**Digital Humans in China: An Interview with Li Yan of Dianjing Digital Technology**
Since the rise of large language models like Chat GPT, the industry of digital humans and AI-driven products has become a hot direction in China. Dianjing Digital Technology, incubated by ShanghaiTech University, has been a pioneer in this field since 2018. In an interview with Zhang News Agency, Li Yan, the General Manager of Digital Human Business, shed light on the company’s journey and vision.
Dianjing Digital focuses on two major business segments: city-level digital twins and digital humans. Though different in application, both are built on the same underlying technology stack. The digital human business has seen three stages of development, from digital avatars to brand spokespersons to the current focus on communication.
Technologically, creating an AI digital human involves a combination of computer graphics, large language models, speech recognition, and light field acquisition technology. One of the significant challenges is achieving a realistic correspondence between digital human speech and mouth shapes.
The applications of digital humans are extensive, including projects in news media and real estate parks, where they add efficiency. Dianjing Digital is also working on a sign language model to help the deaf-mute community, scheduled for release in October this year.
The future of digital humans looks promising, as Li Yan envisions them not replacing but exceeding humans in numbers, offering everything from VIP services to companionship. While technological bottlenecks exist, the technology is in a spiral development process, with improvements making digital humans more realistic and cost-effective. Li Yan believes that, with time, more people will interact with digital humans as they become more real and valuable.
