This letter reports a study designed to measure the benefits of voicing in the recognition of concurrent syllables. The target and distracter syllables were either voiced or whispered, producing four combinations of vocal contrast. Results show that listeners use voicing whenever it is present either to detect a target syllable or to reject a distracter. When the predictable effects of audibility were taken into account, limited evidence remained for the harmonic cancellation mechanism thought to make rejecting distracter syllables more effective than enhancing target syllables.
这封信报告了一项旨在衡量发声在识别同时出现的音节中的益处的研究。目标音节和干扰音节要么发声，要么轻声，产生了四种声对比组合。结果表明，无论发声是否存在，听众都会利用它来检测目标音节或拒绝干扰音节。当考虑到可听度的可预测影响时，仍然只有有限的证据支持被认为使拒绝干扰音节比增强目标音节更有效的谐波抵消机制。
