The current study re-examines how second language speech perception and production are related in the context of the acquisition of English /ɹ/ by 45 adult Japanese learners with various proficiency levels. Perception was evaluated using a two-alternative forced choice identification task, while pronunciation performance was assessed via multiple task/analysis contexts. Overall, the participants’ perception performance was correlated with the global qualities (accuracy, intelligibility) of their production ability both at controlled and spontaneous speech levels. In light of the results of acoustic analyses, however, their perception ability was only significantly predictive of their redeployment of existing articulatory parameters (i.e., lower F2 for the rate and degree of tongue retraction), not the acquisition of new articulatory parameters (i.e., lower F3 for labial, palatal, and pharyngeal constrictions).

感知-生产环节重温：日本学习者英语/ɹ/表现案例

目前的研究重新审视了 45 名不同熟练程度的成年日本学习者在习得英语 /ɹ/ 的背景下第二语言语音感知和产生的关系。使用两种可选的强制选择识别任务评估感知，而通过多个任务/分析上下文评估发音表现。总体而言，参与者的感知表现与他们在受控和自发语音水平上的生产能力的整体质量（准确性、可理解性）相关。然而，根据声学分析的结果，他们的感知能力仅能显着预测他们对现有关节参数的重新部署（即舌头回缩速度和程度的较低 F2），而不是新关节参数的获取（即。
