Omniverse Audio2Face

Omniverse Audio2Face is an AI-powered tool from NVIDIA that converts spoken audio into high-quality facial animations in real time. It analyzes voice input and generates accurate facial blendshapes, enabling natural lip-syncing and expressive facial performances without the need for manual keyframing or complex animation rigs. The system supports streaming audio as well as pre-recorded dialogue, making it suitable for both live applications and offline content creation workflows.

Key capabilities include automatic phoneme-to-viseme mapping, emotion-aware facial motion, and support for a wide range of 3D characters via blendshape-based rigs. Audio2Face can be integrated into real-time engines, virtual production pipelines, and interactive applications such as games, virtual influencers, digital humans, and virtual assistants. It is designed to work within the NVIDIA Omniverse ecosystem, allowing artists and developers to preview, refine, and export animation data to other DCC tools and engines.
