To be honest, the lip-sync effect is not very good and doesn't compare well to other products. However, it's not an issue when used for entertainment or comedy videos.
Human movement, head turning, face occlusion, and multiple faces in a video present a range of challenges. Our lipsync model has been extensively trained and generally handles most scenarios well. However, if you are not satisfied with the lipsync results, please reach out to us at support@vozo.ai or report the issue on our Discord server https://discord.gg/xQvFmznd. Your feedback is invaluable to us and will help us improve our service!
