Phoneme recognition and confusions in patients with sensorineural hearing loss

Hearing impaired listeners show different phoneme confusions during speech recognition testing. The aim of the study was to analyze phoneme recognition in patients with sensorineural hearing loss during word recognition testing with monosyllable words, as well as, to compare consonant confusions in different vowel context. Recognition of 18 initial and final consonants was analyzed in a total of 698 presentations of the words. There were 1154 (82.7%) correct recognitions and 100 consonant confusions (7.2%). The patients did not response at a total of 71 presentations of the words which means that consonants in 142 cases (10.2%) were not recognized, nor confused. There are no consonant confusion patterns during suprathreshold testing with real words. In cases of phoneme confusions, listeners replace the stimulus word with another word from the lexical neighborhood. In terms of the vowel context, the consonants are the most easily identified in the context of the vowel /a/. © 2023, Institute for Human Rehabilitation. All rights reserved.
