Disfluency

Any interruption or break in the normal flow of speech, including repetitions, prolongations, blocks, interjections (such as "um" or "uh"), and revisions. While all speakers experience occasional disfluencies, their frequency and severity distinguish typical speech from stuttering and other fluency disorders. In speech technology and AI research, disfluency detection and classification is an active area involving machine learning systems trained on annotated speech samples to automatically identify and categorize different types of disfluencies for clinical assessment purposes.
