He never speaks

Calamity Coyote from Tiny Toon Adventures

Calamity Coyote is a "techno-whiz" prodigy. He's a young genius with a knack for jerry-rigging any toy into an instrument of destruction. Little Beeper, the object of his pursuit, is always one step ahead...his experiments generally start out brilliantly, then conclude by blowing up in the coyote's face. Still, the little coyote has perseverance. He gets back on his feet, only to trip right over them again. Calamity is jealous of Beeper's athletic prowess and lives for the day when he can catch the fleet-footed bird. To that end, the coyote employs a wide array of roadrunner catching devices which he orders from the Acme Shopping Network.
