In the age of the metaverse, where virtual reality (VR) and mixed reality (MR) seamlessly blend with our daily lives, education is undergoing a remarkable transformation. Within this transformative landscape, Artificial Intelligence (AI) has demonstrated remarkable potential in various fields, including science and industry. In education, it presents a promising border for applying AI technology, where its transformative impact is increasingly evident. AI Advances enable tools for language learning and create more complex humans-physical world interactions. This chapter explores the intersection of AI and language learning within the metaverse era, revealing new frontiers in language education. While language acquisition has long been a dynamic field, integrating AI into the metaverse presents a groundbreaking opportunity. AI plays a pivotal role in these immersive spaces, from generating 3D objects and content without extensive human engineering to guiding the behavior of non-player characters (NPCs) for natural interactions. AI models like ChatGPT and GPT-4 empower virtual teachers and classmates to engage with students realistically. This enhancement provides lifelike interactions, breaking free from scripted responses and making the virtual classroom experience remarkably close to real-life human interaction. This chapter investigates AI’s potential influence on education within the metaverse through a comprehensive literature review. We examine recent advancements, highlight key technologies and applications, and bridge the gaps between innovations and practical educational applications. The perspective given above comes from not only academia but also from industry, ensuring a wide spectrum of the practicality of AI is provided for further discussion.
