第二语言学习者对非母语音素的感知和产生可以通过听觉训练来改善，但第二语言学习的特点往往是不同个体的表现存在很大差异。本研究考察了通过五次高变异性语音训练学习二语元音的成功与否，是否与学习者的母语元音加工能力或频率分辨敏锐度有关。一组以希腊语为母语的人接受了培训，而另一组人完成了前后测试，但没有接受培训。前后测试评估了他们在L2和L1元音处理和频率敏锐度方面的不同方面。二语和一语元音的加工通过：(A)自然英语(L2)在安静和多人喋喋不休中的元音识别，以及自然希腊语(L1)的元音识别；(B)合成英语和希腊语元音连续体的分类；以及(C)对相同连续体的辨别。对非语音连续体的频率分辨敏锐度进行了评估。频率辨别敏锐度与L1和L2元音处理的测量有关，这一发现有利于听觉处理，而不是对L2元音学习中个体差异的特定语音解释。预试中最有效的频率辨别器在训练后的英语元音感知和发音方面也是最准确的。(C)2010年美国声学学会。[DOI：10.1121/1.3506351]
The perception and production of nonnative phones in second language (L2) learners can be improved via auditory training, but L2 learning is often characterized by large differences in performance across individuals. This study examined whether success in learning L2 vowels, via five sessions of high-variability phonetic training, related to the learners' native (L1) vowel processing ability or their frequency discrimination acuity. A group of native speakers of Greek received training, while another completed the pre-/post-tests but without training. Pre-/post-tests assessed different aspects of their L2 and L1 vowel processing and frequency acuity. L2 and L1 vowel processing were assessed via: (a) Natural English (L2) vowel identification in quiet and in multi-talker babble, and natural Greek (L1) vowel identification in babble; (b) the categorization of synthetic English and Greek vowel continua; and (c) discrimination of the same continua. Frequency discrimination acuity was assessed for a nonspeech continuum. Frequency discrimination acuity was related to measures of both L1 and L2 vowel processing, a finding that favors an auditory processing over a speech-specific explanation for individual variability in L2 vowel learning. The most efficient frequency discriminators at pre-test were also the most accurate both in English vowel perception and production after training. (C) 2010 Acoustical Society of America.
