在对日本成人英语学习者进行视听知觉训练的过程中，通过观察含有/L/、/r/和/w/的单词的发音情况，分析了母语音位制约对二语言语知觉和发音的影响。在训练中，语音识别分数有了很大的提高。非母语单词-声母rl辨别力的改善明显与知觉、发音和神经元空间的变化有关，这代表了通过知觉、腭部和神经磁测量评估的每个领域中非母语音素和母语音素之间的不同。然而，对一些受训者来说，即使在一年的培训之后，识别辅音-rl簇仍然存在重大困难。对单词发音过程中的舌巴接触模式的分析表明，辅音-rl组比其他音位环境更容易出现发音错误，即/L/和/r/都被日语/r/替代，有时还会插入元音。结果表明，L2语音系统可以通过多通道训练获得，尽管它受到L1语音定向限制的强烈干扰。
Effects of L1 phonotactic constraints on L2 speech perception and production were analyzed during the course of audio‐visual perceptual training for Japanese adult learners of English by observing articulation of words containing /l/, /r/, and /w/. The speech identification score drastically improved during the training. The improvement in non‐native word‐initial rl distinction was clearly associated with the changes in the perceptual, articulatory, and neuronal spaces, which represent dissimilarities between the non‐native and native phonemes in each domain assessed through perceptual, palatographic, and neuromagnetic measurements. Significant difficulty in identification of consonant‐rl clusters, however, remained for some trainees even after one year of training. Analyses of palato‐lingual contact patterns during word articulation suggested that more articulatory errors tend to occur in consonant‐rl clusters than in other phonotactic contexts in such a way that both /l/ and /r/ are substituted with Japanese /r/ sometimes associated with a vowel inserted. Results suggested that the L2 phonological system can be acquired through a multimodal training, although it is strongly interfered with by L1 phonotactic constraints.
