The Emperor's Voice represented a high-ranking echelon of Dark Side Adept who pledged their allegiance to Emperor Palpatine during the era of the Galactic Empire.
This role mirrored the functions of other groups such as the Emperor's Hands, the Emperor's Eyes, and the Emperor's Reach. Notably, Maarek Stele held the distinction of being an Emperor's Voice, in addition to serving as both a Reach and a Hand.
