Which factor is NOT included in the characteristics of disfluency?

The correct choice indicates that rapid speech that flows easily is not considered a characteristic of disfluency. Disfluencies typically involve interruptions and disruptions in the flow of speech, such as hesitations, repetitions, or blocks that can be accompanied by tension. When speech flows rapidly and easily, it suggests a smooth and fluent speech pattern rather than the challenges associated with disfluency.

In contrast, factors such as excessive tension during speech, repetitions of sounds or words, and blocks during sound initiation are all indicators of disfluency, as they highlight difficulties a person may experience in maintaining a smooth flow of speech. These characteristics reflect the struggle individuals may face while attempting to communicate, which is central to understanding disfluency.
