    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

This plugin uses voice recognition engine to generate lip-sync animation from SoundWave assets or PCM audio data. Animation is saved as curves in data assets and can be played in runtime together with audio. This approach allows to achieve well-looking lip-sync animation easily without subtitles.


Technical Details

Unlike text-to-lipsync solution, this is true voice-to-lipsync plugin. You don't need subtitles to get lips animatied, and resulted animation is much closer to speech then in case of subtitles-based solution.

Lipsync can be generated in runtime, but not in real-time.

Supported languages: English, partially Russian.


  • subtitles aren't needed;
  • can process procedural SoundWave objects created in runtime;
