English consonant recognition in undegraded and degraded listening conditions was compared for listeners whose primary language was either Japanese or American English. There were ten subjects in each of the two groups, termed the non-native (Japanese) and the native (American) subjects, respectively. The Modified Rhyme Test was degraded either by a babble of voices (S/N = -3 dB) or by a room reverberation (reverberation time, T = 1.2 s). The Japanese subjects performed at a lower level than the American subjects in both noise and reverberation, although the performance difference in the undegraded, quiet condition was relatively small. There was no difference between the scores obtained in noise and in reverberation for either group. A limited-error analysis revealed some differences in type of errors for the groups of listeners. Implications of the results are discussed in terms of the effects of degraded listening conditions on non-native listeners' speech perception.
针对母语为日语或美式英语的听众，比较了在未退化和退化听觉条件下对英语辅音的识别情况。两组各有十名受试者，分别称为非母语（日语）受试者和母语（美式英语）受试者。改良韵律测试通过嘈杂的语音（信噪比=-3分贝）或房间混响（混响时间，T=1.2秒）进行退化处理。尽管在未退化的安静条件下表现差异相对较小，但日语受试者在噪声和混响条件下的表现均低于美式英语受试者。两组在噪声和混响条件下获得的分数没有差异。有限错误分析揭示了两组听众在错误类型上存在一些差异。研究结果的影响从退化听觉条件对非母语听众语音感知的影响方面进行了讨论。
