Mapping the spoken vocabulary knowledge of second language (L2) learners of English

在本研究中，我们探讨了词汇多样性（不同文本长度和分析单位）、话语流畅性和一般口语熟练程度之间的潜在关系。我们的目标是报告一项对来自英国一所大学的大约105名参与者的调查，他们被分为三个不同的雅思水平。我们探索了一个参与者本科演讲的语料库。我们使用三个基本的LD测量和三个复杂的LD测量来研究和比较flemma，引理和简单计数对LD测量说话可预测性的影响。根据早期的研究（treffer - daller 2013），我们还研究了不同的文本长度。

In the current study, we explore potential relationships between lexical diversity (with different text lengths and analysis units), utterance fluency, and general speaking proficiency. We aim to report on an investigation of approximately 105 participants from a UK university divided into three different IELTS proficiency levels. We explore a corpus of participant undergraduate presentations. We investigate and compare flemma, lemma, and simple count influences on LD measure speaking predictability, using three basic LD measures and three sophisticated measures. Following earlier research (Treffers-Daller 2013), we also examine different text lengths.
