Revolutionizing L2 speaking proficiency, willingness to communicate, and perceptions through artificial intelligence: a case of Speeko application

The emergence of artificial intelligence (AI) and AI-based applications has become increasingly significant due to its transformative potential in various fields including language learning. These applications have the potential to enhance second language (L2) learners' speaking proficiency, willingness to communicate (WTC), and perception, leading to improved learning outcomes by providing personalized and interactive language practice. Using the Speeko application, this study examines the influence of AI on L2 speaking proficiency, WTC, and perceptions. The study employed a mixed-method approach in which 66 participants were randomly assigned to experimental or control groups. A Speeko application was used in the experimental group, while traditional teaching methods were used in the control group. As part of the study, data were collected through a speaking test and WTC questionnaire administered at pre-test and post-test intervals, as well as a semi-structured interview. According to the results, the experimental group had significantly higher L2 speaking proficiency, WTC, and better perceptions than the control group. Based on the findings, the incorporation of AI-based applications in language learning has the potential to enhance language learning outcomes.
