One of the most important elements of a great mascot performance lies in your ability to communicate without actually speaking. In order to maintain the illusion that comes with portraying your unique character, you must never speak – and that includes all communication you have with your mascot handler!
There are also several practical reasons as to why a mascot performer does not speak. Speaking through a mascot head can sound very muffled and become difficult to understand for your audience. Additionally, you may have several individuals performing as the same mascot with different voices, so keeping things silent allows for more consistency among performers.
