Abstract：
This study investigated the effect of different types of phonetic training on potential changes in the production and perception of English vowels by Arabic learners of English. Forty-six Arabic learners of English were randomly assigned to one of three high variability vowel training programs: Perception training (High Variability Phonetic Training), Production training, and a Hybrid Training program (production and perception training). Pre- and post-tests (vowel identification, category discrimination, speech recognition in noise, and vowel production) showed that all training types led to improvements in perception and production. There was some evidence that improvements were linked to training type: learners in the Perception Training condition improved in vowel identification but not vowel production, while those in the Production Training condition showed only small improvements in performance on perceptual tasks, but greater improvement in production. However, the effects of training modality were complicated by proficiency, with high proficiency learners benefitting more from different types of training regardless of training mode than lower proficiency learners.
摘要：
本研究调查了不同类型的语音训练对阿拉伯英语学习者对英语元音的产生和感知的潜在变化的影响。46名阿拉伯语英语学习者被随机分配到三个高变异性元音训练计划之一：感知训练（高变异性语音训练），生产培训,和混合培训计划（生产和感知培训）。测试前和测试后(元音识别，类别歧视,噪声中的语音识别，和元音产生）表明所有训练类型都导致感知和产生的改善。有一些证据表明，改进与训练类型有关：在感知训练条件下的学习者在元音识别方面有所改善，但在元音产生方面没有改善，虽然那些在生产培训条件下的人在感知任务上的表现只有很小的提高，但产量有了更大的改善。然而,训练方式的效果因熟练程度而变得复杂，无论培训模式如何，高熟练程度的学习者都比低熟练程度的学习者从不同类型的培训中受益更多。
