Adaptive speech audiometry and speech discrimination space in hearing-impaired subjects.
Phonemic discrimination difficulties in a small group of patients with sensorineural hearing loss have been mapped using a new form of speech audiometry which is au automated, adaptive, audio-visual system, using a binary forced-choice response mode. Phonemic confusion patterns have been displayed in directed graph form and the cases presented here have been chosen to illustrate the potentialities of the test method for obtaining detailed information on the fine structure of speech reception in these patients.
