This study explores F0 entrainment in second language (L2) English speech
imitation during an Alternating Reading Task (ART). Participants with Italian,
French, and Slovak native languages imitated English utterances, and their F0
entrainment was quantified using the Dynamic Time Warping (DTW) distance
between the parameterized F0 contours of the imitated utterances and those of
the model utterances. Results indicate a nuanced relationship between L2
English proficiency and entrainment: speakers with higher proficiency generally
exhibit less entrainment in pitch variation and declination. However, within
dyads, the more proficient speakers demonstrate a greater ability to mimic
pitch range, leading to increased entrainment. This suggests that proficiency
influences entrainment differently at individual and dyadic levels,
highlighting the complex interplay between language skill and prosodic
adaptation.

这项研究探讨了第二语言（L2）英语演讲模仿中 F0 演化的问题，在交替阅读任务（ART）中。结果表明，L2 英语熟练程度与演化之间存在微妙的关系：熟练程度较高的演讲者在音高变化和下降方面通常表现出较少的演化。然而，在一对一的情况下，熟练程度较高的演讲者表现出更强的模仿音高范围的能力，导致进一步的演化。这表明熟练程度在个体和对位级别上对演化产生不同的影响，突出了语言技能和韵律的复杂相互作用。
