Go to the voice track and expand it and look at the Lips track.
There you will see the Lip Phonemes.
Select one and press the delete key to remove it and the lips will not change.
Also, sometimes you might have to add a "None" phoneme after a word to close the mouth.
Double click on the Lips track to open the "Lip Sync" editor where you can add or change existing lip phonemes.
