Many variables affect the audiologic performance of cochlear implantees. With current methods of evaluation, it is difficult to directly compare auditory function with different speech coding strategies. We compared the audiologic performance directly with F0F1F2 and multipeak speech coding strategies in the same implanted ear of eight Korean cochlear implantees. We tested word and phoneme recognition abilities using Korean word lists for speech audiometry and two-syllable nonsense words, respectively. With the multipeak coding strategy, a significant difference in discrimination ability was found in the initial fricative consonant phonemes (/s/,/ss/,/h/). Our results suggest that the improvement of speech recognition ability with the multipeak coding strategy comes primarily from the better understanding of the initial fricative consonants.
许多变量会影响人工耳蜗植入者的听力表现。采用当前的评估方法，很难直接比较不同语音编码策略下的听觉功能。我们在八名韩国人工耳蜗植入者的同一只植入耳中，直接比较了F0F1F2和多峰语音编码策略的听力表现。我们分别使用韩语单词列表进行言语测听以及双音节无意义单词来测试单词和音素识别能力。采用多峰编码策略时，在初始摩擦辅音音素（/s/、/ss/、/h/）的辨别能力上发现了显著差异。我们的结果表明，多峰编码策略带来的语音识别能力提升主要源于对初始摩擦辅音的更好理解。
