This study investigated adult cochlear implant users' (n == 39) vowel recognition and confusions by an open-set syllable test during 4 years of implant use, in a prospective repeated-measures design. Subjects' responses were coded for phoneme errors and estimated by the generalized mixed model. Improvement in overall vowel recognition was highest…

Peer reviewedValimaa, Taina T.; Maatta, Taisto K.; Lopponen, Heikki J.; Sorri, Martti J. – Journal of Speech, Language, and Hearing Research, 2002
A study investigated how 19 Finnish adults who were postlingually severely or profoundly hearing impaired would relearn to recognize vowels after receiving multi-channel cochlear implants. Average vowel recognition was 68% 6 months after switch-on, and 80% 24 months after switch-on. Vowels y, e, and o were most difficult. (Contains references.)…

Peer reviewedValimaa, Taina T.; Maatta, Taisto K.; Lopponen, Heikki J.; Sorri, Martti J. – Journal of Speech, Language, and Hearing Research, 2002

Two years after the switch-on, the mean recognition for consonants was 71%. Consonants with alveolar, palatal, or velar transitions were better recognized.…
