How do you fix lip sync

[Suraceif]

I cant seem to get the lip sync to accuratly scan my face. The camera doesnt seem to scan well and the audio cant pick up certain sounds.

Lipsync camera is for smile and surprised only. The rest come from audio analysis. 

Not sure what your hardware is, but one strategy is to record a sound file, play it back to make sure no background noise etc,  then use compute lipsync from audio clip so you can guarantee the sound quality and volume of the audio file. Adobe Audition can be useful to reduce background noise if needed.
