Abstract:

Lexical complexity is a multidimensional construct which includes the sophistication, diversity and density of vocabulary produced in spoken or written communication. Measures of lexical complexity have applications in language assessment and language teaching and can inform research on language acquisition. Several indices and automatic tools have been developed to analyse lexical scores, and corpus linguistics has been the main method in this area. However, few studies have investigated lexical complexity in L2 spoken production since few large spoken learner corpora are available (Gablasova & Bottini, 2022). Also, the existing research on L2 speakers has mainly focused on the effect of proficiency, while task effects have not been fully investigated yet. This study aims at expanding prior research on lexical complexity in L2 speech, comparing monologic and dialogic tasks. It uses the 4.2-million-word Trinity Lancaster Corpus (Gablasova et al., 2019) based on a high-stakes exam of L2 spoken English.
