<p>The working definition of cluttering focuses on speed and irregularity of speech, frequency of normal disfluency, and coarticulation. Cluttering is often comorbid with stuttering. In this study, articulation rates and frequency of disfluency in a picture explanation task were measured in nine cluttering-stuttering students, 10 LD, AD/HD, and/or ASD students, and 24 control students. No significant differences were found between the three groups in terms of articulation rates. The results made clear the necessity to examine a more appropriate measurement target such as free utterance, etc. In addition, the results showed that frequencies of normal disfluency as high as those of the cluttering-stuttering group existed in the LD, AD/HD and/or ASD group.</p>
