结论在以英语为母语的环境中，通过充分的自然暴露，日语母语者可以克服等值分类的影响，形成一个独立的、独立的二语音段类别，其发音与第一语言的发音相似。这种暴露进一步抑制了L1语音迁移的影响，L1语音迁移阻碍了特定语音环境中不同的L2语段的发音。所需接触的准确门槛将在未来的研究中解决。
ConclusionsWith adequate natural exposure in an English-speaking environment, Japanese native-speakers can overcome effects of equivalence classification to develop a separate, independent L2 segmental category for a sound that is similar to one in the L1. Such exposure further curbs the effects of L1 phonological transfer which impedes the articulation of distinct L2 segments in specific phonetic contexts. The precise threshold of exposure required is to be addressed in future research.
