Repeated reading (RR) helps learners, who have little to no experience with reading fluently to gain confidence, speed and process words automatically. The benefits of repeated readings include helping all learners with fact recall, aiding identification of learners' main ideas and vocabulary, increasing comprehension, leading to faster reading as well as increasing word recognition accuracy, and assisting struggling learners as they transition from word-by-word reading to more meaningful phrasing. Thus, RR ultimately helps in improvements of learners' oral fluency and narrative production. However, there are no open audio datasets available on oral responses of learners based on their RR practices. Therefore, in this paper, we present our dataset, discuss its properties, and propose a method to assess oral fluency and narrative production for learners of English using acoustic, prosodic, lexical and syntactical characteristics. The results show that a CALL system can be developed for assessing the improvements in learners' oral fluency and narrative production.

分析重复阅读对计算机辅助语言学习口语流利度和叙事产生的影响

重复阅读 (RR) 可以帮助几乎没有或没有流利阅读经验的学习者获得信心、速度和自动处理单词。重复阅读的好处包括帮助所有学习者回忆事实，帮助识别学习者的主要思想和词汇，提高理解力，从而加快阅读速度并提高单词识别的准确性，并帮助有困难的学习者从逐词过渡单词阅读更有意义的措辞。因此，RR 最终有助于提高学习者的口语流利度和叙事能力。然而，没有关于学习者基于他们的 RR 实践的口头反应的开放音频数据集。因此，在本文中，我们展示了我们的数据集，讨论了它的属性，并提出了一种使用声学、韵律、词汇和句法特征来评估英语学习者口语流利度和叙事产出的方法。结果表明，可以开发一个 CALL 系统来评估学习者口语流利度和叙事制作的改进。
