High-Variability Phonetic Training (HVPT) has been shown to be effective in improving the perception of the hardest non-native sounds. However, it remains unclear whether such training can enhance phonological processing at the lexical level. The present study tested whether HVPT also improves word recognition. Late French learners of English completed eight online sessions of HVPT on the perception of English word-initial /h/. This sound does not exist in French and has been shown to cause difficulty both at the prelexical (Mah, Goad & Steinhauer, 2016) and the lexical level of processing (Melnik & Peperkamp, 2019). In pretest and posttest participants were administered a prelexical identification task and a lexical decision task. Results demonstrate that after training the learners’ accuracy improved in both tasks. Moreover, these improvements were retained four months after posttest. This is the first evidence that short training can enhance not only prelexical perception, but also word recognition.

高变异性语音训练增强第二语言词汇处理：来自法国英语学习者在线培训的证据

高变异性语音训练 (HVPT) 已被证明可有效改善对最难的非母语声音的感知。然而，尚不清楚这种训练是否可以增强词汇水平的语音处理。本研究测试了 HVPT 是否也能提高单词识别能力。晚期法语英语学习者完成了八次关于英语词首 /h/ 感知的 HVPT 在线课程。这种声音在法语中不存在，并且已被证明在词汇处理（Mah, Goad & Steinhauer, 2016）和词汇处理水平（Melnik & Peperkamp, 2019）都造成困难。在前测和后测中，参与者接受了前词汇识别任务和词汇决策任务。结果表明，在训练后，学习者在两项任务中的准确性都有所提高。而且，这些改进在后测四个月后得以保留。这是第一个证据表明，短期训练不仅可以增强词前感知，还可以增强单词识别。
