About Optimus Prime's voice

Optimus Prime is the leader of the Autobots in Transformers, voiced by Peter Cullen in the original 1980s cartoon and in the live-action films. His voice is deep and heroic, with a fatherly warmth, steady, deliberate pacing and a slight metallic resonance. Every sentence sounds like a solemn promise to protect those who need it.

Tips for the best Optimus Prime audio

Write in calm, formal, inspiring sentences that address a team or a friend; Optimus sounds right when he is leading and encouraging, not joking.
