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…
