NTT Research and its affiliated institutions are advancing the development of digital humans as part of broader R&D efforts in AI, digital twins, and human-centric computing. Their work includes projects like “CONN,” which synchronizes human motion and speech to create lifelike digital human avatars. NTT aims to integrate these avatars with large language models (such as "tsuzumi") to create more natural, human-like communication agents. Their efforts span healthcare (e.g., bio-digital twins for cardiac treatment), customer service, and smart city applications. Collaborations with academic institutions like Harvard and government partners are part of their initiative to create a well-being-oriented, cyber-physical society through the IOWN (Innovative Optical and Wireless Network) vision. The technology focuses on enhancing realism, interactivity, and personalization in digital human experiences, merging cutting-edge AI with responsive and empathetic virtual agents.
