Fluency is the aspect of speech production that refers to continuity, smoothness, rate, and effort. Stuttering, the most common fluency disorder, is an interruption in the flow of speaking characterized by repetitions (sounds, syllables, words, phrases), sound prolongations, blocks, interjections, and revisions, which may affect the rate and rhythm of speech. These disfluencies may be accompanied by physical tension, negative reactions, secondary behaviors, and avoidance of sounds, words, or speaking situations (ASHA, 1993; Yaruss, 1998; Yaruss, 2004). Cluttering, another fluency disorder, is characterized by a perceived rapid and/or irregular speech rate, which results in breakdowns in speech clarity and/or fluency (St. Louis & Schulte, 2011).
