AI for Becoming Fluent: Designing an App for Advanced Bilingual Speakers

This research explores the difficulties advanced second-language learners face in becoming fluent and the poten-tial of AI to enhance language learning apps. Through surveys, focus groups, and collaborative design sessions, we investigated learners' difficulties and practice habits. The participants created paper prototypes for an app targeting speaking and listening skills at an advanced level. Key findings suggest that fluency de-velopment requires exposure to diverse accents from both native and non-native speakers. The resulting design incorporates AI in the form of a chatbot with voice recognition capabilities. This study contributes to our understanding of advanced language learning needs and the potential of AI to address them, paving the way for innovative language learning solutions. Our findings highlight opportunities to develop more effective tools for learners striving to achieve fluency in their target languages.
