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.…

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…

The influence of visual signals (echo and reverberation) on speech fluency in 60 stutterers and nonstutterers was examined. Visual signals were found to exert a corrective influence on the speech of stutterers but less than the influence of acoustic stimuli. Use of visual signals in combination with acoustic and tactile signals is recommended. (DB)

Fifteen stutterers (aged 5-16) were treated using graded airflow, tension/relaxation, and electromyographic biofeedback to reduce stuttering frequency. In a second study, addition of a discriminative stimulus control procedure to maintain fluency made the treatment program more effective than the first study and achieved a level of <1% stuttered…
