In spite of several tries, the video did not start the moouth movement to go with the audio. This is not a problem I have come across with earlier videos, sthey are generally very accurate.

The instruction for the audio worked correctly, and the video created the mouth movement for the second half of the audio, after a pause indicated by a comma, but the mouth did not move for the first part of the audio. I tried four times, adding a specific instruction that the mouth must move to follow all the audio, but with no success.
