No, or, not directly. All* of the actors are Deaf and they interact with one another according to the norms of Deaf Culture. Some learning will happen, especially if one decides to focus on repeated interactions such as getting someone’s attention. Teaching Deaf Culture is not our goal, but you may find it a nice side-effect of using the app.
*Hearing actors are included in the Finger Food Cafe videos. Some follow Deaf customs, others follow Hearing customs. These are deliberate casting choices for the stories being presented.
