Abstract

Objectives: The purpose of this study was to find a correlation between cochlear implant performances in phoneme discrimination and activity of the brain-stem.

Methods: Electrically-evoked auditory brain-stem responses (EABRs) and speech recognition performances were measured in 17 patients implanted with an MXM Digisonic DX10 cochlear implant. Speech recognition performances without lip-reading were tested using lists of isolated French words containing 3 phonemes.

Results: The results indicated statistically significant correlations between phoneme correct-identification scores and the following EABR variables: wave V latency, wave II–V latency interval and wave III–V latency interval. These results, indicate that up to about 48% of the variance in isolated word recognition without lip-reading can be accounted for by EABR variables.

Conclusion: The quality of brain-stem functioning influences central processes in phoneme discrimination.

人工耳蜗植入性能与电诱发听觉脑干反应特征

目的:探讨人工耳蜗在音素识别方面的表现与脑干活动的关系。方法:观察17例植入MXM Digisonic DX10人工耳蜗患者的电诱发听觉脑干反应(EABRs)和语音识别性能。在没有唇读的情况下，使用包含3个音素的孤立法语单词列表测试语音识别性能。结果:音素正确识别得分与以下EABR变量:V波潜伏期、II-V波潜伏期和III-V波潜伏期具有统计学意义。这些结果表明，在没有唇读的情况下，高达48%的孤立单词识别方差可以由EABR变量解释。结论:脑干功能的好坏影响着音素辨别的中枢过程。
