Frequency of word occurrence in communication samples produced by adult communication aid users.

Communication samples generated by five nonspeaking adults using Canon Communicators were collected for 14 consecutive days. Samples were analyzed to determine frequency of word occurrence. A core vocabulary of the 500 most frequently occurring words was analyzed further to determine spelling level and proportion of complete communication samples represented by subsets of the core vocabulary list. The 500 core vocabulary words represented 80% of the total words in the combined communication samples for the 5 subjects. Of all messages generated by the subjects, 33% could be communicated in their entirety using words from the core vocabulary list. The communication of the remaining messages required one or more words in addition to the core vocabulary. The spelling grade level of the words in the core vocabulary list did not exceed the seventh grade. The implications of the results for designing and customizing communication aids and for potential user training are discussed.

Microcomputer-based communication augmentation systems for two nonspeaking, physically handicapped persons with severe visual impairment.

Two different microcomputer-based communication systems were developed for nonspeaking physically handicapped individuals with severe visual impairment. One subject was 24 years old and had an inoperative optic glioma which impaired motor function as well as vision. The second subject was cortically blind with severe motor limitation secondary to an automobile accident which occurred at 17 years of age. Both communication systems employed speech synthesis as a control feature to compensate for visual impairment. Both subjects have learned to use their communication systems. The second subject has not achieved extended, independent system use due to reduced vigilance and attention span.
