01In plain English
Given a video or photo of a face and a voice track, the tool reshapes the mouth movements so the person appears to say the new words. Dubbing tools use it to make translated video look natural.
02Why it matters when you are choosing
Bad lip sync is the first thing viewers notice in AI video. It matters most for avatar videos and for content translated into other languages.
03What to check
Ask the vendor
Check how it looks on side angles and fast speech, and which languages it has been tested on.
04The tools
34of 51 checked
34 of the 51 tools we checked offer lip sync. Each one is checked against the vendor's own pages. A tool missing from this list may not have been checked yet, which is not the same as a no.
