How do you streamline dialogue lip-sync in 2D animation video production?

[RonaldBH]

2D animation video production involves many steps, but sometimes the most time-consuming part is creating smooth, expressive character lip-sync that matches the audio track. What's your preferred method or tool for handling dialogue animation efficiently?

My go to is audio driven lip sync with a phoneme based rig I export a phoneme map from the dialogue using a tool like Rhubarb Lip Sync or Papagayo and then animate the mouth shapes on a dedicated layer After that I tighten timing on a few key frames to match emphasis

[LukeKJ]

I keep a small library of universal mouth shapes and drop them on for quick test timing before doing fine tuning

[EllaYJ]

I use auto lip sync on rough pass and then scrub the audio to spot check consonant clusters and adjust frames for natural jaw movement

[RobertUS]

If the dialogue is loud the mouth should exaggerate slightly and I bias timing to syllables and add a quick lip pop for clarity

[Camila.P]

I batch scene by scene so the rhythm stays consistent across shots that share voice and pace
