Do normal speakers produce disfluencies?

Normal speakers do indeed produce disfluencies, though it typically occurs only occasionally. Disfluencies are breaks or disruptions in the flow of speech, which can include fillers like "um" or "uh," repetitions of words or phrases, or hesitations. These are a natural part of spoken language and can happen for various reasons, such as organizing thoughts, speech planning, or dealing with unexpected conversational turns.

The occurrence of disfluencies among normal speakers reflects the complexity of language processing in real-time communication. Everyone experiences these to some extent, particularly during spontaneous conversation, indicating that disfluency is a normal aspect of speech rather than a sign of a speech disorder.

In contrast, the other options suggest absolute or excessive occurrences of disfluencies which do not accurately represent typical speech patterns in fluent speakers. Normal communication often involves smooth discourse with occasional interruptions, highlighting that disfluencies are part of natural speech processes rather than signs of incapacity.
