Anonymized Auxiliary Verb Error Dataset (Uzbek EFL Learners)

This dataset contains a collection of audio recordings from 11 Uzbek EFL learners produced as part of a study on the use of English auxiliary verbs. The recordings capture spoken responses during grammar-focused elicitation tasks, where participants used auxiliaries such as be, have, and do in various tenses and syntactic contexts. The data were collected for the research article “Error Patterns in the Use of English Auxiliary Verbs among Uzbek EFL Learners: A Descriptive Analysis.” Each file is anonymized and labeled according to the participant code and task type. The dataset illustrates typical pronunciation and grammatical difficulties Uzbek learners encounter in spoken English and is suitable for phonetic, grammatical, and cognitive-linguistic analyses.
