abstract = {The growing dependence on virtual spaces for communication and collaboration has transformed interactions in numerous industries, ranging from professional meetings to education, entertainment, and healthcare. Despite the advancement of AI technologies such as three-dimensional modeling, voice cloning, and conversational AI, the convergence of these technologies in a single platform is still challenging. This paper introduces a unified framework that brings together state-of-the-art 3D avatar generation, real-time voice cloning, and conversational AI to enhance virtual interactions. The system utilizes Triplane neural representations and neural radiation fields (NeRF) for high-fidelity 3D avatar generation, speaker encoders coupled with Tacotron 2 and WaveRNN for natural voice cloning, and a context-aware chat algorithm for adaptive conversations. By overcoming the challenges of customization, integration, and real-time performance, the proposed framework addresses the increasing needs for realistic virtual representations, setting new benchmarks for AI-augmented interaction in virtual conferences, online representation, education, and healthcare. © 2025 IEEE.},
