Ten patients who use the Ineraid cochlear implant were tested on a consonant identification task. The stimuli were 16 consonants in the "aCa" environment. The patients who scored greater than 60 percent correct were found to have high feature information scores for amplitude envelope features and for features requiring the detection of high-frequency energy. The patients who scored less than 60 percent correct exhibited lower scores for all features of the signal. The difference in performance between the two groups of patients may be due, at least in part, to differences in the detection or resolution of high-frequency components in the speech signal.
对10名使用Ineraid人工耳蜗的患者进行了辅音识别任务测试。刺激音是处于“aCa”环境中的16个辅音。正确率高于60%的患者在幅度包络特征以及需要检测高频能量的特征方面具有较高的特征信息分数。正确率低于60%的患者在信号的所有特征方面得分较低。两组患者在表现上的差异可能至少部分归因于语音信号中高频成分的检测或分辨率的差异。
