Actually i think they do voice acting before getting into programming. That’s the standard on an animated film anyway and it would make more sense to have the recording so they can lip sync early instead of doing all the programming and then waiting till the recording is finished. But yeah your right and they may need to do pickups if the recording is bad quality or the tone of the scene changes.
