A study was carried out to determine which factors contributed to the vowel and consonant recognition ability of recipients of the 22-channel cochlear implant system. On the basis of the statistical analysis, no isolated factor showed a strong correlation with vowel recognition score. On the other hand, negative correlations were found between patients' consonant recognition scores and postoperative psychophysical percepts such as threshold levels and maximum comfortable loudness levels. However, multiple regression analysis also showed that the combination of lower threshold levels, a larger number of usable electrodes, and wider dynamic ranges contributed to higher consonant recognition scores.
开展了一项研究以确定哪些因素有助于22通道人工耳蜗植入系统接受者的元音和辅音识别能力。基于统计分析，没有单一因素与元音识别得分显示出强相关性。另一方面，发现患者的辅音识别得分与术后心理物理学感知（如阈值水平和最大舒适响度水平）之间存在负相关。然而，多元回归分析还表明，较低的阈值水平、较多的可用电极数量和较宽的动态范围相结合有助于提高辅音识别得分。
