频谱-时间退化的差异可以解释人工耳蜗使用者语音结果的一些变化。本研究采用声码器模拟具有典型听力的听众，以评估不同程度的通道相互作用的耳朵如何影响空间语音识别。在16名听力正常的受试者中测量了模拟双侧人工耳蜗植入的语音识别阈值和掩蔽的空间释放。16-通道正弦声码语音模拟有限的，广泛的，或混合通道的相互作用，在双耳分音和双耳目标掩蔽条件下，跨越耳朵。双耳中的宽通道相互作用的耐受性最高，但当一只耳朵和双耳中的相互作用降低时，耐受性得到改善。掩蔽释放在各种条件下都很明显。对具有典型听力的听者的模拟研究结果表明，通道交互可能比掩蔽释放更影响语音识别，并且可能对通道交互对人工耳蜗用户的语音识别结果的影响产生影响。
Differences in spectro-temporal degradation may explain some variability in cochlear implant users’ speech outcomes. The present study employs vocoder simulations on listeners with typical hearing to evaluate how differences in degree of channel interaction across ears affects spatial speech recognition. Speech recognition thresholds and spatial release from masking were measured in 16 normal-hearing subjects listening to simulated bilateral cochlear implants. 16-channel sine-vocoded speech simulated limited, broad, or mixed channel interaction, in dichotic and diotic target-masker conditions, across ears. Thresholds were highest with broad channel interaction in both ears but improved when interaction decreased in one ear and again in both ears. Masking release was apparent across conditions. Results from this simulation study on listeners with typical hearing show that channel interaction may impact speech recognition more than masking release, and may have implications for the effects of channel interaction on cochlear implant users’ speech recognition outcomes.
