抽象。本文考察了韩国语摩擦音（松/s/和紧/s*/）在三种元音语境（/a/、/i/和/u/）中的声学特征。AE学习者根据他们的熟练程度分为两组。从声学上讲，韩语/s*/与英语/s/比后者与韩语/s/更相似。从A/F时长比来看，越接近的音（韩语/s*/）越容易被高级韩国语学习者发出，而从振幅差来看，无论其水平高低，高级韩国语学习者都无法区分韩语摩擦音。从平均A/F时长比来看，英语高级学习者正确地发出了韩语/s*/，而英语高级学习者和初级学习者错误地发出了韩语/s/，而英语高级学习者和母语者在发出韩语摩擦音时使用了不同的策略。AE KSL高级学习者在区分韩国语摩擦音/s/和/s */时表现出时长优先于振幅的特点，而AE KSL初级学习者在区分韩国语摩擦音/s/和/s*/时没有表现出明显的声学线索效应。在韩国语自主学习者的韩国语摩擦音/s/和/s*/的言语产出中，除了学习L2的时间之外，其他因素也应该被用来解释L2语音的习得。
Abstract. This article examines the acoustic characteristics of Korean fricatives (lax /s/ and tense /s*/) in three vowel contexts (/a/, /i/, and /u/) in the speech of AE learners of Korean. AE learners fall into two groups based on their proficiency. Acoustically, Korean /s*/ is more similar to English /s/ than the latter is to Korean /s/. In terms of A/F duration ratio, the more similar sound (Korean /s*/) was easier for AE advanced learners of Korean to produce, while in terms of amplitude difference AE learners did not distinguish the Korean fricatives at all regardless of their proficiency level. In terms of the mean A/F duration ratio, the Korean /s*/ was authentically produced by AE advanced learners, but AE advanced and beginning learners of Korean inaccurately produced Korean /s/ was L2 advanced learners and L1 speakers used different strategies in the production of Korean fricatives. AE KSL advanced learners showed primacy of duration over amplitude, while AE KSL beginning learners showed no significant acoustic cue effects in differentiating the Korean fricatives /s/ and /s*/ in production. As in the speech production of Korean fricatives /s/ and /s*/ by AE learners of Korean, factors other than years spent learning L2 should be considered to explain the acquisition of L2 sounds.
