Cochlear implant (CI) users have greater difficulty perceiving talker sex and spatial cues than do normal-hearing (NH) listeners. The present study measured recognition of target sentences in the presence of two co-located or spatially separated speech maskers in NH, bilateral CI, and bimodal CI listeners; masker sex was the same as or different than the target. NH listeners demonstrated a large masking release with masker sex and/or spatial cues. For CI listeners, significant masking release was observed with masker sex cues, but not with spatial cues, at least for the spatially symmetrically placed maskers and listening task used in this study.
与听力正常（NH）的听者相比，人工耳蜗（CI）使用者在感知说话者性别和空间线索方面存在更大困难。本研究测量了NH听者、双侧CI听者和双模式CI听者在存在两个位于同一位置或空间分离的语音掩蔽声时对目标句子的识别；掩蔽声的性别与目标相同或不同。NH听者在掩蔽声性别和/或空间线索方面表现出较大的掩蔽解除。对于CI听者，至少在本研究中使用的空间对称放置的掩蔽声和听力任务中，在掩蔽声性别线索方面观察到了显著的掩蔽解除，但在空间线索方面未观察到。
