用途：本研究探讨了操纵运动学习理论的几个参数对参与者的语音习得和保留的话语在一门外语（Korean.Method）的影响：32名母语为英语的参与者初到韩国的语言，每个人都给出了10个韩国句子练习和学习。研究中的自变量是练习试验的次数和反馈时间表。参与者听一个母语者说的句子，并根据时间表收到反馈。参与者的反应，然后判断由一个小组的母语韩国人在其可理解性，自然度，和precision.Results：20%的反馈和100个实践审判的组合是更有效的比其他组合的反馈和实践审判时间表为保持新的语音生产的韩国语短语都训练后1天和1周后。结论：这些研究结果与先前报道的运动学习指导原则在获得运动技能方面的应用一致。这些发现可能对第二语言学习和神经运动性言语障碍（如言语失用症）的治疗有直接的意义。
Purpose: This study examined the effect of manipulating several parameters of motor learning theory on participants' phonetic acquisition and retention of utterances in a foreign language (Korean).Method: Thirty-two native English-speaking participants naive to the Korean language were each given 10 Korean sentences to practice and learn. The independent variables in the study were the number of practice trials and the feedback schedule. The participants listened to sentences delivered by a native speaker and received feedback according to the schedule. Participant responses were then judged by a panel of native Korean speakers in terms of their intelligibility, naturalness, and precision.Results: The combination of 20% feedback and 100 practice trials was more effective than other combinations of feedback and practice trial schedule for the retention of novel phonetic productions of Korean phrases both 1 day after training and 1 week later.Conclusions: These findings are in agreement with previously reported applications of motor learning-guided principles on the acquisition of motoric skills. These findings may have direct implications for both second-language learning and the treatment of neuromotor speech disorders such as apraxia of speech.
