Force bellow
From Wookieepedia, the Star Wars wiki.
Force bellow was a power in which the user would amplify their voice using the Force.
The insane Jedi Master Joruus C'baoth used this power while on board Grand Admiral Thrawn's command ship, the Chimaera. C'baoth usually startled Gilad Pellaeon, the captain of the ship, as he entered the bridge bellowing Thrawn's name.
Ithorian Jedi were capable of using this power as well, amplifying their voices to immense proportions to destroy obstructions. The Ithorian Jedi Roron Corobb was one who used this technique in combat during the Clone Wars.
