TCADH (Tencent Cloud AI Digital Human) uses multiple AI technologies, such as voice interaction and image model generation, to achieve voice synchronization with lip motion and personification of facial expression and action. It is widely used in two scenarios: virtual image broadcast and real-time voice interaction. Virtual image broadcast, which is implemented in media, education, exhibition service and other scenarios, can quickly synthesize audio and video files according to text contents. Real-time voice interaction supports instant online dialogue, enabling intelligent customer service, voice assistant and other scenarios.
