# 口型同步

口型同步让角色的嘴巴和面部动作与其声音保持一致。当角色说话时，Convai 会在音频旁边发送面部动画数据，使二者保持同步——在 Unreal Engine 中无需额外的处理开销。

### 下一步

从以下开始 [口型同步的工作原理](/api-docs/zh/cha-jian-yu-ji-cheng/convai-unreal-engine-plugin/features/lip-sync/how-lip-sync-works.md) 以了解数据管线和六种口型同步模式。然后按照 [口型同步快速入门](/api-docs/zh/cha-jian-yu-ji-cheng/convai-unreal-engine-plugin/features/lip-sync/lip-sync-quick-start.md) 以便在进入参考页面之前，让口型同步在 MetaHuman 角色上运行起来。
