현재 Spine에서는 자동 음성 분석과 립싱크 기능을 직접적으로 지원하지 않습니다. 립싱크 기능을 구현하려면 외부 도구나 커스텀 솔루션을 사용해야 할 수 있습니다. Rhubarb와 같은 도구를 사용해보셨지만 만족스럽지 않으셨다면, 다른 방법으로는 수동으로 립싱크 애니메이션을 제작하거나, 프로그래밍을 통해 음성 데이터에 맞춰 애니메이션을 조정하는 방법이 있습니다. Spine의 기능 확장은 개발 우선순위에 따라 결정되며, 현재로서는 립싱크 기능이 포함될 계획은 없는 것으로 보입니다.

kimdonga Thank you for sharing your opinion! At the moment we are not very enthusiastic about adding this feature, as Spinebot responded, because we do not think it would be very easy to add a more useful lipsync feature to the Spine editor than rhubarb.

Coincidentally, Erika demonstrated making lip-sync with rhubarb on a Twitch stream about two months ago, and this video may be of interest to you:

In this video, smooth mouth movements are achieved by making further adjustments to the animation after importing the lipsync results generated by rhubarb, and this mouth movement adjustment was completed in a fairly short time. The whole process may be complicated because the rig has been a long time in the making, but rhubarb is pretty good at what it does.

Also, if lip-syncing is required in a game, it should be possible to program the animation to play according to the results of the audio analysis. I guess there are a variety of ways to do this, so if you have any questions about this, you might want to post them in a new thread, along with what runtime your project is using.
