This research explores AI Twins, lifelike digital avatars enabling real-time interaction through advanced AI-driven speech synthesis, expressions, and contextual understanding. It compares two implementations: a closed-source system utilizing tools like Synthesia and Eleven Labs for high-quality video and audio, and an open-source alternative with Nvidia Riva, Nemotron LLM, Wav2Lip, and Sadtalker for speech and lip-sync. Both use Retrieval-Augmented Generation (RAG) and AI Agents for enhanced domain intelligence, offering applications in personalized education, training, customer support, and virtual companionship.
