Lip Sync Sprite Animation in LibGDX

Is there any free sprite package to achieve lip syncing animation ? This is what I have in mind.

1. User will input text
2. The character will talk with the appropriate lip sync.

I know there are several plugins about this in unity but haven’t found any implementation in libgdx. So I am assuming the way to go will be create a texture atlas with several mouth position and shape. Create animation objects in libgdx with several frame positions. and play them based on vowels in string and words.

What is the way to go here ? Need advise.
