, rather than trying to stretch a sound after you’re already stuck. Is prolonged speech the same as continuous phonation? Related. Prolonged speech stretches sounds; continuous phonation keeps voice on between words. Together they reduce starts/stops that trigger blocks. Are blocks psychological? Blocks are speech-motor events influenced by context, pressure, and anticipation. Mindset matters, but the immediate problem is tension and timing, not willpower. Should I see a speech and language therapist? If blocks are frequent or stressful, yes. An SLT can tailor fluency-shaping and stuttering modification approaches to your needs. They’ll match the plan to your goals - fewer blocks, less struggle, or easier communication. |
