Fluency refers to a smooth, continuous rate of speech. A fluency disorder is known when speaking becomes more effortful like with repetitions of sounds/syllables/words/phrases (e.g., b-b-b-baby), holding sounds out for a longer period of time (e.g., sssssssssssometimes), and/or as blocks (e.g., inaudible or silent fixation or inability to initiate sounds).
