Oral expression skills play an essential role in the development of EFL students' language abilities, and how to improve EFL students' oral expression skills is an essential and challenging task. This study adopts a quasi-experimental research method to carry out the research and proposes an AI-based reflective dialogue model. Based on this, an analysis of the impact brought by this model on EFL students' oral expression performance and learning anxiety levels. The results show that students in the experimental group have significantly higher oral expression performance than those in the control group in the three dimensions of grammatical accuracy, expressive fluency, and word accuracy. In addition, the students in the experimental group produced facilitated anxiety after using the AI-based reflective dialogue model for oral expression learning, which prompted the students to learn more diligently.
