Disfluency
Disfluency refers to any interruption or disruption in the natural flow of speech. This can manifest in various ways, including repetitions of sounds, syllables, or words; prolongations of sounds; interjections like "um" and "ah"; silent pauses; and broken words. Disfluencies are common in all speakers to some extent, but when they occur frequently or with excessive effort, they may indicate a communication disorder such as stuttering or cluttering. The study of disfluency is crucial in speech-language pathology, where understanding its nature helps in diagnosing and treating speech impediments, improving communication effectiveness, and reducing any associated social or psychological impact. The assessment of disfluency often involves analyzing the type, frequency, and duration of these interruptions.
