越来越多的证据表明，听觉处理能力的个体差异与整个生命周期中语言习得的速度和最终成就之间存在广泛的关系，包括青春期后第二语言（L2）语音学习。然而，人们对特定听觉维度的处理精度如何与特定 L2 节段对比的获取之间的关系知之甚少。在 100 名具有不同课堂和沉浸体验的已故日英双语者的背景下，当前的研究着手调查非语言声音中几个听觉维度（F3 频率、F2 频率和持续时间）的感知与英语 [r]-[l] 感知和生产能力之间的联系。尽管参与者的传记因素（是否存在沉浸感）在学习这种对比的成功与否上造成了很大的差异，但结果也与他们对最可靠的新听觉线索（F3 变异）和不太可靠但已经熟悉的线索（F2 变异）的敏锐度有关。这一发现表明，个体在感知、利用和充分利用特定声学维度传达的信息方面可能存在差异。当感知更自然的口语输入时，可以通过众多线索的组合来区分语音对比，一些人可以通过以互补的方式使用类似母语和/或非母语的策略来获得高水平的 L2 语音熟练程度。
Growing evidence suggests a broad relationship between individual differences in auditory processing ability and the rate and ultimate attainment of language acquisition throughout the lifespan, including post-pubertal second language (L2) speech learning. However, little is known about how the precision of processing of specific auditory dimensions relates to the acquisition of specific L2 segmental contrasts. In the context of 100 late Japanese-English bilinguals with diverse profiles of classroom and immersion experience, the current study set out to investigate the link between the perception of several auditory dimensions (F3 frequency, F2 frequency, and duration) in non-verbal sounds and English [r]-[l] perception and production proficiency. Whereas participants' biographical factors (the presence/absence of immersion) accounted for a large amount of variance in the success of learning this contrast, the outcomes were also tied to their acuity to the most reliable, new auditory cues (F3 variation) and the less reliable but already-familiar cues (F2 variation). This finding suggests that individuals can vary in terms of how they perceive, utilize, and make the most of information conveyed by specific acoustic dimensions. When perceiving more naturalistic spoken input, where speech contrasts can be distinguished via a combination of numerous cues, some can attain a high-level of L2 speech proficiency by using nativelike and/or non-nativelike strategies in a complementary fashion.
