Note. As indicated by the range of SLDs per 100 syllables, a value of less than 3 was calculated for some CWS. This occurred because the SLD measure reflects the average of multiple 100-syllable speech segments from two conversational settings. However, the criterion number of SLDs per 100 syllables for classification as a CWS was met if the child demonstrated 3 or more SLDs in any one of these 100-syllable segments (Yairi & Ambrose, 1999). Therefore, all CWS still met this criterion for stuttering classification.
