The aim of this study was to investigate phoneme recognition in postlingually deafened adults with cochlear implantation. 21-cochlear implantee were participated. They was used cochlear implants more than 1 year. In order to measure consonant performance abilities, subjects were asked for 18 items of Korean consonants in a "aCa" condition with audition alone. The scores ranged from 11 to 86 ($60{\pm}17$)%. The consonant performance abilities correlated with implanted hearing threshold level, significantly (p<.046). This results suggest that consonant performance abilities of postlingual deafened adults cochlear implantee be important for implanted hearing. They had higher correct rates for fricatives and affricatives with distinctive frequency bands than for plosives, liquids & nasals with the same or adjacent frequency bands. All subjects had confusion patterns among the consonants of the same manner of articulation. The reason of consonant confusions was caused that they couldn't recognize different intensities and durations of consonants with the same or adjacent frequency bands.
