^aSomeofthe CWS are recorded as having fewerthan three SLDs per 100 syllables, but they still met the criteria forthe stuttering diagnosis. This occurred, because the SLD measures listed are the result of averaging across the multiple 100 syllable segments of speech available from two conversational settings. If in one of these 100 syllable segments, the child exceeded three stuttering-like disfluencies, he or she was judged to meet this criterion forthe stuttering diagnosis (Yairi & Ambrose, 1999).
