Creature voice types
Every monster has its own frequency. Match yours.
Werewolf
Human intelligence breaking down into animal fury. Growling, snarling, words fighting against the beast within. For lycanthrope and shapeshifter characters.
Sea Monster
Deep, gurgling, impossibly old. The voice of something that has been waiting in the deep since before humans existed. For leviathans and krakens.
Titan
Impossibly large. A voice that shakes the ground. Slow, deliberate, each word an earthquake. For giants, colossi, and kaiju-scale creatures.
Alien Creature
Otherworldly, clicking, buzzing cadence. Vaguely humanoid speech patterns but distinctly inhuman. For xenomorphs, parasites, and cosmic horrors.
Dragon
Ancient, commanding, dripping with power. The voice of a creature that has burned kingdoms and outlived empires. Intelligent and dangerous.
Night Stalker
Silent predator given voice. Soft, measured, hunting. Speaks only when the prey has nowhere to run. For vampiric and predatory creatures.
