Acoustic measures of stutterers' speech following an intensive therapy program

Characteristics of consonant-vowel duration and vocal fundamental frequency ( F 0) are reported for 12 school-age stuttering males. Subjects' speech was recorded pre- and post- therapy and at 2-mo follow-up. Mean F 0 and voice onset time values remained stable from pretherapy to 2-mo follow-up,...

Description
Summary:Characteristics of consonant-vowel duration and vocal fundamental frequency ( F 0) are reported for 12 school-age stuttering males. Subjects' speech was recorded pre- and post- therapy and at 2-mo follow-up. Mean F 0 and voice onset time values remained stable from pretherapy to 2-mo follow-up, and an increase of 12% vocalized time was maintained across all posttherapy samples. It is suggested that increases in speech fluency may not be accompanied by changes in fundamental timing gestures. Increased speech fluency may be accomplished through increases in vocalized time permitting adjustments in motor sequencing which accompany stuttering.
