Mayer’s 12 Principles of Multimedia Learning

The Personalisation Principle - Conversational not Formal

The Personalisation Principle says that humans learn best from a more informal, conversational voice than an overly formal voice. Having a more casual voice actually improves the learning experience.

How to use the Personalisation Principle:

You can use this by keeping your language simple and casual. Try to avoid overly professional sounding text, or long, complex words. It also helps to use the first person (you, I, we, our). This is where it helps to consider your audience demographics and try to match the tone of your voiceover to enhance personalisation.
