The way we speak and communicate is part of our personality, and even our identity. When it comes to speaking, there are people who have fluent and appropriate speech, with very occasional mistakes, and people who tend to make mistakes more frequently, or to repeat some syllable or word of their speech. We can all go from being more to less fluent depending on the moment, whether we are focused or have a prepared speech, presenting good fluency; or that we are tired or nervous, and we are more clumsy when it comes to speaking. Even so, there are people who tend to have poor fluency in speech on a chronic basis, presenting constant repetitions of syllables at the beginning of a sentence, taglines, or even gestures associated with when they get stuck in a word.
What is stuttering?
Stuttering, also called dysphemia, is a speech disorder. The speech of people who stutter is characterized by repetitions or prolongations of sounds, syllables, or words. Their speech can also present interruptions in the flow of speech, called blockages, have associated expressions or movements (spasms) and muscle tension in face and neck.
Stuttering often appears in children as part of language development, in the same way that it tends to disappear. It is more common in boys than girls, and approximately 25% of children will stutter when they start to speak. Still, only 1% of people who stutter in childhood continue to do so into adulthood.
