There are videos demonstrating the different movements with instructions of how to do the move properly.
These videos don't have sound and are more for how to do the specific move vs follow-along. The purpose being for the focus to be on doing the move correctly and what you feel working over just following alone.
If it is a timed move, you can turn on sound cues to let you know the time is finished by turning on your phone's sound (if it is muted).
