Oculus Lipsync for Unreal Engine

The Oculus Lipsync Unreal plugin is a tool used to sync avatar lip movements to speech sounds. Oculus Lipsync analyzes an audio input stream from a microphone input or an audio file, and either offline or in real-time predicts a set of values (called visemes) which may be used to animate the lips of an avatar.

Oculus Lipsync offers an Unreal plugin for use on Windows or macOS.
