PowerPoint has different types of Slide Layouts. Depending on which type of presentation you make, you will use more or less different slide layouts. Some Slide Types are: title slides, section heading slides, picture with caption slides, blank slides.
A mix between in-person and virtual participants for an event or a lecture is called a hybrid audience. Working with a hybrid audience may be challenging, as it requires the presenter to find ways to engage both the live and the virtual audience.
A vocalized pause means the pause when the silence between words is filled by the speaker with vocalizations like "um", "uh" and "er".
Audience Dynamics means the motivations, attitudes, beliefs and values, which influence the listener's behaviour.
