The Audio2Face (A2F) microservice is a key component of NVIDIA's facial animation technology stack, designed to process audio input and generate corresponding facial animations. A2F integrates both server and client functionalities using gRPC to seamlessly handle data streams within a larger pipeline. This service can operate standalone or be coupled with the A2F Controller for enhanced usability through a bi-directional API.

Features

• Audio to Facial Animation: Converts speech into facial animation in the form of ARKit blendshapes.
• Server and Client Integration: Integrates server and client functionalities using gRPC.
• Standalone or Coupled Operation: Can operate standalone or with the A2F Controller for enhanced usability.
• Bi-Directional API: Provides a bi-directional API for seamless data handling.
• Compatible Infrastructure: Compatible with Ubuntu 22.04, CUDA 12.1, and NVIDIA Driver 535.54.

Benefits

• Real-Time Animation: Generates real-time facial animations from audio input.
• Flexible Deployment: Offers flexibility in deployment, either standalone or coupled with A2F Controller.
• Enhanced Usability: Improves usability with a bi-directional API.
• Seamless Integration: Ensures seamless integration within larger pipelines.
