NVIDIA Omniverse Audio2Face is a real-time AI tool that animates 3D characters’ facial expressions based on audio input. It analyzes speech and generates corresponding lip movements, expressions, and emotions on digital avatars. The tool is part of NVIDIA’s Omniverse suite, designed for creators in gaming, film, and interactive media. Audio2Face helps streamline the animation process, making it easier to sync character animations with voiceovers for realistic and dynamic performances.
