The AI digital human cabin is an immersive intelligent interaction device built on technologies such as artificial intelligence, holographic projection, and multi-modal interaction. It presents highly realistic digital human images through the integration of virtual and real elements and provides natural and smooth human-computer interaction services. Real-time Interaction ‌ : Combining natural language processing (NLP) and speech synthesis (TTS) to support continuous conversation and intent tracking. Integrate speech recognition (ASR), visual perception, gesture recognition, etc., to achieve multi-dimensional responses of text, speech, expressions and actions. The naked-eye 3D effect is achieved through optical imaging technology, allowing users to experience immersive interaction without wearing devices. The deep learning model trained on trillions of data endows digital humans with logical reasoning, knowledge fusion and dynamic learning capabilities.
