Gary Orren identifies repetition as one of the logos (logical argument) persuasion principles.
LiteraryDevices.net defines repetition as “a literary device that repeats the same words or phrases a few times to make an idea clearer” and lists 11 different types of repetition (see http://literarydevices.net/repetition/, accessed 22 January 2016).
Repetition is a classic rhetorical technique and there are innumerable sources of advice on when and how to use it in speeches and presentations. Examples include:
