CRI LipSyncis a voice analysis lip sync middlewarethat usesdeep learning voice analysis technology to automatically generatenatural mouth patternsfrom voice data.
It generates natural mouth movements that match the dialoguein in-game conversation scenes.

In November 2025, we released "CRI LipSync Alive," which specializes in pre-analysis.
As the next-generation version of "CRI LipSync," this is a specialized pre-analysis tool that can output up to 14 types of animation curves, including 5 types of vowels and 9 types of consonants.
