The development of speech rhythm in second language (L2) acquisition was investigated. Speech rhythm was defined as durational variability that can be captured by the interval-based rhythm metrics. These metrics were used to examine the differences in durational variability between proficiency levels in L2 English spoken by French and German learners. The results reveal that durational variability increased as L2 acquisition progressed in both groups of learners. This indicates that speech rhythm in L2 English develops from more syllable-timed toward more stress-timed patterns irrespective of whether the native language of the learner is rhythmically similar to or different from the target language. Although both groups showed similar development of speech rhythm in L2 acquisition, there were also differences: German learners achieved a degree of durational variability typical of the target language, while French learners exhibited lower variability than native British speakers, even at an advanced proficiency level.
本研究调查了第二语言（L2）习得中言语节奏的发展情况。言语节奏被定义为基于音长的节奏指标所捕捉到的时长变化。这些指标被用于检验法语和德语学习者在L2英语中不同熟练程度之间的时长变化差异。结果显示，两组学习者在L2习得过程中，时长变化均随着学习进程而增加。这表明，无论学习者的母语与目标语言在节奏上相似与否，L2英语中的言语节奏都从更音节计时向更重音计时的模式发展。虽然两组在L2习得中言语节奏的发展相似，但也存在差异：德语学习者达到了目标语言典型的时长变化程度，而法语学习者即使在高级熟练水平时，其变化程度仍低于以英语为母语的英国使用者。
