Abstract
The purpose of this study was to determine whether patterns of phoneme identification errors differ as a function of signal presentation level among listeners with cochlear and retrocochlear auditory disorder. An analysis of the speech intelligibility performance of 15 patients with confirmed eighth nerve disorder was conducted, using confusion matrices derived from responses to a monosyllabic word list. The same analysis was conducted on the responses of a group of 15 patients with cochlear disorders, matched to the retrocochlear group for age and audiometric configuration. The results indicated that: (1) vowel errors were more prevalent and varied directly with increasing stimulus presentation level in the retrocochlear group; and (2) consonant errors did not differ in type or relative frequency between the two groups, nor was there a level‐dependent effect. These results are supported by closed‐set vowel identification tests and thus do not appear to be an artifact of open set testing. Vowel errors may account for a major part of the speech “rollover” phenomenon typical of retrocochlear dysfunction.
