外语语音对比的习得要求第二语言学习者注意那些提供信息的声学维度，并在产生过程中沿着这些维度操纵值。在第二语言中发现信息维度可能会因母语（L1）中存在的对比而变得复杂。一个众所周知的例子是，以日语为母语的人很难理解或产生英语/l/-/r/的区别。在这里，我们试图通过获取英语母语单词开头的/l/和/r/产生的声学测量分布（形成峰频率和持续时间）来系统地描述这一L2学习任务。这些分布包括说话人之间（性别）、说话人内部和语音（元音环境）差异。这些结果表明，f3发作频率在分布之间提供了几乎完全的区分。还收集了日本本土产/l/和/r/的分布。日本的分布在F2和F3发病频率上可以部分分离。所有这些分布是比较分布的本土产品的日本卷舌瓣。在F2xF3空间中，皮瓣分布与本地/r/和/l/分布重叠。对本地生产的进一步测量表明，皮瓣与日本/w/的对比主要是F2的发病频率。因此，日本的/l/和/r/的产量似乎受到L2分布的信息方差（F3）和类似L1类别分布的信息方差（F2）的影响。
The acquisition of a foreign phonetic contrast requires the second language (L2) learner to attend to those acoustic dimensions that are informative for the distinction and to manipulate values along those dimensions during production. The discovery of informative dimensions in L2 can be complicated by the contrasts present in the native (L1) language. A well-known example is the difficulty that native Japanese speakers have perceiving or producing the English /l/-/r/ distinction. Here, we attempt to systematically describe this L2 learning task by obtaining distributions of acoustic measures (formant frequencies and durations) from native English productions of word-initial /l/ and /r/. These distributions include inter-speaker (gender), intraspeaker, and phonetic (vowel environment) variance. These results reveal that F3-onset frequency provides almost complete discrimination between the distributions. Distributions of native-Japanese productions of /l/ and /r/ were also collected. The Japanese distributions can be partially separated on F2 and F3 onset frequency. All of these distributions are compared to a distribution of native productions of the Japanese rhotic flap. The flap distribution overlaps the native /r/ and /l/ distributions in F2xF3 space. Further measures of native productions reveal that the flap is contrasted with Japanese /w/ mainly by the onset frequency of F2. Thus, the Japanese productions of /l/ and /r/ appear to be influenced by both the informative variance in L2 distributions (F3) and by the informative variance in distributions of similar L1 categories (F2).
