Despite the increasing integration of Artificial Intelligence in language learning, limited research has explored how AI-supported immersion can be practically implemented to develop English speaking skills in EFL contexts, particularly in Indonesian higher education. The purpose of this study is to understand the implementation of AI technology-based immersion in designing English speaking skill. This research aims to identify the strategies used in integrating artificial intelligence tools to enhance students’ English-speaking abilities. The study was conducted in an international class of the English Education Department at one of state university at Semarang, Indonesia, where English is used as the medium of immersion. The class consists of 25 students and 2 lectures, including several international students from English-speaking countries. This research employs a qualitative method. The findings indicate that the implementation of AI-driven learning tools such as AI chatbots, speech recognition systems, and real-time feedback applications significantly supports students’ and lectures’ engagement and speaking fluency. AI technology creates an interactive and adaptive learning environment, allowing students to practice English communication more confidently and independently. Moreover, while AI tools were effective in supporting international communication standards, certain challenges emerged among local students who required occasional clarification in Indonesian, indicating a transitional adaptation process to full English-based AI immersion.
