The Webster diacritical system provides a discrete symbol for each sound and designates the appropriate syllable to be stressed in any polysyllabic word; the symbol system presents cues for correct production, auditory discriminiation, and visual recognition of new words in print and as visual speech gestures. The Webster's Diacritical CAI Program is designed to provide cognitive skill in recognizing and using diacritical markings for newly employed faculty and staff at the National Technical Institute for the Deaf (NTID), and NTID students who have some auditory discrimination for speech. Photographs of a speaker producing the vowels and diphthongs were assembled in a handbook to use while viewing the CAI portion of the program which was developed for an IBM 1130/1500 system using cathode-ray tube and random access audio unit. Audio messages consisting of the sounds and words used in the program were recorded and inserted in the program. Pretest and post-test data accumulated for 40 new staff members and for 55 students indicate that the CAI program meets the individual needs of both students and faculty. Sequential frames demonstrating the instructional strategy and a flow chart designating the order of presentation are appended. (DAG)
