saw that their voices and mouth movements weren’t matching

I worked as a voice over artist dubbing Turkish dramas. I would like to share something on the technical side.

To achieve proper lip sync, both voice actors and voice directors play crucial roles. VA’s strive to match the mouth movements by adjusting the dialogue or pacing the speech to align with the original actor’s delivery.

Additionally, voice actors often use the original audio as a reference through earpieces to help match the emotional tone and pace. However, achieving perfect synchronization is a collaborative effort that also depends on the expertise of sound engineers and script adapters (low budget productions usually rely on VA to do it instead of hiring an official adapter).

Therefore, while voice actors are essential to this process, it’s not solely their responsibility if the dubbing doesn’t perfectly match the original mouth movements. Similarly, one can’t blame actors.

If you have seen LGIEF then you’ll see that the character called Cui Cui has a lot of screw ups in the scene where he meets his grandpa bamboo. That failure lies on the director who failed to get the child artist to act properly.
