SoulApp (soulapp.cn), a Chinese social platform developed by Shanghai Renyimen Technology Co., Ltd., is at the forefront of integrating digital humans into social interaction. The platform has launched a full-duplex voice AI model that allows simultaneous, natural human-machine conversation—an upgrade from traditional turn-based dialogue. This system can understand emotion, respond with voice fluctuation, and maintain real-time interaction across various scenarios such as digital companionship and virtual matchmaking. Soul has introduced features like “digital avatars”, enabling users to create virtual versions of themselves for enhanced social engagement. These advancements were presented at events such as the World Artificial Intelligence Conference (WAIC). The company is also working on open-source AI projects and participates in national standards initiatives for trustworthy virtual human content management. Its proprietary SoulX large language model powers many of these functions, while its “AI Goudan” assistant demonstrates multimodal interaction capabilities.
