本研究探讨了/r/-/l/知觉识别训练对成人日语使用者产生/r/-/l/的影响。受试者被记录产生英语单词，对比/r/和/l/之前和之后，在一个延长的时间段的/r/-/l/识别培训使用高变异性的演示格式。所有受试者都表现出显着的知觉学习的培训计划的结果，这种知觉学习推广到新的谈话者所说的新项目。作为知觉训练的结果，日本受训者的/r/-/l/口语发音的改善使用两个独立的测试与母语为英语的听众进行评估。首先，前测和后测令牌的直接比较表明，知觉学习的结果，/r/和/l/生产的感知评级显着改善。第二，在两个选择的最小对识别过程中，英语听者比前测者更准确地识别后测作品。这些结果表明，知觉学习过程中获得的知识/r/和/l/转移到生产域，从而提供了新的信息之间的关系，语音感知和生产。(C)1997年美国声学学会。
This study investigated the effects of training in /r/-/l/ perceptual identification on /r/-/l/ production by adult Japanese speakers. Subjects were recorded producing English words that contrast /r/ and /l/ before and after participating in an extended period of /r/-/l/ identification training using a high-variability presentation format. All subjects showed significant perceptual learning as a result of the training program, and this perceptual learning generalized to novel items spoken by new talkers. Improvement in the Japanese trainees' /r/-/l/ spoken utterances as a consequence of perceptual training was evaluated using two separate tests with native English listeners. First, a direct comparison of the pretest and post-test tokens showed significant improvement in the perceived rating of /r/ and /l/ productions as a consequence of perceptual learning. Second, the post-test productions were more accurately identified by English listeners than the pretest productions in a two-alternative minimal-pair identification procedure. These results indicate that the knowledge gained during perceptual learning of /r/ and /l/ transferred to the production domain, and thus provides novel information regarding the relationship between speech perception and production.
