What is stammering?

Stammering, also known as stuttering (both mean the same thing), is a neuro-developmental condition where someone repeats, stretches and/or gets stuck when they are speaking. It is different from typical hesitations and rewordings.

It is estimated that 8% or 1 in 12 children stammer at some point. Many of these children will resolve their stammer naturally within a few months. However, 1 in 50 adults continue to stammer, with men 3-4 times more likely to stammer than women. 

There are both ‘overt’ characteristics that can be seen and heard, and ‘covert’ characteristics that are emotional, psychological and behavioural. 

Overt characteristics

Overt characteristics are those that can be heard and seen when the person is speaking and can include: 

• repeating sounds, syllables, or words (e.g. "k-k-king")
• lengthening sounds (e.g. "lllllake")
• stopping or ‘blocking’ speech sounds, where the person is unable to produce sounds easily
• visible tension in the face, breathing and body

Covert characteristics

Covert characteristics, on the other hand, refer to the internal experiences associated with stammering, which can go unnoticed by family, friends and colleagues

• feelings of anxiety, frustration and embarrassment relating to speaking
• avoidance of words and speech sounds that are difficult for the person to say, such as the person’s own name or certain sounds in words
• avoidance of speaking situations where the stammer increases, such as speaking on the phone or giving presentations

The frequency of stammering moments and how much the stammer affects a person varies greatly. You can learn more in the articles in this section.
