目的：研究语言和语音相近（英语和荷兰语）和距离较远（英语和普通话）语言对的掩码释放情况。方法：32名听力阈值正常的英语单语者参与研究。本文报告了英语句子识别任务、荷兰语和普通话语音掩蔽器（实验1）和噪声掩蔽器（实验2）的数据，这些数据与实验1中语音掩蔽器的长期平均语音频谱或时间调制相匹配。结果：听者表现随目标-掩蔽者语言距离的增加而增加（英语-英语<荷兰语-英语<汉语-英语）。结论：掩体之间的光谱差异可以解释掩体之间性能差异的部分原因，但不是全部原因；然而，时间差异似乎没有发挥重要作用。
Purpose: To investigate masking release for speech maskers for linguistically and phonetically close (English and Dutch) and distant (English and Mandarin) language pairs.Method: Thirty-two monolingual speakers of English with normal audiometric thresholds participated in the study. Data are reported for an English sentence recognition task in English and for Dutch and Mandarin competing speech maskers (Experiment 1) and noise maskers (Experiment 2) that were matched either to the long-term average speech spectra or to the temporal modulations of the speech maskers from Experiment 1.Results: Listener performance increased as the target-to-masker linguistic distance increased (English-in-English < English-in-Dutch < English-in-Mandarin).Conclusion: Spectral differences between maskers can account for some, but not all, of the variation in performance between maskers; however, temporal differences did not seem to play a significant role.
