Based on LLMs and advanced AI technologies, an intelligent interactive environment for training simulation has been developed to accommodate the evolving modes and requirements of training simulations. Through expert-driven methodologies, an eventic graph encompassing the entire training simulation process is constructed. LLMs and natural language processing technologies are deeply integrated to ensure precise knowledge transmission and real-time support. Additionally, speech recognition and synthesis technologies are employed to create a multi-modal interactive interface, thereby establishing a novel human-computer interaction paradigm grounded in natural dialogue. Experimental results demonstrate that this intelligent environment can substantially enhance the efficiency of knowledge acquisition and the effectiveness of skill mastery among trainees.
