초록
Although it is well documented that patients with cochlear implant experience hearing difficulties when processing theirfirst language, very little is known whether or not and to what extent cochlear implant patients recognize segments in asecond language. This preliminary study examines how Korean learners of English identify English segments in a normalhearing and cochlear implant simulation conditions. Participants heard English vowels and consonants in the following threeconditions: normal hearing condition, 12-channel noise vocoding with 0mm spectral shift, and 12-channel noise vocoding with3mm spectral shift. Results confirmed that nonnative listeners could also retrieve spectral information from vocoded speechsignal, as they recognized vowel features fairly accurately despite the vocoding. In contrast, the intelligibility of manner andplace features of consonants was significantly decreased by vocoding. In addition, we found that spectral shift affectedlisteners’ vowel recognition, probably because information regarding F1 is diminished by spectral shifting. Results suggest thatpatients with cochlear implant and normal hearing second language learners would experience different patterns of listeningerrors when processing their second language(s).
