AI English Conversation Coaching Platform in the Metaverse: Focused on Korean Users

초록

In Korea, English education primarily focuses on exam-oriented learning, making it challenging to improve practical conversational skills. Additionally, Konglish or Koreanized English significantly hampers improving English conversational abilities. To solve this problem, this paper proposes a metaverse platform that offers English conversation functionalities in various scenarios, specifically targeting Korean users. The virtual environment for English conversation is created using the Unity Engine, leveraging the high performance and graphic quality provided by the URP. Digital humans are utilized as NPCs to enhance realism. The proposed platform allows users to select from various locations (City, Subway, Cafe, School) and engage in English conversations with NPCs based on the chosen setting. This English conversation functionality leverages GPT-based AI to provide interview simulation. Upon completion of a conversation session, the AI generates a conversation report to provide feedback to the user. This report offers a detailed analysis of the user's weaknesses and areas for improvement, contributing to the enhancement of their English conversational proficiency. Consequently, the proposed platform delivers an immersive English learning environment, facilitating effective English education through realistic and engaging experiences.
