Abstract
The responses of 36 hard-of-hearing subjects from three different language groups to logatomes were analysed by an information transmission statistic involving seven distinctive features of consonant phonemes. The percent-information transmission values associated with the seven distinctive features for each of the three language groups were plotted and ranked from the most weighted to the least weighted features. These plottings have been called “Feature-Grams” since they contain crucial diagnostic information regarding the hearing impaired subjects' phonemic repertoires. A comparison of the “Feature-Grams” and the pure tone audiograms show the importance of the former in the realistic assessment of the patients' hearing for speech sounds.
