International Stuttering Awareness Day is celebrated on October 22, 2023. The day is intended to raise public awareness of the millions of people - one per cent of the world's population - who have the speech disorder of stuttering, also known as stammering. ISAD is organised by three organizations: European League of Stuttering Associations, International Fluency Association and International Stuttering Association.
Stuttering is a speech disorder in which the flow of speech is disrupted by involuntary repetitions and prolongations of sounds, syllables, words or phrases as well as involuntary silent pauses or blocks in which the person who stutters is unable to produce sounds. The term stuttering is most commonly associated with involuntary sound repetition, but it also encompasses the abnormal hesitation or pausing before speech, referred to by people who stutter as blocks, and the prolongation of certain sounds, usually vowels and semivowels.
For many people who stutter, repetition is the primary problem. The impact of stuttering on a person's functioning and emotional state can be severe. This may include fears of having to enunciate specific vowels or consonants, fears of being caught stuttering in social situations, self-imposed isolation, anxiety, stress, shame, being a possible target of bullying, having to use word substitution and rearrange words in a sentence to hide stuttering, or a feeling of "loss of control" during speech.
