HyunSub Sim. Acoustic Analysis of Stuttering Children s Fluent Speech: Preand Post Therapy . K orean J ournal of Communicat ion D isorders, 2 , 119136. This study compared absolute durations of temporal acoustic parameters at the subsegmental level of fluent speech produced by stuttering children (N = 4) before and after Normal T alking Process therapy. These measures were compared with those of an ageand gender matched control group of normally fluent children. The findings indicated that voice onset time (VOT ) and CV(consonantvowel) transition duration decreased significantly after therapy. Children who stutter produced significantly longer vowel duration than control group both before and after therapy. The results were discussed in light of differential aspects of the treatment .
