Word boundaries of 30 sentences spoken by deaf children were acoustically marked by means of silent pauses between words. Subsequent tests with normal-hearing listeners demonstrated that after insertion of pauses the intelligibility of the sentences increased significantly. Results are compared to studies in which segmental and suprasegmental…

The contribution of reduced speaking rate to the intelligibility of "clear" speech was evaluated by adjusting the durations of speech segments in various ways for both hard-of-hearing listeners and listeners with normal hearing. The intelligibility advantage of clear speech over conversational speech was confirmed for both groups of…

Properties of the Vowel Corrector, a visual aid used in speech training of the hearing impaired, are examined. Implications for differentiating utterances of male, female, and child speakers are studied. Results show that the device has promising features and is especially useful for exploring the vowel space and learning a global differentiation…

The study of 20 adult stutterers participating in a 32-hour program of fluency training found that results were consistent with the hypothesis that improvements in fluency during response-contingent stimulation may occur when stutterers access extant fluent speech that is not otherwise being fully utilized.

Glossometry, a method of providing visual feedback of tongue positions, was used to teach four vowel sounds to six profoundly hearing-impaired children. After 15 to 20 50-minute training sessions, all subjects showed greater diversification of tongue postures for the vowels. Listener identifications were also generally better after therapy.…

The speech of 12 adults in prolonged speech treatment was assessed prior to treatment and after discharge. Results showed that stuttering was eliminated without using unusually slow or unnatural speech patterns, and many clients maintained stutter-free speech at high rates of speech. Speech rate correlated to perceived posttreatment speech…

Preschool children (n=27) were followed for 2 to 12 years after stuttering onset. Findings indicated a marked deceleration in the mean frequency of stuttering-like disfluencies. Most of the reduction took place early, especially near the end of the first year postonset. Chronic and recovering stutterers could be distinguished by 20 months…

Two operant speech treatment programs for establishing fluent speech--Delayed Auditory Feedback and Gradual Increase in Length and Complexity of Utterance--were compared, with 24 elementary-secondary level students. Both programs produced important improvement in fluency in a reasonable time period and resulted in similar levels of transfer and…

Testing of 17 adult and 25 adolescent stutterers during a 12-month to 24-month postintensive treatment phase revealed that 69% of subjects maintained satisfactory fluency on surprise phone calls at home/work and 80% of subjects rated their speech fluency as good or fair on the Speech Performance Questionnaire.

Five profoundly hearing-impaired children were taught to speak seven consonant sounds using palatometry which allows learners to see tongue-to-palate contact patterns used in sound production. Results demonstrated that visual articulatory modeling and feedback of linguapalatal contact patterns is an effective means of teaching consonants and…

Speech language pathologists providing early intervention services for stuttering are urged to evaluate conceptual and practical aspects of various intervention procedures. After a review of three treatment methods (environment manipulation, prolonged speech, and response-contingent stimulation), the article concludes that response-contingent…

Sixteen preschool subjects were evaluated within several weeks after stuttering onset and followed for six months. Findings showed a strong tendency for reduction in stuttering-like disfluencies, number of head/face movements, and parent and clinician severity ratings of stuttering. Several subjects, including severe cases, exhibited complete…

A study investigated the long-term effects of a Botulinum Toxin Type A injection on the glottal competency of a man with adductor spasmodic dysphonia. Results suggest that change in degree of glottal adduction over time can be observed even when vocal instability is present within each recording session. (CR)
