Next to deep voices, this is the most common auditory clue to an evil character. Raspy voices are very popular as a vocal choice for evil characters, especially Evil Old Folks.
Compared to deep voices, raspy voices have less of an intimidating effect but more of a sinister tone. This makes it particularly effective for the Big Bad of a show, especially when juxtaposed with a deep voice of his Dragon. A rasp is also good for a particularly creepy Evil Laugh. Sometimes, this trope overlaps with Red Right Hand, when the rasp is caused by a physical defect or injury, usually to the throat or otherwise to a respiratory organ. This can occur hand in hand with Vader Breath, if the character is raspy because of smoking or a physical ailment. If this accompanies Evil Old Folks, they're also a Scratchy-Voiced Senior. Compare Guttural Growler.
