Abstract
Stuttering therapy procedures such as rhythmic or prolonged speech have been criticized because afterward the subject may speak fluently but also abnormally. Although assessments of the normalcy of speech behavior have been rare, some recent procedures have included perceptual assessments of certain dimensions of speech behavior. This study reports an evaluation procedure where listeners endeavored to distinguish between intermingled speech samples obtained from treated stutterers and a peer group of normally fluent speakers. Different groups of listeners were asked to judge the prosody, rate, fluency, and naturalness of posttreatment samples from a group of stutterers treated with a prolonged speech procedure, and a matched peer group of normally fluent speakers. No significant differences were found between the assessments of stutterers and normally fluent speakers. However, when another group of listeners was asked to decide whether the speech samples were from treated stutterers or normal speakers, the stutterers received significantly fewer normal speaker judgments. Interrelationships between the judgment scales were evaluated along with a forced-choice procedure for assessing the normalcy of individual speech samples.
