人们已经做出了许多尝试来教导日本本土听众在感知上区分英语/r-l/（例如 rock-lock）。尽管进步是显而易见的，但最终的表现无论如何都不像母语英语。我们将训练重点放在第三共振峰起始频率上，该频率被证明是/r-l/类别成员资格的最可靠指标。我们首先在带反馈的强制选择识别训练任务中向听众展示仅 F3 起始频率变化的合成/r-l/刺激实例。学习的证据是有限的。第二个实验采用自适应范式，从仅由/r/和/l/F3频率轨迹组成的非语音刺激开始，进展到/ra–la/的合成语音实例；一半的学员收到了反馈。一些听众表现出了改进，这表明在仅使用 F3 起始频率进行训练后，/r–l/识别的某些增强是可能的。然而，这些听众中只有一小部分人表现出了训练效果泛化到训练的合成环境之外的迹象。
Many attempts have been made to teach native Japanese listeners to perceptually differentiate English/r–l/(e.g. rock–lock). Though improvement is evident, in no case is final performance native English-like. We focused our training on the third formant onset frequency, shown to be the most reliable indicator of/r–l/category membership. We first presented listeners with instances of synthetic/r–l/stimuli varying only in F3 onset frequency, in a forced-choice identification training task with feedback. Evidence of learning was limited. The second experiment utilized an adaptive paradigm beginning with non-speech stimuli consisting only of/r/and/l/F3 frequency trajectories progressing to synthetic speech instances of/ra–la/; half of the trainees received feedback. Improvement was shown by some listeners, suggesting some enhancement of/r–l/identification is possible following training with only F3 onset frequency. However, only a subset of these listeners showed signs of generalization of the training effect beyond the trained synthetic context.
